186 ÷ 6

There are a number of ways to approach this problem. Before we look at them, let's define each term of the division problem. 

186 is the dividend, or the number to be divided by another number.

6 is the divisor, or the number you divide by.
The answer to the problem (31 in our case) is called the quotient.

Multiply Instead

"I know 6 times 30 is 180, plus one more 6 gives me 186; so my answer is 31."

Failure Should be an Option

I recently got my hands on an amazing article by Edward Burger about his experience with grading students in his college courses on their ability to fail.

If students are afraid of making mistakes, it means they are afraid of struggling, of trying something new, of being creative, of thinking in a different way. If grit is the key to success, we teachers are well positioned to nurture the quality.

The fear of failure is a learned one. As teachers, we are often so strapped for time that we don't think spending time on mistakes is a good use of what little time we have; we need to make sure the student can get the right answer so we can move on to the next topic. I think that mistakes allow people an amazing opportunity to ask themselves,  "Why didn't that work? Would it ever work?" Unfortunately, in education we tend to ignore those opportunities and instead focus on getting the correct answer. But then we bemoan our student's inability to think critically or persevere when confronted with something slightly more challenging than the last thing they did.

So what does the research tell us about how to allow students to be incorrect and still use our time efficiently? How do we build in time and opportunities for productive failure? The classroom environment we cultivate can have huge effects. Edward Burger provides his class with an end of course grade for how well each student failed. He asked his students to write a personal reflection essay about their experience with their own failure throughout the course and to give themselves a grade from 0 (did not make any mistakes) to 10 (made lots of mistakes and learned from them). He ended up using the students' own assessment of themselves for their final grade, which counted as 5% of their final grade. The students who received the highest grade were the students who admitted to having moments of failure and were able to reflect on those moments and learn from them. Other teachers have shared personal stories of their own failures and what they learned from those failures at the beginning of the year.

In her book, Rethinking Grading, Cathy Vatterott compares the learning process to being an actor in a play. An actor has many rehearsals (practice) and receives feedback on how to improve their performance during this time. The dress rehearsal (formative assessment) serves to show the actor how close they can come to getting it right. Finally, the actual performance seen by the public, serves as the only thing that "counts," or the thing that gets the grade. She also reminds us that "learning is not error-free - mistakes will be made. If we want to encourage students to view mistakes as a necessary step in learning, we need to remove the threat of grading while they are learning." Instead, she encourages teachers to provide "informative and nonjudgmental" feedback to students during the learning process.

Help create an environment that encourages productive struggle. 

• Make posters with quotes from famous inventors, athletes, and business people to decorate the classroom. Include quotes about failure and perseverance.
• Praise students in a way that helps them feel more comfortable making mistakes. Some suggestions include, "Wow, you really practiced that, and look how you've improved." "See, you studied more and your grade on this test is higher." "You tried different strategies and you figured out how to solve the problem." "You stuck to this and now you really understand it."
• Use feedback instead of grades during the learning process. 
• If your students ask you a question that you don't know the answer to, tell them, "I don't know, but we can find out!" Let them see what it looks like to not know an answer and what it looks like to discover it.

In past semesters, I have tried a few different ways to elicit incorrect responses from my students, borrowing heavily from great educators such as Dan Meyer and Carol Dweck. I have praised the effort and work my students have put into solving a problem rather than how smart they are. I have presented math problems, and rather than asking for the correct answer, I've asked them for answers they know will be too high or too low, and then asked other students to explain why that particular answer is reasonable. After reading this article, I am excited about creating a culture in my classroom that encourages mistakes and reflection.

Six Assumptions Teachers Make

We all make assumptions about things our students know and don't know. Sometimes these assumptions are correct, and present no problems. Often, however, those assumptions are incorrect and throw off our carefully planned lessons. Today's post is about some of those assumptions, and ways we can slow down and plan differently to help our students and ourselves succeed.

We assume that our students know...

1. How to behave in class.  No matter what age we are teaching, we tend to assume that our students know how to behave. When students fail to meet behavior expectations, more often than not we respond by sending them out of the room or assigning consequences. While consequences are important, we need to make sure our expectations for behavior are clear and consistently implemented in order to set our students up for success. Taking the time to reteach those expectations after any school breaks, or if things seem to be getting generally out of hand, will ultimately save time in the long run by minimizing disruptive behavior. Additionally, if the expectations you set at the beginning of the year do not seem to be working, you can always change them, as long as you make it clear to the students what changes have been made.
2. How to take notes.  Children are not born with the ability to take organized notes. This is a skill that is taught to them. No matter how old your students are, assume that they do not know how to take notes, and teach them that skill. I used interactive notebooks in my classroom, and would project exactly what and how the students needed to copy the notes into those notebooks. I taught 6th grade, so there was very little leeway given to my students about how they were to take notes. This worked very well for my classroom. If you teach older students, they might have a method that works especially well for them. If that is the case, allow those students to keep doing what they're doing. However, this will not be true for all of your students, so make sure you set up a method that works for you and teach that to your classes.
3. How to study.  Because students tend to take disorganized notes, they do not know how to use those notes for future studying. Using lessons to help the students practice using their notes to study is a great use of time. Some ways to set the lesson up could include letting students use their notes to play a game with a partner such as Battleship, Flash Card Flip, Flash Card Match, I Can..., or Task Card Pass. Additionally, you could set up a notes scavenger hunt by creating a crossword puzzle that uses the terms from notes and the definitions as clues. 
4. How to manage their time.  Many teachers, especially elementary teachers, think that by giving homework they are teaching students time management skills. This is another unfortunate assumption. What ends up happening is the parent's ability to manage their time wisely is tested instead. We can teach students time management skills in a better way by timing activities in our classroom and allowing students to see the timer we are using. Timers can be used for everything from bell ringers, to independent practice time, to bathroom use (if you are a teacher that takes the entire class to the restroom at various times). If students are reading a long passage or solving multiple problems, we can help them by writing on the board where they should be at different time intervals. For example, "In 5 minutes, you should have finished the first paragraph," or "In 6 minutes, you should have completed the first three problems."
5. How to read on grade level.  Depending on the type of school district you are teaching in, you might have anywhere from 5%-60% of your students reading well below grade level. No matter what subject you teach, we are all reading teachers. Every subject requires students to read, even if it is only the directions. By making sure you are supporting what the ELA teachers are doing in their classrooms, you are also supporting your students and yourself in your own classroom. This support can be as simple as rewriting a text to match the student's reading level, or if the majority of your students struggle, you can close read passages together.
6. How to solve basic math problems.  Students often enter their middle school years with a poor conceptual understanding of basic mathematical operations such as subtraction, division, and multiplication. This causes many other issues later on, as one might expect. By using manipulatives and illustrations to make the math more concrete, students begin to understand the operations better. While many of us were not taught using manipulatives, or maybe even how to use them in our classrooms, it is worth the time needed to explore them for ourselves and the time needed to allow our students to use them in class. It is a much better use of our time than spending weeks and weeks trying to remediate and reteach concepts later in the year.
7. How to think about the text or problem being presented to them.  Again, this is a skill that is learned as we grow up, which means that as teachers, it is our responsibility to teach it to our students. We can do this by coaching students to ask themselves questions as they are working on their independent practice. For math, those questions might look like: 1. What information do I know? 2. What am I being asked to find? 3. What operations can I use to solve this problem? For any class that requires reading comprehension, those questions might look like: 1. What is the author telling me here? 2. Are there any hard or important words? 3. What does the author want me to understand? [For literature: 4. How does the author play with language to add to meaning?]

Before the First Day of School

As the school year is winding down, now is the time for reflection and self-evaluation. What worked this year? What didn't? What changes would you like to make in your classroom for next year?

If you are about to enter the classroom for the first time, now is the time to start thinking about how you want to set up your room. Looking to other teachers is the best way to figure out what will work and what won't. Talk to veteran teachers about your plan and listen to their feedback. Sometimes our ideas don't actually pan out very well in practice, and this is one of those times where learning from someone else's mistakes is going to make your life much easier.

I've created a checklist to help you get organized and hopefully help reduce stress and feeling overwhelmed by what you need to do before the students walk in on that first day of school.

Taking Care of Yourself as a Teacher

When you are a teacher, it is easy to lose sight of your own needs. It took me until Spring Break of my third year in the classroom to realize I hadn't been taking care of myself my entire career as a teacher. If I took time off over the weekend to sleep or visit family or go hang out with friends, I felt guilty. I celebrated the first time I went into a store and did not leave with something for my classroom or students with a Facebook post and some delicious Mexican food. This was well into my second year of teaching, and I still remember it vividly.

If you are about to become a teacher, or have been a teacher for years, don't fear. This is not a rant about how hard teaching is or all the burdens we take on in that role. This is a post about the ways you can take care of yourself as a teacher. Or as a human person. Some of these things might seem like common sense, and if they are things you already do, Hooray! Keep doing them! My hope is that I will give you some new ways to take care of yourself during the school year, and every day outside of it as well.

Take Care of Your Health

• Eat healthy snacks throughout the day.
• Stay hydrated.
• Use the restroom when you need to! (Ask another adult to watch your class if you have to. Do the same for others if they ask you.)
• Take vitamins.
• Wash your hands, wipe down desks and doorknobs, and use hand sanitizer if soap isn't available. Do this religiously!
• Get enough sleep. Schedule time for this if you have to. Set alarms on your phone to remind you that it's time for sleep. Sleep is important!!

Take Care of Your Emotional Wellbeing

• Write (poetry, blog, diary entries, letters, etc.)
• Read good books (and not just books about teaching!)
• Go out with friends. Try to go out with friends who aren't teachers occasionally!
• Make something (cookies, cakes, food, bread, paintings, drawings, pottery, etc.)
• Watch TV and movies.
• Go for a walk/run/bike ride.
• Meditate
• Go to a counselor regularly (this job is hard, so let someone else help!)
• Talk to friends and family who aren't nearby
• Keep a journal at school and document the "moments of win," no matter how small they may seem.
• Make positive phone calls home and send good notes home with students.
• Set a work schedule and stick to it. If school lets out at 4, stay until 5 and work. After 5, if it's not finished, you'll get to it tomorrow. If you've scheduled 3 hours for work on Saturday, you only get those 3 hours. After that time is up, you have to go do something else.

Remember

• Never feel guilty for taking care of yourself first! You cannot be an effective teacher if you are sick or tired or stressed out all the time.
• Mistakes will be made. Learn from them and move on. Do not strive for perfection, strive for "better than yesterday."

Curriculum Issues

I taught for two years with no centralized curriculum or standards-aligned textbooks to use. While many veteran teachers might love this amount of freedom, it was terrifying for a new teacher. I was able to make it work by focusing on the standards and pulling resources from multiple sources to create something usable for my students, but finally found a free curriculum to use my third year in the form of EngageNY. While it was not the end all be all answer, it was a wonderful place for me to start. Because I'd focused so heavily on my state's standards, I was able to modify lessons and units within EngageNY to fit those standards as well as meet the levels of my students and my own teaching style.

I highly recommend finding some sort of curriculum to use as a foundation for your lesson planning. I say this with a word of warning, however. Textbook and curriculum publishers have been notorious for placing whatever sticker they need to on the cover of their publication and selling it to states. This means that just because it says "Common Core Aligned," or "TEKS Aligned," etc., does not necessarily mean it is. [You can check out EdReports for an independent review of educational materials.]

Even if it is properly aligned, often the material isn't rigorous enough to be used without any modifications. Sometimes the questions are posed as "higher order thinking questions," but provide too much information to the students, and end up being a simple substitution problem. Other times, it is marked as a "modeling problem," but, again, all of the information is provided for the students. Here is a great example from Dan Meyer's blog:

Mathematical modeling is defined in similar terms by the Common Core State Standards, the modeling cycle, or the IB:

1. identifying variables in the situation and selecting those that represent essential features,
2. formulating a model by creating and selecting geometric, graphical, tabular, algebraic, or statistical representations that describe relationships between the variables,
3. analyzing and performing operations on these relationships to draw conclusions,
4. interpreting the results of the mathematics in terms of the original situation,
5. validating the conclusions by comparing them with the situation, and then either improving the model or, if it is acceptable,
6. reporting on the conclusions and the reasoning behind them.

In the above problem:

• Who is identifying essential variables? Where?
• Who is formulating the model for those variables? Where?
• Etc.

Additionally, many teachers have not been properly trained on the new standards many of their states have adopted, or been given proper time to review and discuss the changes to the standards, and that leads to strange questions being asked, especially in math. For example:

This does not have to be the awful question it appears to be. This is asking students to decompose numbers and then regroup. For example, the student can rewrite the problem to be 8+2+3, which would result in 10+3. Or the student can rewrite the problem to be 3+5+5, which would result in 3+10. This is a bad question because of how it's asked, but not because of the underlying math the problem is trying to get at.

The standards are not a curriculum. They are standards students are expected to meet to help to close achievement gaps and prepare them for college and the workforce. The way teachers (or schools or districts) put in place curriculum and meet those standards is entirely their own, so there is no such thing as a "Common Core math problem," just like there is no such thing as a "TEKS math problem."

It is our job to make sure the questions we're asking our students align to the standards of our states and help our students master the skills outlined in those standards. If the textbook or curriculum we have been directed to use (or have chosen to use) does not meet that criteria, it is our job to modify when necessary.

The Anatomy of a Lesson

The anatomy of a lesson has the same basic structure whether you're teaching a block schedule or a traditional schedule. Today we are going to break down the lesson into it's key components.

Lesson Planning
Planning is crucial for both types of schedules. If you have a limited time with the students, every minute must be used efficiently and purposefully. Everything from passing out materials to getting into groups must have a procedure attached to it to avoid wasted time. If you have more time with students, you still need to make sure you are using your time efficiently. If you are switching from one type of schedule to another, I highly recommend creating lesson plans that are overly detailed until you become comfortable with the new setup. Include every activity, your estimated time for each activity, how you will transition from one thing to another, and questions you plan on asking your students as well as questions you anticipate your students asking you. Once you begin to get a feel for how long everything takes, you can always scale back on your lesson plans, but it is always better to be over-prepared than under-prepared.

Set the Timer
Whether you're teaching a block schedule or a traditional (50-60 minute) class, time management is key. This is often an area where novice teachers struggle the most, but even those of us who have been in the classroom for years still have issues with timing now and again. While teaching block might seem wonderful at first (90 whole minutes to teach! They're going to learn all the things!), often teachers struggle to fill that time. They tend to allow students more down time than a teacher in a 50 minute class would, and lose out on the benefit of having the students in their classroom longer. One of the easiest things to do is time everything from the bell ringer/do now/warm-up to the instructional portion of class to independent practice to the exit ticket/closure. This will not only help your students learn how to manage their own time while working on problems, but also help keep you honest and on track. Additionally, our students have a limited attention span (about 1 minute per year of life on this planet), and changing activities frequently helps keep students engaged. Some teachers think that when they change activities it has to be something big and dramatic, but often something simple like a quick think-pair-share moment is enough.

Variety
Scheduled and structured movement around the room can be a useful way to keep the classroom moving. You can set up Math Stations, a Gallery Walk, or simply have the students change seats to take notes. Block schedules also allow for a more thorough release of responsibility to students. There is time for Direct Instruction (I do), Group Practice (We do), then Independent Practice (You do). While traditional class periods allow for all of these, teachers often have to sacrifice the amount of time spent during group practice or independent practice due to time constraints.

Transitions
All transitions from one activity to another need to be smooth, logical, and clear to students, otherwise you will lose some of them along the way. If students need to put materials away before the next activity can begin, or get materials out, assign that job to a few students. Do not give important information to students during this time. Instead, make sure that students are doing what they need to do (moving desks, passing materials forward, etc.) in order to get ready for the next thing.

Review and Closure
It is imperative that teachers leave some time at the end of class for a review of the topics or skills learned in class. This helps students bring things together in their own mind and to conceptualize what has been taught. Closure activities can be questions asked by the teacher, a think-pair-share activity, or exit tickets. Exit tickets are an excellent way to check for understanding at the end of the lesson, and can be used as a formative assessment for the lesson.

All of these are important components of any good lesson. The trick to make it a great lesson is consistency and practice. If you feel like you are struggling with any of these, observe another teacher and take notes on what they do. Even if they don't teach your grade level or your content area, you can always learn from other teachers. Best practices are best practices no matter the subject.

Number Talks Discussion #2

This is an image of a Ten Frame. These are becoming more commonly used in the lower elementary grades to help students learn how to subitize (the ability to quickly identify the number of items in a small set without counting), gain number sense, and learn about place value.

Once students become familiar with Ten Frames, they can see that this particular image shows "2 less than 10," or "5+3," or "6+2." All of these are different ways to say "8."
