There are a number of ways to approach this problem. Before we look at them, let's define each term of the addition problem. 
43 and 9 are both called addends.
The answer to the problem (52 in our case) is called the sum.

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?]
