Subtracting Doubles Reflection

During this lesson the students really understood how many different strategies they could use to solve the subtraction problem.  Many students are comfortable using a number line or hundred chart as their go-to resource to help them solve the addition and subtraction problems.  It is my goal to get them to use those as mental models. But it is important for them to understand that they can use other strategies, such as thinking about the related addition problem, to help them solve subtraction facts

Don't Assume!

I was really surprised to see the different strategies students used to find the "1" on the yarn number line.  I started with that, assuming that they would simply fold the yarn in half and mark the spot with a 1, just as we did with our paper fraction strips.  

However, only one group did that right away.  Some tried a "guess and check", by placing a finger where they thought the middle was, and then folding to see if both sides were the same.  Another team asked for a yard stick so they could measure and divide.  One group just eyeballed it!

I am constantly reminded why simple, yet powerful, tasks like these are necessary.  When students are truly asked to apply what they know and use teamwork to accomplish a task, I rediscover that I should never assume that I know what they know based on work on a paper.  Seeing them in action and listening to their discussion is the authentic assessment of their knowledge.
