At Your Request - Activity Progression Updates

As several of you have requested, I've added the assessment tools and parent letters to the Activity Progression files. I appreciate your request, since I think it will make it easier to get started by opening and using the Activity Progression files.

Subtracting from Teen Numbers

When you are getting ready to begin Goal 8 Subtraction, you may be wondering how you can help your students move beyond counting back or counting up to solve these problems using strategies based on properties of operations. I've made a Subtracting from Teen Numbers screencast that shares four different strategies that do just this. The screencast also includes a number talk approach that will provide students with time and tools to generate some or many of these strategies using logic and visuals. These four strategies will also be very relevant to Goal 9 subtraction.

You may also find you want to try this approach with Goal 5 subtraction. Relating subtraction to addition and Take from Ten may be particularly helpful for Goal 5.

I hope you and your students enjoy!
