I have created an combined group of addition strategies that has really helped some of my kids. In AMSTI we teach them so many different ways to add numbers, they often forget one or two by the second semester. So I put them all together in one pack. I did go back and create anchor charts for each of the strategies. Here are three of them.
These serve as a great reminder to all my students about the different strategies we have learned all year. Visit my store on TeachersPayTeachers to check out this pack.
