This week in math, we'll be focusing on using a variety of strategies to solve 2-digit addition problems. It is important that our students try to use the different strategies, then determine which will work best for them. We are NOT teaching students the traditional algorithm of carrying and regrouping. We'd like them to build a deeper understanding of the concept through the use of some of the strategies listed below:
Example problem: 47 + 35
Number line- Start at 47 than skip count 3 tens and a five
tens + tens, ones+ ones
40 + 30 = 70
7 + 5 = 12
70 +12 = 82
Ask your children to share some of the new strategies that they've learned!
