This is what it looks like:
Adults do this regrouping in our heads. Kids, however, need more concrete learning. It is important to review the ways to make 10 before and during this unit (end of unit 1).
Also, kids need to practice 10 + single digit facts. They will eventually do this in their heads. (Unit 3)
This student is working on 5 + 9. He was having trouble so I pulled out some manipulatives to help him understand the process. We started with 5 yellow and 9 red. Then we moved one of the yellow hearts to the red pile to make a 10. Here he is counting the other part of 5 which is 4.
By this time we were doing the 10 + 4 in our heads.
One thing I will do differently next time is that I will mix up the 9 + facts from the beginning. They got used to seeing the same numbers in the number bond as in the answer and it isn't 11, it is the parts of 2.
Mixing them up from the beginning should eliminate them getting into this habit. Here the 5 comes first because I wanted the 1 close to the 9 to lasso it into a 10.
After working on 9 + facts. We moved to 8 + facts.
And finally 9, 8, and 7 + facts.
I am hopeful for the test tomorrow!
