2. Regrouping To arrange in a new grouping

3. Let’s review addition without regrouping. Our total was not 10 or more so we didn’t have to regroup. +

4. Addition with regrouping is used when our answer is 10 or more. We can only put 9 ones in the ones place. So a 10 is equal to 1 group of ten and 0 ones.

5. TensOnes

6. Four ones plus eight ones equal twelve ones in all. 4 ones + 8 ones 4 + 8 12 12 ones in all

7. We can regroup the 12 ones as 1 tens and 2 ones. 1 tens 2 ones 4 + 8 12

8. 4 +8 12 4 + 8 is equal to more than 9 so we had to regroup. and 2 in the ones place. We regrouped the 12 ones as 1 in the tens place

9. Let’s try with two digits

10. Twenty nine ones plus 4 ones equal 33 ones in all. 2 tens 9 ones + 4 ones 29 + 4 = 33 ones in all

11. We can regroup the 33 ones as 10 ones and 1 ones. 2 9 + 4 = 33 3 tens 3 ones

12. We can regroup the 10 ones as 4 group of ten and 1 one. 5 ones3 tens 6 ones 36+ 5 = +

13. 36 + 5 = 41 36 + 5 is equal to more than 9 so we had to regroup. and 1 in the ones place. We regrouped the 10 ones as 4 in the tens place
