This lesson illustrates how single-digit sums going over 10 can be used when adding a two-digit number and a single-digit number. For example, knowing what 7 + 8 is helps us add 37 + 8.

1. Fill the missing addends.

If 8 + __ = 10, then 8 + __ = 11.	If 6 + __ = 10, then 6 + __ = 11.	If 3 + __ = 10, then 3 + __ = 11.
We need just _____ more to make eleven than to make a ten!

2. What if we already have some tens? Circle the little cubes like above to make a ten. Add.

13 + 9 = ___

15 + 8 = ___

17 + 7 = ___

24 + 7 = ___

25 + 6 = ___

37 + 9 = ___

When the ones in the problem go over ten, the answer goes to the next ten.

3. Continue the patterns. COMPARE the columns.

8 + 1 = __

8 + 2 = __

8 + 3 = __

8 + 4 = __

8 + __ = __

28 + 1 = __

28 + 2 = __

28 + 3 = __

28 + 4 = __

28 + __ = __

6 + 2 = __

6 + 3 = __

6 + 4 = __

6 + __ = __

__ + __ = __

36 + 2 = __

36 + 3 = __

36 + 4 = __

36 + __ = __

__ + __ = __

What is same? What is different?

4. Add. Compare the problems!

7 + 8 = __

17 + 8 = __

27 + 8 = __

37 + 8 = __

4 + 9 = __

14 + 9 = __

24 + 9 = __

44 + 9 = __

7 + 9 = __

17 + 9 = __

57 + 9 = __

37 + 9 = __

What is same? What is different?

5 + 6 = __

15 + 6 = __

75 + 6 = __

25 + 6 = __

8 + 8 = __

18 + 8 = __

58 + 8 = __

88 + 8 = __

7 + 5 = __

17 + 5 = __

47 + 5 = __

27 + 5 = __

5. Add. For each problem, write the corresponding problem with just the ones digits.

46 + 3 = __

6 + 3 = 9

32 + 7 = __

__ + __ = __

63 + 8 = __

__ + __ = __

19 + 5 = __

__ + __ = __
