Think about the number bonds that create the number 29.

Next, solve the following problem:

22 + _____ = 29

You can take a shortcut and start from 20.

20+9=29

21+8=29

22+7=29

You can stop here because you found the answer.

22+7=29. 7 is the answer.

So, if

22+7=29

then,

7+22=29

and

29-22=7

29-7=22

Think about the number bonds that create the number 11.

Next, solve the following problem:

5 + _____ =11

You can start from 1: 1+10=11; 2+9=11; 3+8=11; 4+7=11; 5+6=11

You can stop here because you found the answer.

5+6=11

6 is the answer.

So, if 5+6=11 then, 6+5=11 and 11-5=6 and11-6=5

Think about the number bonds that create the number 19.

Next, solve the following problem:

13 + _____ = 19

You can start from 10: 10+9=19; 11+8=19; 12+7=19; 13+6=19

You can stop here because you found the answer: 13+6=19

6 is the answer.

So, if 13+6=19 then, 6+13=19 and 19-13=6 and 19-6=13

Solve:

32 + _____ = 45

Think about the number bonds for 45.

You can start with: 30+15=45; 31+14=45; 32+13=45

You can stop here because you found the answer: 32+13=45.

13 is the answer.

Or you can subtract: 45-32=13

Solve:

8 + _____ = 15

Think about the number bonds for 15.

You can start with:

5+10=15

6+9=15

7+8=15

You can stop here. Even in reversed order, we can see that 7 is the answer.

7+8=15

and

8+7=15

Or you can subtract to find and check your answer:

15-8=7

15-7=8
