Answer:
- 1 Suppose these numbers are boxes and the dots
- 2 represent the crayon color to show that they are filled.
- 3 If we have 1 ten frame we will use it one ten and if we have
- 4 5 ones then they will not be a ten. 2 tens would make a
- 5 twenty similarly 3 tens would make a thirty.
- 6
- 7
- 8
- 9
- 10
- 1 If we add a single 10 and 5 ones the answer would be 15
- 2 Other examples would adding two tens and 7 ones which
- 3 would make 27.
- 4
- 5
Another way to decompose the number would be
43 taking the 4 of the left with tens like 40 ( 4*10) and 3 of the right as three separate ones ( 3*1= 3) .Adding 10s four times with three one times would make 43
