Question

Use the ten-frame and a crayon to show how to decompose the numbers into tens and ones

Answer 1

• 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
