Question

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

Answer 1

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
