Question

Sally add 9 to 27. explain how she can use the make 10 strategy to solve the problem.

Answer 1

the answer is 36 what is the make 10 strategy

Answer 2

If we add two numbers or more than two numbers then make ten strategy is a basic strategy to learn addition .

In this strategy we break the smaller number in terms to make the larger number equals to ten or tens .

For example :-

`8+7=8+(2+5)=8+2+5=10+5=15`

Now, the given addition problem is
`9+27`

Here we break 9 to make 27 equals to 30 or 3 tens.

We can write,
`9=6+3`

Such that
`9+27=(6+3)+27=6+3+27=6+(3+27)=6+30=36`

hence,
`9+27=36`
