Show how to make a ten to find 12-4. write the number sentence

Making a ten is an arithmetic evaluation strategy where students first find a way to obtain 10 from an expression before proceeding to the remainder.

Given the expression :

12 - 4

Make a ten from 12 :

12 = 10 + 2 (10 remainder 2)

Using subtracting 4 from 10 :

10 - 4 = 6

Adding the remainder (2) to the value obtained :.

6 + 2 = 8

Therefore, the direct procedure also gives the same solution ; 12 - 4 = 8.

Making tens is an strategy to help student to subtract using this number.

So, we could subtract 12-2 = 10. Now, to fins 12-4, we have to also find the way to transform the ten into 8, because 12-4=8. So, basically, by subtracting 2 units one more time we can get the 8 or 12-4; 10-2=8, and 12-4=8, therefore 10-2=12-4, which is true because 8=8.
