A teacher is explaining a mental mathematics strategy to the class and says:
Suppose we wanted to add 76 + 9. One way to do this addition problem is to think: 76 +
9 is the same as 76 plus 10 minus 1, because 10 minus 1 is 9. By adding 76 and 10, we
get 86, then subtracting 1 gives the answer 85. This kind of thinking is also called
"making 10."
What type of strategy is being taught? CORRECT ANSWERS Compensation
