The topic Add using groups of 10 and 100 is a topic under the Early math Math Mission and 3rd grade (U.S.) Math Mission. This exercise uses the associative properties to model creative addition of integers.
Types of Problems
There is one type of problem in this exercise:
- Fill in the blanks to find sum: This problem begins with an arithmetic sum. The sum is broken down and found by utilizing several steps. The student is asked to fill in each blank with the correct number to maintain equality throughout.
Knowledge of the associative properties for addition can assist on this problem, but are not necessary. The techniques this problem practices can be used to increase general speed with addition.
- The associative property of addition states that .
- The first two blanks are always the same one digit number, but the number changes from problem to problem.
- The number "moved" or regrouped in the problem will always bring one of numbers up to a multiple of ten.
- The speed tolerances might not be fair at this time, research did problem in less than four seconds but speed badges were not yet awarded.
- Knowledge of adding and numbers are essential for algebra and the higher maths.
- Addition can be used for adding objects, like adding money totals.
- Addition is a major fundamental for higher math levels like algebra, calculus, and more.
