The topic Making small numbers in different ways is a topic under the Early math Math Mission. This exercise practices alternative ways to sum numbers to a given total and can give motivation for later regrouping.
Types of Problems
There are two types of problems in this exercise:
- Find alternative ways to the total: This problem provides a number of objects in a picture. The user is asked to fill in two blanks that can represent the sum in two different ways.
- Use the visual aid to regroup: This problem is very similar to the above problem. The problem again provides a group of objects that is to be split in alternative ways. The only difference is that the groups are given a visual representation.
Strategies
Interpreting the visual aid and thinking of numbers as quantity can help on this problem but are not necessary.
- users that have higher math experience, specifically with borrowing and carrying, can use this to help with the problem.
Real-life Applications
- 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.
