|Exercise Name:||Repeated addition|
|Math Missions:||Early math Math Mission|
|Types of Problems:||2|
The first instance of the Repeated addition exercise is under the Early math Math Mission. This exercise helps users see how multiplication piggy-backs off of addition through adding the same quantity multiple times.
Types of problems
There are two types of problems that show up in this exercise:
- Select expressions that count objects: This problem has a pictured collection of objects arranged in rows and columns. The user is to select the correct expressions that represent the total number of objects in the collection.
- Select expressions that describe situation: This problem describes a situation, often accompanied by a chart. The user is to answer the question by selecting the expressions that evaluate to the answer to the problem.
- Most problems have two answers, adding the higher number of small groups and adding the smaller number of large groups. For example, .
- The exception to the previous hint is when the number is a perfect square and you have the same number of groups as the size of the groups. In this case, there is only one solution.
- Repeated addition is just multiplication.
- 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.
