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.

## Strategies

The accuracy badges are fairly easy here, but the speed badges are medium difficulty because of the needed multiple selection.

- 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.

## 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.
