# Choose Math Operation Game

*Choose Math Operation* is a fun game for all children (and adults) where you need to find the operations that are missing from the given number sentence, such as 12 ? 5 = 60. It is a useful tool for developing number sense, practicing the role of one and zero within different math operations, understanding the order of operations, practicing the basic operations with negative numbers - and just to develop logical thinking.

The goal is to get the fish flop up the ten steps of the stairs. If you answer right, the fish flops one step up, and if you answer wrong, the fish flops one step down (unless you're already on the bottom step)!

First you need to select between two modes of the game:

(1) Choose one operation (easier)

(2) Choose two operations (harder)

## Choose one operation

### Instructions

You are given a mathematical sentence that lacks the operation, such as:

4 ? 10 = 40

The goal is to get the fish flop up the ten steps of the stairs. If you answer right, the fish flops one step up, and if you answer wrong, the fish flops one step down (unless you're already on the bottom step)!

The operation is one of the four basic operations: addition, subtraction, multiplication, or division. All the numbers involved are integers within the range you specify.

### Ideas on how to use this game

- Kindergarten, first, and second grader students can practice the difference between addition and subtraction: Use an appropriate number range and tick the box "Use only addition/subtraction".
- Third and fourth graders can practice the roles of 0 and 1 in addition, subtraction, multiplication, and division: Set the range to be relatively small, for example from 0 to 30. This will force the game to use the numbers 0 and 1 more often than if you choose a wider range.
- Set the range to be for example from 0 to 200 to allow elementary school children to develop number sense, logical thinking, and a good understanding of the basic operations.
- Middle school students can practice operations with integers: Choose a range involving some negative numbers, for example from -20 to 50.

## Choose two operations

### Instructions

You are given a mathematical sentence that lacks two operations, such as:

100 ? 5 ? 2 = 40

The goal is to get the fish flop up the ten steps of the stairs. If you answer right, the fish flops one step up, and if you answer wrong, the fish flops one step down (unless you're already on the bottom step)!

The operations to use are the four basic operations: addition, subtraction, multiplication, or division. All the numbers involved are integers within the range you specify.

You need to take into account the proper order of operations. In this game, parentheses are not used, so multiplication/division is done before addition/subtraction. For example,

5 __ 4 __ 7 = 33

is solved by 5 + 4 × 7 = 33.

### Ideas on how to use this game

- For elementary grades: choose addition/subtraction and a fairly large number range to develop number sense with large numbers.
- From all grades: develop number sense, logical thinking, and good understanding of basic operations.
- For middle & high school: choose a range that involves negative numbers to let students practice the basic operations with negative numbers.
