# Addition and Subtraction Within 100

In Grade 2, students investigate addition and subtraction within 100 ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29844)). This word search helps you practise the language of addition and subtraction. You will find words like ADDING, DOUBLE, MISSING, and PATTERN as you search the grid. Understanding this concept reinforces that the order in which more than two numbers are added does not affect the sum([Details](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29846)).

## How to play

- Read each word in the word list below.
- Search the grid left to right, top to bottom, and diagonally.
