# Addition and Subtraction Crossword

Grade 2 students learn addition and subtraction within 100 ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29844)). This puzzle uses math words like MINUEND, STRATEGY, and DOUBLES. You can practice these words while you play ([Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)). You will think about making a sum in many ways. You will also check your answer using inverse operations. Inverse operations means using the opposite operation ([Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)).

## How to play

Read each clue below. Think of the math word that fits. Write one letter in each white box. Some words go across. Some words go down. Shared letters connect crossing words. Use the grid to check your spelling as you go.
