# Addition and Subtraction Hangman

When students work with addition and subtraction within 100 ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29844)), they learn many tools. Some words describe their thinking. They might picture a problem. They might use a **strategy** (a plan). They might find the difference between two numbers. They might regroup tens and ones to make math easier ([Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/zcsdujXlaUa2uuq1-kBv0Q)). Students investigate addition and subtraction within 100.

## How to play

One player thinks of a hidden word. The other player guesses one letter at a time. Each correct letter appears in its place. Each wrong guess adds a part to the hangman drawing. The guesser wins by finding the word before the drawing is complete. Take turns being the word keeper and the guesser.

## Puzzles
