# Addition and Subtraction Hangman

In this game, you guess letters to reveal hidden words about addition and subtraction. All the words you will find relate to ways we work with numbers and compare quantities ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29844)). When you play, you will think about how we combine numbers, notice patterns, and understand what it means to compare amounts. 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

You have six wrong guesses before the game ends. Each round shows you a word with blank spaces. Guess one letter at a time. If the letter appears in the word, it fills in every space where that letter belongs. If the letter does not appear, you lose one guess. Guess all the letters and reveal the word to win the round. Try all four words.
