# Addition and Subtraction Word Match

Grade 2 students learn addition and subtraction within 100 ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29844)). This game reviews key words. Addition means putting numbers together. Sum means the answer to an addition problem. Addend means a number you add. Double means adding a number to itself ([Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)). This game also reviews compose. Compose means putting numbers together to make a new number. Inverse means using the opposite operation. Students investigate addition and subtraction within 100. Minuend means the first number in subtraction ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29850), [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)). You can make a sum in more than one way ([Understanding](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29847)).

## How to play

Look at each word on the left. Look at each meaning on the right. Draw a line to match every word to its meaning. Each word has only one correct match. Work by yourself or with a partner. Check your matches with a friend before you finish.

| Column A | | Column B |
|:---|:---:|:---|
| **A.** addition | ____ | **1.** the total |
| **B.** sum | ____ | **2.** the opposite operation |
| **C.** addend | ____ | **3.** putting together |
| **D.** double | ____ | **4.** a number plus itself |
| **E.** compose | ____ | **5.** a number made by repeated groups |
| **F.** inverse | ____ | **6.** the number being subtracted from |
| **G.** multiple | ____ | **7.** a number being added |
| **H.** minuend | ____ | **8.** to make by combining |

## Match the pairs

Use these words for your matches: addition, sum, addend, double, compose, inverse, multiple, minuend.

Think about what each word means in an addition or subtraction problem ([Guiding question](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29843), [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)). A double means adding a number to itself, like 4 + 4 ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29850)). The minuend is the top number in a subtraction problem. It is the number you start with ([Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)).

- **A** matches **3** (addition: putting together)
- **B** matches **1** (sum: the total)
- **C** matches **7** (addend: a number being added)
- **D** matches **4** (double: a number plus itself)
- **E** matches **8** (compose: to make by combining)
- **F** matches **2** (inverse: the opposite operation)
- **G** matches **5** (multiple: a number made by repeated groups)
- **H** matches **6** (minuend: the number being subtracted from)
