# Addition and Subtraction Matching Game

In Grade 2, students investigate addition and subtraction within 100 ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29844)). This game helps you match key words and ideas to their meanings. You will work with addends, sums, and the numbers we subtract from, called the minuend ([Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29852)). You will also explore doubles and how to compose a sum in more than one way ([Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29848)). Understanding these terms helps you become stronger at addition and subtraction strategies ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/29850)).

## How to play

1. Look at the words and definitions on your sheet.
2. Draw a line to match each word on the left to its meaning on the right.
3. Work carefully. Each word matches to exactly one meaning.
4. Check your work with a partner or your teacher when you finish.

## Match the pairs

| Column A | | Column B |
|:---|:---:|:---|
| **A.** addend | ____ | **1.** 7 in 7 − 3 = 4 |
| **B.** sum | ____ | **2.** 6 + 6 = 12 |
| **C.** subtract | ____ | **3.** 7 − 3 = 4 |
| **D.** compose | ____ | **4.** 5 apples or 10 centimetres |
| **E.** inverse | ____ | **5.** 8 in 3 + 5 = 8 |
| **F.** doubles | ____ | **6.** 3 in 3 + 5 = 8 |
| **G.** minuend | ____ | **7.** 5 + 5 and 6 + 4 both make 10 |
| **H.** quantity | ____ | **8.** If 5 + 3 = 8, then 8 − 3 = 5 |

## Answer key

- **A** matches **6** (addend: 3 in 3 + 5 = 8)
- **B** matches **5** (sum: 8 in 3 + 5 = 8)
- **C** matches **3** (subtract: 7 − 3 = 4)
- **D** matches **7** (compose: 5 + 5 and 6 + 4 both make 10)
- **E** matches **8** (inverse: If 5 + 3 = 8, then 8 − 3 = 5)
- **F** matches **2** (doubles: 6 + 6 = 12)
- **G** matches **1** (minuend: 7 in 7 − 3 = 4)
- **H** matches **4** (quantity: 5 apples or 10 centimetres)
