Starter- I’m thinking if a number.
My number is 3 more than 7. What is my number? 10
My number is 5 more than 5. What is my number? 10
My number is 6 more than 4. What is my number? 10
My number is 10 more than 3. What is my number? 13
My number is 9 more than 5. What is my number? 14
My number is 4 less than 14. What is my number? 10
Here are 3 number cards. Can you give me four equations you can make using these numbers? 4, 7, 3
One has been done for you.
4 + 3 = 7
3 + 4 = 7
7 = 3 + 4
7 = 4 + 3
Here are 3 number cards. Can you give me four equations you can make using these numbers? 9, 1, 10
9 + 1 = 10
1 + 9 = 10
10 = 9 + 1
10 = 1 + 9
Here are 3 number cards. Can you give me four equations you can make using these numbers? 5, 13, 8
8 + 5 = 13
5 + 8 = 13
13 = 8 + 5
13 = 5 + 8
Challenge
Which calculation is the odd one out in the group of equations?
| 2 + 3 = 5 |
| 3 + 2 = 5 |
| 3 = 5 + 2 |
| 5 = 3 + 2 |
| 7 + 1 = 8 |
| 8 + 1 = 7 |
| 8 = 7 + 1 |
| 8 = 1 + 7 |
| 4 + 10 = 6 |
| 6 + 4 = 10 |
| 10 = 6 + 4 |
| 10 = 4 + 6 |
Extra challenge.
Draw models to match the following equations.
6 + 4 = 10
5 + 3 = 8
7 + 7 = 14
