Addition Strategies: Using Doubles
Recall the doubles facts.
| 1 + 1 = 2 | 6 + 6 = 12 |
| 2 + 2 = 4 | 7 + 7 = 14 |
| 3 + 3 = 6 | 8 + 8 = 16 |
| 4 + 4 = 8 | 9 + 9 = 18 |
| 5 + 5 = 10 | 10 + 10 = 20 |
Let's find the numbers whose doubles can be used to add 4 and 5.
Add 4 and 5 using doubles plus one strategy.
4 + 5 = 4 + 4 + 1 = Double of 4 + 1 = 8 + 1 = 9
Now, let’s add 4 and 5 using doubles minus one strategy.
4 + 5 = 5 + 5 – 1 = Double of 5 – 1 = 10 – 1 = 9
So, doubles of 4 and 5 can be used to add 4 and 5.
