What children learn in Level 18
- A double is a number added to itself, like 3 plus 3. Two rows, the same size!
- Doubles are all around us. 5 fingers on each hand: 5 plus 5 is 10.
- A spider has 4 legs on each side: 4 plus 4 is 8.
- Here are the doubles to 10: 1 plus 1 is 2. 2 plus 2 is 4. 3 plus 3 is 6. 4 plus 4 is 8. 5 plus 5 is 10.
- Doubles are easy to remember. Soon you'll just know them!
