Addition
What is addition?
Addition means putting groups together to find the total. We use the plus sign (+) and the equals sign (=).
Number sentence
3 + 2 = 5
- 3 and 2 are the numbers being added.
- 5 is the answer, called the sum or total.
Using objects
3 mangoes and 2 mangoes together make 5 mangoes.
Counting on with a number line
To add 6 + 3, start at 6 and jump 3 steps: 7, 8, 9. So 6 + 3 = 9.
Helpful facts
- Adding 0 does not change a number: 5 + 0 = 5.
- Order does not matter: 2 + 4 = 4 + 2 = 6.
Try it
- 5 + 4 = ?
- 7 + 3 = ?
- Ali has 6 marbles and gets 2 more. How many has he now?
