Addends are the numbers that we use to add together to get a bigger number. For example, in the number sentence 2 + 3 = 5, the addends are 2 and 3.

On this worksheet, you will see some number sentences that are not true yet. Your job is to figure out what number you need to add to make the number sentence true. Then, you will write that number in the box provided.

**Let’s look at an example:**

3 + ___ = 7

To figure out what number we need to add to 3 to make 7, we can count on from 3: 4, 5, 6, 7. So the number we need to add is 4. We write 4 in the box to make the number sentence true:

3 + 4 = 7

Now it’s your turn! Try to figure out what number you need to add to make the number sentence true, and write it in the box provided. Remember, you can count on the first number to figure out what number you need to add. Good luck!
