The “Make 10” strategy is a useful mental math technique, especially when one of the addends is 9. The idea is to recognize that 9 is just one away from 10, and you can easily adjust the other addend to make a 10. Here’s how you can use the “Make 10” strategy when one addend is 9:

Problem: Add 9 and 6.

- Recognize the Relationship:

Understand that 9 is one less than 10. You’re looking for the number that, when added to 9, completes the 10. - Adjust the Other Addend:

To make a 10, subtract 1 from the other addend (6) and add to 10

9 + 6 = 10 + 5 - Write the Sum:

The sum is 15 because

10 + 5 = 15.

So, 9 + 6 can be thought of as 10 + 5 using the “Make 10” strategy.

Visualization:

You can visualize this using a number bond or a ten frame.

Note: The “Make 10” strategy can be applied in various addition problems, not just when one addend is 9. It’s a versatile method that helps simplify addition by taking advantage of the relationship between numbers.
