Making a ten is a strategy to simplify addition, especially with larger numbers. Instead of directly adding two numbers, you break one number down to make the other number a ten. For example, to add 9 + 6, you can break down 6 into 1 + 5. Then, add 1 to 9 to make 10, and finally add the remaining 5 to get 15. This method makes mental math much easier!
This strategy is super useful because adding to 10 is very easy for most people. By converting addition problems into simpler forms based on 10, we can solve them more quickly and accurately. Let's get started with the worksheet!
| Term | Definition |
|---|---|
| 1. Addend | a. The result of addition |
| 2. Sum | b. Breaking down a number |
| 3. Decompose | c. A strategy to simplify addition |
| 4. Making a Ten | d. Numbers that are added together |
| 5. Number Bond | e. A visual representation of how numbers can be broken apart and combined |
Match the term with its correct definition.
To use the 'making a ten' strategy, we first _________ one of the addends. Next, we find out what number we need to add to the other addend to make _________. After making ten, we add the _________ part of the decomposed number to ten to find the final _________. This method simplifies addition and makes it _________ to solve problems.
Explain in your own words how 'making a ten' helps you add numbers faster and more accurately. Can you think of a real-life situation where this strategy might be useful?
