Subtraction can sometimes feel tricky, especially when those numbers get a little bigger. But what if I told you there’s a super cool trick that can make subtraction way easier and even fun? Get ready to learn about a strategy called “make a ten to subtract!”
This method helps break down subtraction problems into smaller, more manageable steps. Instead of being intimidated by larger numbers, you’ll be using your knowledge of making ten to simplify the problem. Once you master this, subtraction will become a breeze and your confidence will soar!
How to Master the Make a Ten to Subtract Strategy
The basic idea behind “make a ten to subtract” is to break down the number you’re subtracting into two parts. One part helps you subtract to reach ten, and the other part you subtract afterward. Think of it like taking a detour on a road trip to make the journey smoother!
Let’s say you have the problem 13 – 5. First, figure out how many you need to subtract from 13 to get to 10. In this case, it’s 3. Then, break down the 5 into 3 and 2 (because 3 + 2 = 5). So, the problem becomes 13 – 3 – 2.
Now it gets easy! 13 – 3 = 10. Then, simply subtract the remaining part: 10 – 2 = 8. Therefore, 13 – 5 = 8! See how we turned a tricky subtraction into two easier steps by focusing on making ten?
This method works especially well when subtracting from numbers between 11 and 19. The teen numbers are easier to manipulate when you can visualize breaking them down to 10 plus some extra ones. Practice it with different numbers and watch your subtraction skills improve!
The beauty of “make a ten to subtract” is that it builds a strong number sense. It reinforces the relationships between numbers and encourages mental math skills. Plus, its a fantastic strategy for children who are still developing their understanding of subtraction concepts. So, give it a try and see how much easier subtraction can become!
