How to show the tens fact you used. write the difference. 14-6=_ 10-=__
The Correct Answer and Explanation is:
To show the tens fact you used and write the difference for:
14 – 6 = ___
10 – ___ = ___
Correct Answer:
14 – 6 = 8
10 – 6 = 4
Explanation
When solving subtraction problems such as 14 – 6, using a tens fact can help break the problem into smaller, easier steps. A tens fact is a subtraction or addition fact based on the number 10. This method helps young learners become more confident by connecting difficult problems to simpler ones they already know.
Let’s break it down:
We start with 14 – 6. The number 14 is greater than 10, so we can think of it as 10 + 4. That helps us visualize the problem better.
Now, subtract 6 from 14 by first subtracting from 10 and then adjusting for the rest.
So:
- Start with 14.
- Think of it as 10 + 4.
- Subtract 6 from 10, which gives 4.
- But we still have the extra 4 that was part of 14.
- Now, add that 4 back to the result from 10 – 6.
That is:
- 10 – 6 = 4
- 4 (from the 14) + 4 (the result of 10 – 6) = 8
So:
- 14 – 6 = 8
We used 10 – 6 = 4 as the tens fact to help us find the answer.
This approach shows how subtracting from 10 can guide us in solving more complex subtraction problems. It’s especially useful for mental math because it reduces the steps and relies on facts many students already know. Over time, using this strategy builds number sense and improves accuracy and speed in basic arithmetic.
