Solve the subtraction exercise,
using two jumps on the number line below:
To solve using two jumps on the number line, we can break the subtraction into simpler steps as follows:
Thus, by performing these two jumps, we compute .
Therefore, the solution to the problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Two jumps make the subtraction easier to visualize! Instead of counting back 9 spaces one by one, we can break 9 into friendly numbers like 6 + 3 that are easier to work with.
Look for combinations that make nice round numbers! Since 46 - 6 = 40, splitting 9 into 6 + 3 works perfectly. You could also use 4 + 5 or other combinations.
That's totally fine! You could jump back 4, then 5, or jump back 1, then 8. As long as your jumps add up to 9 and go backward, you'll get the same answer: 37.
No, but number lines help you visualize what subtraction means! They're especially helpful for larger numbers or when you need to show your thinking step by step.
Absolutely! For something like , you could jump back 3 (to get 70), then jump back 12 more. Breaking into friendly numbers always helps!
