Solve the subtraction exercise,
using jumps on the the number line below:
To solve the subtraction problem using a number line, we will proceed with the following steps:
This process of making jumps backward clearly shows the reduction of 43 by 29, step by step. Therefore, the solution to the subtraction is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Breaking large numbers into friendly parts makes counting easier! Jumping by tens is faster and less prone to counting errors than trying to count back 29 individual spaces.
Mark your landing spots as you go! Write down 43 → 33 → 23 → 14 to keep track of each jump and avoid getting lost on the number line.
Absolutely! You could jump back 20 then 9, or 30 then forward 1. As long as the total movement equals 29 backward, you'll reach the same answer.
Add up your jump sizes! If you jumped 10+10+9, check that . The total should equal the number you're subtracting.
You can extend the number line or use tick marks to estimate positions. The important thing is maintaining equal spacing between numbers as you jump.
