Solve the subtraction exercise,
using two jumps,
on the number line below:
To solve the problem using a number line, we'll break the subtraction into two smaller steps. This method can help by using round numbers and ensuring accuracy:
First Jump:
Second Jump:
This gives us the final solution of .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
The problem specifically asks for two jumps to practice the decomposition strategy. This helps you break down harder subtractions into easier steps using friendly numbers like multiples of 10.
Look for a way to reach a round number first! Since 92 is close to 90, subtract 2 first. Then subtract the remaining amount (5) to finish the problem.
Try breaking the subtrahend into smaller, easier numbers. For 7, you could use 2+5, 3+4, or 1+6. Pick whichever feels most comfortable to you!
While you could make more jumps, this exercise specifically asks for two jumps to practice efficient decomposition. Learning to use fewer, strategic jumps makes subtraction faster!
Always check that your jumps add up to the original subtrahend. In this case: 2 + 5 = 7 ✓. Also verify your final answer: ✓
