Solve the subtraction exercise,
using two jumps on the number line below:
Let's solve the problem step by step.
The problem is to find the number to subtract from 74 so that the result is 38, using two jumps on a number line.
We start at 74 and need to end at 38. To do this efficiently and using the number line strategy, we break it down into two jumps:
By making these two jumps, we have:
Adding the two jumps: .
Therefore, the solution to is .
The correct choice from the options provided is 36.
In conclusion, the missing number in the subtraction is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Using two smaller jumps makes mental math easier! Jumping to a round number like 70 first helps you calculate faster and avoid mistakes.
Look for the nearest round number that's less than your starting point. From 74, jumping to 70 is easy because it's just subtracting 4!
This is a common mistake! Remember, you need the total distance traveled. Each jump shows part of the subtraction, so add them: 4 + 32 = 36.
Yes! You could jump 74 → 60 → 38 (subtract 14, then 22). As long as your jumps add up correctly: 14 + 22 = 36, you'll get the same answer.
Use the opposite operation! If , then should equal 74. Try it: 38 + 36 = 74 ✓
