Solve the subtraction exercise,
using two jumps on the number line below:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: We start at 46 and the subtraction ends at 39, making .
Step 2: The first jump brings us to the nearest round number, 40.
Step 3: The value of this first jump is .
Step 4: The second jump brings us from 40 to 39, which is .
Step 5: Adding both jumps, .
Therefore, the solution to the problem is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
The problem specifically asks for two jumps to help you practice breaking down subtraction into easier steps. This method makes larger subtractions simpler and helps you understand place value!
Choose the nearest round number (like 10, 20, 30, 40) that's between your starting and ending points. Since we go from 46 to 39, 40 is perfect because it's close to both numbers.
Double-check your arithmetic! Make sure you calculated each jump correctly:
You could, but 40 is the smartest choice because it's the closest round number between 46 and 39. Using 50 or 30 would make your jumps unnecessarily large and harder to calculate.
Remember: subtraction means moving left on the number line (toward smaller numbers). Start at 46, jump left to 40, then jump left again to 39.
