Solve the addition exercise,
using two jumps on the number line below:
To solve the problem using the number line, we will make strategic jumps:
First, jump from 33 to the nearest higher round number, which is 40:
Next, jump from 40 to 42:
Add the two jumps to find :
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?
Using two strategic jumps makes counting easier! Jumping to round numbers like 40 first helps you break big problems into smaller, manageable steps.
You could jump to other numbers, but round numbers like 40 make mental math much easier. Try different strategies and see which feels most comfortable!
Since we're adding to 33 to get 42, we always move to the right (toward larger numbers) on the number line.
Yes! You can use subtraction: . But the number line helps you visualize the problem and understand what addition really means.
Double-check your counting! Make sure your first jump lands exactly on your chosen middle number, then count carefully for the second jump. Practice makes perfect!
