Solve the addition exercise,
using two jumps on the number line below:
To solve the equation using two jumps on a number line, we will take the following approach:
Now, let's calculate each step:
Step 1: The first jump from 24 to 30 is 6 units.
Step 2: From 30 to 45, the jump is 15 units.
Adding these two jumps: .
Therefore, the number that completes the equation is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Using two jumps makes large differences easier to calculate! Instead of counting from 24 to 45 one by one, we jump to a round number (like 30) first, then complete the journey.
Jump to the nearest round number that's higher than your starting point. From 24, the closest round number is 30, making the first jump easy to calculate (24 + 6 = 30).
That's normal! The jumps don't have to be equal. Just make sure each jump calculation is correct:
Use substitution! Replace the box with your answer: . If both sides equal the same number, you're correct!
Yes! The two-jump strategy works especially well when you have larger numbers. Always jump to round numbers (like 10, 20, 30) to make calculations easier.
