Solve the following equation,
using two jumps on the number line below:
To solve the problem of by using two jumps on the number line, we begin by identifying and making our jumps:
Add the two jumps together:
First jump: 3
Second jump: 2
Total jump:
Therefore, the value of the box () that satisfies 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 the math easier! Jumping to a round number like 90 first helps you calculate mentally without mistakes. One big jump from 87 to 92 is harder to visualize.
Since we're adding and 92 is bigger than 87, always jump to the right on the number line. Addition means moving forward (right), subtraction means moving backward (left).
Yes! You could jump to 88, 89, or 91 first, but 90 is easiest because it's the nearest round number. This makes the mental math simpler.
Add your jump sizes together: . Then check: . If both equal the target number, you're correct!
The box () represents the unknown number we need to find. It's asking: what number do we add to 87 to get 92? The answer is the total distance of our jumps.
