Solve the addition exercise,
using two jumps on the number line below:
To solve the given problem, we need to find the missing number that, when added to 15, equals 37. We'll use a number line approach that involves taking two jumps.
First, we'll make a jump from 15 to the next round (friendly) number, which is 20. This first jump is:
Next, we'll make a second jump from 20 to 37. This second jump is:
Now, we'll add these two jumps together to find the total increase from 15 to 37:
Thus, the value of the missing number is .
Therefore, the solution to the problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Making two jumps helps you visualize the addition process and makes mental math easier! Jumping to a round number like 20 first gives you a friendly landmark to work from.
Choose the nearest multiple of 10 that's bigger than your starting number. From 15, the next friendly number is 20, which makes the first jump easy to calculate.
Double-check your jumps! Make sure your first jump goes from 15 to exactly 20 , and your second jump goes from 20 to exactly 37 .
Absolutely! This two-jump strategy works great for any addition where you need to find a missing number. Just find a friendly number between your start and end points.
Yes, you can subtract: . But using the number line method helps you understand what addition really means and builds stronger mental math skills!
