Solve the addition exercise,
using two jumps on the number line below:
To solve the problem using two jumps along a number line, follow these steps:
The total increment needed to go from 81 to 98 using two jumps is .
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?
You absolutely can! But using two jumps with landmarks makes it much easier and less prone to counting errors. It's like taking rest stops on a long trip.
Pick round numbers like 90, 100, etc. that are close to your starting point. From 81, jumping to 90 first is natural because it's only 9 steps away!
That's fine! You could jump 81 → 85 → 98 (jumps of 4 and 13). As long as your total adds up to 17, any combination works.
The problem asks for two jumps specifically, but you could use more if needed. Two jumps just makes it simpler and matches what the question requests.
Always check: . If this equals the target number, you're correct! You can also verify that your two jump amounts add up to your final answer.
