To solve the subtraction problem using two jumps on a number line, we will follow these steps:
Now, let's work through each step:
Step 1: Start at 74. We need to subtract 8 in total. We begin by subtracting 4.
Step 2: From 74, subtract 4 to get the intermediate value. .
Step 3: Subtract the remaining 4 (totaling 8) from the intermediate value of 70. Thus, .
Therefore, the final result of is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
You absolutely can! The two-jump method is just a strategy to make subtraction easier by breaking it into smaller, more manageable steps. It's especially helpful with larger numbers.
Look for friendly numbers that are easy to work with! For subtracting 8, you could use 4+4, or 5+3, or even 10-2. Choose what feels most comfortable to you.
That's perfectly fine! You could do 74 - 6 = 68, then 68 - 2 = 66. As long as your jumps add up to 8 total, you'll get the right answer.
Not at all! The example uses for simplicity, but you could use any combination that adds to 8, like or .
Add up your jump amounts: they should equal the original number you're subtracting. Then add your answer back to the original number to verify: ✓
