Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Start at the number 17 on the number line.
  • Step 2: Make the first jump of +3 +3 .
  • Step 3: Make the second jump of +4 +4 .
  • Step 4: Record the final position.

Now, let's work through each step:
Step 1: We begin at 17 and plan our jumps.
Step 2: The first jump of +3 +3 takes us from 17 to 17+3=20 17 + 3 = 20 .
Step 3: The second jump of +4 +4 takes us from 20 to 20+4=24 20 + 4 = 24 .

Therefore, the solution to the problem, using two jumps on the number line, is 24 24 .

Key Points to Remember

Essential concepts to master this topic
  • Strategy: Break down addition into smaller, manageable jumps
  • Technique: From 17, jump +3 to reach 20, then +4 to reach 24
  • Check: Verify that 3 + 4 = 7 and 17 + 7 = 24 ✓

Common Mistakes

Avoid these frequent errors
  • Adding the jump amounts incorrectly
    Don't just add 17 + 3 = 20 and stop there! This gives only a partial answer. Always complete both jumps: first 17 + 3 = 20, then 20 + 4 = 24.

FAQ

Everything you need to know about this question

Why can't I just add 17 + 7 directly?

+

You absolutely can! But this problem asks you to use two jumps to practice breaking down addition into smaller steps. This strategy helps with larger numbers later.

How do I know what size jumps to make?

+

The problem shows the jump sizes on the number line: +3 and +4. Always check that your jumps add up to the second number: 3 + 4 = 7 ✓

What if I make different sized jumps?

+

As long as your jumps add up to 7, you'll get the right answer! You could jump +2 then +5, or +1 then +6. The key is that the total equals 7.

Do I always start from the first number?

+

Yes! In 17+7 17 + 7 , you start at 17 on the number line, then make positive jumps to add the second number.

How do I show my work on the number line?

+

Draw arrows for each jump! Start at 17, draw an arrow labeled +3 to 20, then another arrow labeled +4 to 24. This shows your thinking clearly.
