Number Line Jumps and Operations

The video tutorial explains how to subtract using a number line. It starts by setting up the problem 543 - 275 and creating an open number line. The process involves making jumps of 100, 10, and 1 to reach the target number 543 from 275. The tutorial highlights potential difficulties students may face, such as transitioning from 495 to 505, and provides a step-by-step guide to overcome these challenges. Finally, it sums up the jumps to find the difference, which is 268.

What is the first step when subtracting using a number line?

• Write down the problem

• Draw a closed number line

• Subtract directly

• Start with the target number

What is the initial number of jumps of 100 you can make from 275?

• Two jumps
