Understanding Measurement with Rectangles and Centimeters

The video tutorial explains how to measure lines using rectangles and centimeters. It demonstrates that a rectangle is longer than a centimeter, leading to fewer rectangles needed to measure the same line compared to centimeters. The tutorial provides examples with green and blue lines, showing the conversion between rectangle lengths and centimeters.

How long is the green line when measured in rectangles?

• Four rectangles

• Three rectangles

• Two rectangles

• One rectangle
