Finding the Difference in Length

The video tutorial teaches how to measure and compare the lengths of objects using non-standard units like paper clips and cubes. It emphasizes the importance of using consistent unit sizes for accurate comparison. Through examples, such as measuring a pencil and a toy car, and a baseball bat with its cover, the tutorial demonstrates how to find the difference in length between objects. The key takeaway is understanding that consistent measurement units are essential for accurate length comparison.

Why is it important to use the same size units when measuring objects?

• To ensure the measurements are accurate and comparable

• To make the objects look bigger

• To save time during measurement

• To use fewer units

If a pencil is 3 paper clips long and a toy car is 2 paper clips long, how can we describe their lengths?

• The car is 2 paper clips longer than the pencil

• The pencil is 1 paper clip longer than the car

• The car is 1 paper clip longer than the pencil

• The pencil is 1 paper clip shorter than the car

What is the difference in length between a toy car and a pencil if the pencil uses one more paper clip?

• 2 paper clips

• 3 paper clips

• 1 paper clip

• No difference

In the example with the baseball bat, how many cubes longer is the cover compared to the bat?

• 4 cubes

• 1 cube

• 3 cubes

• 2 cubes

Will the baseball bat fit into its cover if the cover is 2 cubes longer?

• Yes, because the bat is longer

• Yes, because the cover is longer

• No, because the bat is longer

• No, because the cover is shorter
