Problem Solving with Measurement: Drawing Models to Find the Unknown

This video tutorial teaches how to solve measurement problems by drawing models to find unknowns. It covers the relationship between multiplication and division, using bar models for visualization, and provides examples like wire cutting and ribbon problems. The tutorial emphasizes understanding given information and setting up problems with total length, number of pieces, or size of each piece.

What is the relationship between multiplication and division?

• Division is always larger than multiplication.

• Multiplication is the inverse of division.

• They are both used to add numbers.

• They are unrelated operations.

What is a common misunderstanding when visualizing word problems?

• Thinking that bar models are slower.

• Believing that multiplication is not related to division.

• Assuming all problems are addition problems.

• Forgetting to use a calculator.

In the wire cutting problem, what is the unknown we are trying to find?

• The number of pieces.

• The color of the wire.

• The size of each piece.

• The total length of the wire.

How many feet long was each piece of wire in the example?

• 3 feet

• 6 feet

• 4 feet

• 5 feet

In the ribbon problem, what is the total length of the ribbon?

• 24 inches

• 48 inches

• 56 inches

• 32 inches

How many bows can Melinda make from the ribbon?

• 5 bows

• 7 bows

• 6 bows

• 4 bows

What symbol is used to represent bows in the ribbon problem?

• R

• W

• B

• P
