Warm-up Estimation Exploration: How Much is Shaded?
What is the area of the shaded region?
Record an estimate that is:
Activity 1 Notice Patterns in Expressions
Choose one of the diagrams and write a multiplication expression to represent the shaded region. How much of the whole square is shaded? Explain or show your thinking.
If the pattern continues, draw what you think the next diagram will look like. Be prepared to explain your thinking.
Activity 2 Write a Multiplication Equation
Write a multiplication equation to represent the area of the shaded piece.
Explain how the diagram represents the equation
Find the value that makes each equation true. Use a diagram, if it is helpful.
Write an equation representing the shaded part of the diagram.
Explain how the diagram shows each part of your equation.
