Your teacher has posted images of rectangles around the room. Match each expression with a rectangle that can represent it. Be prepared to explain your reasoning.
9 x 5
8 x 2
The numbers in each expression represent the number of rows (or columns) in a rectangle and how many squares are in each row (or column).
On the grid, draw each rectangle, label it with the numbers, and find its area.
3 x 4
On the grid, draw each rectangle, label it with the numbers, and find its area.
4 x 6
Use the grid to create a rectangular area that represents the expression 7 x 4.
Explain your reasoning.
