Students must be able to find the area of rectangles in problems based on the number of rows and number of square units in a row, using multiplication.
Remy’s family wants to turn their outdoor patio into an indoor sunroom. Part of the plan calls for covering the concrete slab with carpet squares that are 1 foot long on each side.
Based on the illustration below, how many carpet squares are needed to cover the slab? Explain how you determined the number of squares they needed.

3.6 Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional geometric figures to develop generalizations about their properties. The student is expected to:
(C) determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row
