Given a rectangle with whole number length sides, Find and justify the area of the rectangle by relating a tile covered model to a corresponding multiplication problem (counting unit squares in rows and columns compared to multiplying length by width). Using array cards or tiles, Create and explain rectangular models to show that the area of a rectangle with side lengths a and d (where d=b+c) is the same as the area of two smaller rectangles with area a x b and a x c. (the Distributive Property). Strategies for finding sums and products of whole numbers. Model the area of rectangles using manipulatives or graph paper, Strategically and fluently choose strategies for finding sums and products, Accurately compute sums and products. The area of a plane figure is measured by the number of same-size squares that exactly cover the interior space of the figure, Multiplication is putting together equal sized groups, Rectangular arrays represent groups (rows) of equal size (number of columns), Multiplication is distributive over the addition of whole numbers.
