4.MD.3 – Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
Samples: Calculating Perimeter Regular Shapes. Challenge puzzle -perimeter. Area. Area in daily use.
5.NF.4 – Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
5.NF.4.b – Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.
