Five pages on rectilinear shapes: shapes made of two rectangles, like an L or a T. On page 1 the shapes are on a grid with the split already drawn and the two parts shaded differently. Page 2 is on a grid too, but students draw the split line. Page 3 gives side lengths with the split drawn, and page 4 gives side lengths only, so students work out the length of each part. Page 5 has four floor plans and garden plans to solve.
Cut an L shape from grid paper and let students show two different ways to split it into rectangles. Both ways give the same area, which is a good discussion to have before page 2.
Sketch a room in your home that is not a plain rectangle and ask your child to split it into rectangles. Count or multiply to find the area of each part.
