In this practical task, students make different shapes with four multi-link cubes, draw them, identify the smallest perimeter, and explain what happens to the area.
Students write the simplest algebraic expressions for the lengths and area of parts of a composite shape, then solve these expressions using substitution. They then solve an equation that relates an algebraic expression to a given side length.
Students calculate the number of 2cm blocks fit into a given 3-dimensional block model, and answer questions about one face, and volume of the block model.
