The students are to arrange the Cuisenaire rods into a shape on the centimeter paper. It is necessary that when the student traces around their shape, they draw only on the black lines and their shape must remain in one piece if it were to be cut out. The students must find a way to arrange the rods in order to make the smallest and largest possible perimeter. Have them trace their shapes and count the perimeter of each before making the next one. To add an extra challenge, increase the number of Cuisenaire rods.
Students can work in groups or individually.
