Provide the students with a piece of paper that has a lot of dotted rectangles on it and the word rectangle in dotted writing at the top. They should trace over the word and the shape outlines with different coloured pencils or crayons. Then they can use each rectangle to draw an object that has a rectangular shape, eg a TV, a mobile phone, a book, a ruler, and so on. Make it! Give each student some playdough, plasticine or clay to make a rectangle.
