Activities provide manipulatives such as straws or sticks for sides and chanelle sticks (small segments to fit into ends of straws) or globs of plasticine for angle "joiners." They ask children to build accurate models of various shapes, discussing for example, that the four sticks need to be the same length to make a rhombus, and if they want that rhombus to also be a square, all angles have to be right angles.
