Squares are so cool ... they get into every club! I explain to my students that squares are in the parallelogram club, the rhombus club and the rectangle club. This really helps the kids understand some complicated geometric nomenclature.
shapes are fat not flat. A cone is like a party hat. A sphere is a bouncing ball. A prism is a building tall. A cylinder is like a can of pop. A cube is like a dice you drop. shapes are here and there. shapes are everywhere.
