Quadrilaterals and Their Attributes: how to help at home or in class
Draw a big loop labeled quadrilaterals and place smaller loops inside it for rectangles and rhombuses, overlapping. Ask where a square belongs and why. Check right angles by fitting the corner of a sticky note into each corner, and compare side lengths with a ruler. When your child can explain, in words, why every square is a rectangle but not every rectangle is a square, move on to perimeter.
