Geometry: Pythagorean Theorem

Today we're tackling pythagorean theorem. Ask your child to explain the first step out loud before writing. Slow thinking now means fewer mistakes later. Encourage neat, line-by-line work. If they get stuck, ask, 'What operation is happening to the variable?' and let them lead.
