For all ages, activity guide covers from elementary school through middle school, high school up to Einsteins proof of the famous Pythangorean Theorem Kit contains 7 piece puzzle that has the ability to do multiple proofs and instruction guide DIY assembly and proof solving Instruction guide has segmented sections for each appropriate age level (A^2) + (B^2) = (C^2) We?™ve designed this kit to enable an engaging back and forth for almost every level of child. Young children can use the kit to explore basic shapes and similarity. Elementary-school children can engage in solving the central puzzle of the Pythagorean theorem - forming squares that represent the squares of the hypotenuse and shorter sides. Middle-school students can use the puzzle to work out three algebraic proofs of the Pythagorean theorem, including the proof put forward by President James A. Garfield. High-school students can use the kit to explore units of measure and reason out Einstein?™s proof of the Pythagorean theorem. Here we provide suggestions on how to engage with each of these age-groups!
