reSolve: Reasoning with 2D Shapes

This sequence of three lessons explores shape properties and skills in manipulating shapes using transformations. Students create two-dimensional shapes by joining pins on a circular geoboard, explore the different shapes that can be made by joining together a set number of identical equilateral triangles and investigate the different tetrominoes that can be made by joining together four squares. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, discussion points and student resources such as templates. This sequence is part of the reSolve: Mathematics by Inquiry program.
