reSolve: Reasoning with 3D Objects

This sequence of lessons explores symmetry and three-dimensional objects. Students interpret and represent three-dimensional objects in two dimensions and apply their knowledge of transformations to show congruency or difference between objects. The lessons are outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and PowerPoint slides. This sequence is part of the reSolve: Mathematics by Inquiry program.
