Have you ever seen a math puzzle or game and wondered how it worked? Many of these math puzzles and game rely on the mathematical study of shapes and spaces called topology.
This unit gives students the chance to investigate topology through many fun hands-on activities!
We gratefully acknowledge the contributions by Stella Tam that enriched this resource.
LIST OF ACTIVITIES:
Topology is the mathematical study of shapes and spaces. It involves looking at the shapes that result through stretching, transforming, deforming, folding and twisting. Tearing, on the other hand, is not allowed!
Some of the shapes involved include polygons and circles which can be manipulated in space to create different shapes. These puzzles are a great way for students to explore 2-dimensional shapes in 3-dimensional space.
Topology: the mathematical study of shapes and spaces.
Flexagon: Folded paper polygons that have the fascinating property of changing their faces when they are flexed. Flexagons can be made from a pattern of squares or equilateral triangles.
Mobius strip/band: A strip of paper which has been given a half twist, and connected end-to-end. It only has one side and one edge.
Tetra-tetra-flexagon: A flexagon made from a folded paper rectangle that is 4 squares long and 3 squares wide.
