We discovered thisin a previous exploration involving triangles of different types.Ģ) In GSP, draw a four sided figure. 1) The angles of a triangle forms 180 degrees. Where n = thenumber of sides of the polygon. This template starts from a square, but you can start from any regular polygon (a two-dimensional shape in which the edges are the same length and the angles are the same).The first lesson that I want to do involves the formula for finding thesum of the angles inside a polygon. Pursuit curves use straight lines to create beautiful logarithmic curves. Pursuit curves instructions and template.What other impossible shapes can you draw? If you don’t have a printer, just freehand it, or trace the template from your screen onto a piece of paper. An impossible triangle is a triangular shape that can be drawn on paper but can't be constructed in three dimensions.
Impossible triangle instructions and template.Once you have completed your drawing ask yourself what else you can draw - how about an impossible square, or pursuit curves starting from a triangle or hexagon? We have two drawing activities - an impossible triangle and pursuit curves - both of which are explained below. There are many fascinating mathematical shapes and objects that can be drawn. (Requires a printer, scissors, and tape or glue.) Mathematical colour cube, a selection of six different colouring activities that can be cut out and formed into a cube.We have instructions for drawing these below. Curves of pursuit, beautiful logarithmic spirals from straight lines.If you don’t have a printer, use graph paper or draw any size square grid and follow the same rules to colour it. Latin Square, like a Sudoku with colours.If you don’t have a printer, draw your own ‘map’ and follow the same rules to colour it. The Four Colour Theorem, a famous and once controversial result in mathematics.Once you have coloured in a sheet, don't stop there - ask yourself if there is any other way to colour the sheet and still solve the problem? In maths, there are often many solutions to a problem! We have four mathematical colouring sheets demonstrating different types of colouring problems. There are many interesting mathematical problems involving colouring. Instructions and videos for assembling Sonobe units into these and other polyhedra can easily be found online. The key to assembly is that each pyramid is comprised of three units, and the pyramids are arranged in groups of four around a central point. Assembling a small triakis octahedron.This requires six Sonobe units - two units in each of three colours works particularly well. Take your time to fold neatly and precisely as it will pay off when you assemble the units! A good size is between 10 x 10cm and 20 x 20cm.
Square pieces of paper, 6 pieces for a cube or 12 for an octahedron.(A triakis octahedron is an octahedron with identical triangular pyramids attached to each of its eight faces.)

These instructions show how to fold a Sonobe unit, then assemble 6 units into a cube or assemble 12 units into a small triakis octahedron. Each unit is folded from a single piece of paper. The origami we use is called modular origami, because polyhedra are made by joining together multiple simple modules or units. It is possible to build polyhedra using origami. What other ways can you join Möbius strips and cylinders, and what does it create?Ī polyhedron is a three-dimensional shape with flat faces, straight edges, and sharp corners.

The Maths Craft article featured in the latest issue of Connected is written especially for students in schools, and guides readers through exploring the Möbius strip. A great way to investigate Mobius strips is to cut them up! These handouts take you through creating and exploring the surprising wonders of the Möbius strip. A Möbius strip is a surprising object it’s a surface with only one edge and one side.
