This session for Association of Teachers of Mathematics 2021 Annual Conference<\/a> will give you some ideas for using origami for teaching and learning mathematics.<\/p>\n

It\u00a0 covers fractions, volume, curves from straight folds and more. It is https:\/\/www.atm.org.uk\/write\/MediaUploads\/Conference\/2021%20Conference\/785_Day_2_Programme.pdf<\/a><\/p>\n

Two basic folds<\/b><\/p>\n

A valley fold is concave. A mountain fold is convex. Most origami diagrams used a dashed line for valleys. Mountain fold is usually dash-dot-dot.<\/p>\n

Fractions<\/b><\/p>\n

Folding in half, quarters, eighths, sixteenths, etc is easy(ish)<\/p>\n

How about dividing the edge of a square into thirds? See end of webpage https:\/\/www.foldworks.net\/home\/diagrams\/<\/a><\/u><\/span><\/span><\/p>\n

Dividing a square into thirds: Here are eight methods for dividing a square into thirds. How can you prove each method works? What are the advantages and disadvantages of each method? Which methods can be generalised to oblongs and other divisions e.g. fifths and sevenths?<\/figcaption><\/figure>\n
