Cuisenaire rod introduction

invented by a Belgian primary school teacher, Georges Cuisenaire (1891 - 1976)

wooden ones are more aesthetically pleasing

uses promoted by Caleb Gattegno






 Cuisenaire company set up in 1954 to market these particular bricks has Caleb Gattegno's booklets available

the particular colour scheme was chosen by Georges Cuisenaire to indicate relationships









this is a reasonably conventional coding system (in English anyway)

students quickly become used to the letters








there are various interactive versions available; the interactive whiteboard companies have versions

the NRich Cuisenaire Environment has no adverts and goes full screen

it takes time to get the rods out and put them away but it is worth the effort
one box usually suffices for 4 students


it can get noisy....
I prefer students not to build upwards









thanks to Keith Hedger and David Kent (Sigma project)
