## 'Cuisenaire Environment' printed from http://nrich.maths.org/

This text is usually replaced by the Flash movie.

Click on 'Rods', to choose a Cuisenaire rod and then drag it onto
the squared background. More rods can be added in a similar way and
aligned as you wish. A rod can be rotated by $90^\circ$ by clicking
any key whilst dragging. The background squares can be altered (for
example increasing/decreasing their size) using the 'View'
menu.

You could use this environment for all sorts of purposes - perhaps
to explore addition and subtraction, factors and multiples or ideas
about fractions.

For more ideas, look at the

Notes section, or go to

this page where there is a collection of Cuisenaire problems.
