'Cuisenaire Spirals' printed from http://nrich.maths.org/
Here are two open spirals made from cuisenaire rods.
I used only the even numbered rods.
Full Screen Version
You can experiment making spirals using the rods on this computer activity below.
There may be some sets of real Cuisenaire rods in your school.
This text is usually replaced by the Flash movie.
Click on 'Rods', to choose rods and and drag them onto the squared background.
A rod can be rotated by $90^\circ$ by clicking any key whilst dragging.
You can change the background squares (smaller or larger) using the 'View' menu.
When you've done a lot of exploring you might like to try the something similar with numbers.
If you do, have a look at Number Spirals here
