Rods! Or more specifically, CuisenaireÂ® Rods! Staples of my childhood arithmetic education: coloured wooden rods (now plastic, which will save them from the mouldy fate that befell some sets at Mearns Primary School), 1 Ã— 1 Ã— 1â€“10 centimetres long. Use them for counting, number lines, don’t-do-that renditions of Sun Arise, but absolutely never for flinging at tiny classmates.
Since it may actually have been Mrs. Cuisenaire who came up with the concept of rods, I drew a log cabin quilt section in virtual rods. The Gattegno in the title refers to Caleb Gattegno, the mid-century educator who popularized Cuisenaire’s work.
Should you too feel the need to have a virtual set of rods, here are some files you can play with in Inkscape (or any other SVG-aware editor):
The colours might be a bit off reality, but they’re near enough. I found it helpful to set a grid snap in Inkscape to 1 cm so that you could get the rods to align easily. If you want to get really nerdy, here’s the PostScript source I used to create the rods: rods.ps. I think I finally got the hang of basic arrays in PostScript â€¦
Creating this was in no way a means of me displacing getting round to doing my taxes this year, nosirree.
