Add-a-Square Blocks

3 Jul


To all my friends, collectors and lovers of esoteric educational equipment…

Have you ever seen these add-a-square blocks?  I received two boxes of them recently that were being discarded from a local elementary school.  I can see quite easily how to use them in similar ways to Math-U-See blocks or Cuisenaire rods, but they are different enough to be interesting to me.

I would love to know the history of these blocks (there’s no company or address listed on the boxes) and whether anyone every published any books or pamphlets of educational activities designed to be done with these blocks.  The general answerer of odd questions, Google, has so far turned up empty (“add-a-square” is too general a name and comes up too often, even when searched together with other terms).

They’re delightful little hardwood squares with non-toxic paint (so says the side of the box) and we find them fascinating.  So please, if you’ve seen them, or have other leads I could use to track them down, let me know!
