I am spending the summer in a major overhaul on the house, attic and basement. I am finding any lost pieces and re-filing all my paperwork…why? Not because I am a glutton for punishment, but because I need to get my head and heart ready for the new school year game.
I came across this list of sizes for the trinomial and binomial cube…and thought I would share. I did this a few years ago and I am missing a few pieces so I need to find a good source of cm blocks in bulk again…anyone??…besides I want to make the painted and unpainted versions!
OK…measurements…the Trinomial is made up of 3 cubes and 7 sizes of prisms(but more than one of each size as follows:
Prisms of Trinomial:
All of the 4×4 faces are red.
All oif the 3×3 faces are blue.
All of the 2×2 faces are red.
All non-square faces are black.
Cubes of Binomial :
All 4×4 faces are red.
All 3×3 faces are blue.
All 3×4 faces are
When we made ours a few years ago, I used wood cm blocks and joined them together with wood glue. I just made the Trinomial Cube the first time as the cubes and prisms of the Binomial are the same…They aren’t 100% square, but we did not mind. (in truth, they looked pretty darn good IMHO 😉
We also did not paint ours…I was intending to make another set that I would paint (after coating it with a bit of wood filler)…the kids enjoyed seeing and feeling how many cm blocks made up each cube or prism. At the time, I did not even make up the cards for the cubes either…this time I am. I hope this helps someone!
