We have the binomial and trinomial cubes. Sean has used them since he was in primary, and I distinctly remember him showing me both of them during an Open House when he attended the private school.
But now we are homeschooling for Upper El, and I really wanted to present them algebraically. I'm not Montessori trained, so I watch a lot of Margaret Homfray videos when I can. Before I found her presentation of the binomial cube for primary, which is amazing, I watched a few Youtube videos of others presenting the material. It was confusing, because no one did it the same way.
And while Homfray showed how to present it to the child in primary, and then explained it to the adults in algebraic terms, I didn't think the way she explained it to the adults was the way to present it to a child in Upper El.
So I kept looking. And I got more confused.
Then I just stopped. I gave up, and decided at some point down the road I would stumble upon someone who could help me, or a video that was the correct presentation.
Fast forward a few days, and I was looking for some Montessori cards for the parts of an Atom. I found some at Montessoriforeveryone.com, and while I was there I decided to look at some of their other pdfs to see if there was anything that I could use.
WHAAAAT? There they were. The binomial and trinomial cards, along with instructions.
I've used Montessoriforeveryone.com several times. The cards are affordable, and come as a pdf that you print on your own, and laminate if you choose.
I'm going to practice several times before I present the binomial cube, and I'll be observing to be sure that Sean is ready for the presentation.
No one at Montessoriforeveryone.com has asked me to write this post, nor has the company given me a discount, or anything for free.
