“Oh, I get it!”

The ah ha moment when a 7 year old realizes she’s got a square quadratic and that she can put three x’s on the side and three more on the top and easily fill in the corner with 9. Thus the loudly spoken, “Oh, I get it!”. She then quickly figured out that it was easier to use three 3’s instead of 9 units to fill in the corner. While she was figuring all this out I sat back mouth closed hands on my lap because as she and I both agreed sometimes adults are just “a pain in the butt” because they try to do too much for the child rather than letting the child problem solve on their own. It took her some time to finish this, especially since she decided the dog and crocodile needed to have a little battle in between, but this was all her. The most awesome moment for me as a teacher was when she went to factor it and knew intuitively that she did not need to write both factors out but rather went right to using economy of symbol.

  1. I made a bunch of different flashcards for myself and the kids so they or I can just randomly pick a card from the pile to work on. I’ll post a pic of some of the quadratic cards on FB for you to see. I colour coded them just like the place value cards. Here’s a link to the Montessori place value cards. Keep in mind Mortensen Math came about because of the Montessori Method so thus the similarities in colours.

    1. Good link! Thanks. This morning I added a couple links back to your site and one more for a youtube video – maybe more but that’s off the top of my head. It’s slow but it’s coming. Expect to see more links to your site, blog, and videos. And thanks I’m working hard at it but it’s not easy or fast LOL.
