This was a short fun little lesson with two young boys...and part way through I remembered to take out a camera.
The younger boy did not want to participate in the screencast but then he watched the finished version and had to prove to me it wouldn't take him a week and a half to count all those three's. First he counted by threes as far as he could which was 18. Then he went back and started counting by ones and lost count at 24...and ended up with 28 instead of 27...and then the third time he got it right. (The next day we were in the car skip counting and he skip counted by 2's, 3's, 4's and 5's all the way to 12.)
Now as you can see algebra is not out of reach of the mind of a young child if you present it at their level. Here is basically a lesson on counting and skip counting and the algebra is just along for the ride...
You can also see the kid is being a brat, when I ask what's 2x plus one x and he says butt x...owee x...but he recants at the end of the vid.
Here is a video of an actual session about a week later:
Be sure to share links to these vids with people you know who ave base ten blocks, especially from Math U See and Mortensen Math. Also Homeschoolers should be able to see how easy putting algebra into beginning lessons is...
Look over the website and this blog and you can see algebra is an integral part of the method and it's easy and fun.
