Yeah, yeah, yeah you wrote some stuff, let me in NOW.
Once you BUY a password, click enter and over 10 hours of video await you! These Sample Lessons show by example kids learning math with base ten blocks. The vids you find here are for the most part exclusive to this page at The House Of Math. Your search engine will not bring them back for you even if you know the name of the video.
Ten and a half Hours is a lot of time but it goes by quick. None of them are more than an hour long and some of them are only 15 or 20 minutes. All of them show actual (very) unrehearsed lessons with real live students using base ten blocks. You can learn right along with them or observe how to teach a lesson yourself.
Here are a bunch of FREE VIDEOS you might want to watch if you haven't already...especially this overview. I know people who took almost a year (or so they tell me) to get to the point where they were ready to buy a password. That's how much there is for free. Others want one within a week of discovering this site because they want to know about how to present specific lessons...
Here is a short over view of what's on the other side:
Here is a longer overview with a few seconds from a couple of the videos you will find on the Sample Lessons page: samples of the sample lessons. In one we go from learning addends to square roots...in another a little girl is happily simplifying polynomial fractions! Manipulatives make it EZ!.
