Here is just the last 16 minutes if you already watched the vids on the blog.

I will be moving many vids with Dboyz doing amazing math here shortly...vids you won't find anywhere else...no matter how much you search youtube or the internet.

Be sure to check out the password protected screencasts too.

And here is their very own Blog: Math Genius Making!

This one doesn't have DBOYZ in it but it is a sample lesson you may find worthwhile.

OK now here they are doing it:

HOURS of vids for you; many of these are going to start disappearing from youtube because they are going to be "unlisted" and you will have to have the link to view them. Like this one:

Here are the boys playing subtraction. "Talk to the ten!"

Here is more algebra: This was a GREAT LESSON for me. He was looking at the 6 upside down and saw 9 so he answered 5 + 6 = 14 instead of 11 because we were looking at the SYMBOLS and what he saw was more important that what he heard...when he took a second to process what he was hearing as opposed to what he was seeing he got 11.

Important concepts to understand here. They stumble in exactly the same places high school and college kids do...but by the time they are teens these concepts will be second nature.

It got cut off at the end, but basically I was explaining that I give him a hard time because he's my son...but that I was very pleased with his work today. And then they did their usual Crewton Ramone's house of math sign off...but the camera died. Happily the lesson was over so we didn't really lose anything...less than 30 seconds got cut off.

Also we talked about it afterwards and the reason he said 14 when adding 6 + 5 is that he was looking at it upside down and the 6 does indeed look like a 9 when you are looking at it upside down so he automatically decoded the symbols as 9 + 5 and got 14 even though he heard 6 + 5..."I know what 6 + 5 is dad...I've been doing it my whole life!"

A note to those with dyslexic kids...what they "see" and the decoding going on there is usually more "powerful" than what they hear.
