Here is a collection of Vids from the 70's, 80's and 90's...I got "involved" in 1990...
It's always interesting to see the what happened before. We have been higher than we are now and we have been lower...I plan to take it at leaste as high and as far as it has been in the past.
For those with really short attention spans or who are pressed for time here's 90 seconds:
Here we are going back in time:
Look how far we have come. Back in the day these vids were hard to make and expensive. Cameras and editing cost thousands. Now you can get a computer camera and other equipment all for less than $1000.00
Here is Jerry going over some simple problems using basic operations pieces that are no longer manufactured by anybody...one day we will revive them...the idea is not to spend so much time building the problem you lose sight of the concepts, getting out even 16 unites to build a square takes too long. These problems are whipped together quickly because he has the pieces handy and they are "stuck together"...meantime you can also draw them but make no mistake starting out in the concrete makes all the difference.
Also take a look at this promo vid from the 90's.
Find us on Face Book and be sure to go to the house of math for more on math, how to present it with manipulatives and make it fun.
