Cool Math

This morning we checked out the site Cool Math 4 Kids.  Georgia reviewed fractions, factors, and reducing fractions.  Olivia worked on addition, subtraction, number values, meaning of equal, and using a number line. We also used cookie cereal and some empty fruit cups for playing around with addition.

Doodling in Math Class

Found a really neat site from a recent NPR piece.

Ulam Spiral.... Pascal's Triangle.... graph theory.... Ouroboros.... Borromean Rings... Knot Theory... you still with me????

This site  is by Vi Hart, who puts fun back in math with her videos and tips and tricks.  Vi describes herself as "a recreational mathemusician" and as evident in her videos, loves math, music, being creative, and having fun with it all.  Georgia sat in front of the laptop for over an hour watching her videos with sketch book in hand.  She had a lot of fun trying the techniques shown in the videos...especially this one.

I'll put Georgia's sketches here when I get to the other computer.
