Smart Ideas for Math

I've been reading blogs and message boards and email list archives and there are some smart people out there with good ideas for teaching math! I'm collecting some of them here/.

• I have saved a page in sore need of correction for a week later...did some teaching in the meantime...and handed the page back to the child for an "Oh, I get it now!" (Forum post)
• Make a rod-shaped tube from a trimmed 3x5 card & play puzzle games. "This end is dark green. What color is the other end?" Or, "Both ends are pink, what color is in the middle?" (Sep. 2003)
• To teach division or fractions, cut some string into sections about 1 foot long and tie them into loops. Then put some kind of counter evenly into the loops. (List archive)
• A Goblin Gaitor math game for learning greater than/less than. (blog)
• A place-value game where they roll the dice and trade in for 10s and 100s as needed, stopping to write the numbers every 60 seconds. (List archive)

There are so many good ideas out there - and math is way more fun than I ever imagined it could be!
