## Common Denominator

I already wrote about dividing fractions here and here. I use the explanation of “dividing by one” to explain why 5/6 divided by 2/3 is the same as 5/6 times 3/2. But when I was asked recently about how the “common denominator” strategy worked, my muted response was, “Because it does.” I didn’t mean to […]

## Math Worksheets

I often create worksheets for my students, even though every district-adopted math curriculum we’ve had has worksheets for students. I do this for two reasons: I teach differently — sometimes slightly, sometimes quite a bit — than what the curriculum writing team was thinking.

## dudamath.com

Ethan Hall, teacher and web entrepreneur from Israel, emailed me this morning asking me to check out his visual patterns generator on dudamath.com. There’s a lot of cool graphing tools other than the VP generator. I’m kinda blown away. Go play! Go do math!
