MATHSPLAIN - THE MATH IS PLAIN

june 2015 by simonjob

This website was created to demonstrate that learning math can be fun, if everything is kept simple and easy to understand. Try our new online training site where things are clear, nothing is boring, and it turns out that math is actually very simple. Try our new online training in Calculus, or Linear algebra, or Probability theory where things are clear, nothing is boring, and it turns out that math is actually very simple. The point of math is not WHAT you should do, but WHY you should, and that is exactly what you will discover here: not via muddled theory, but through simple, practical examples.

What I Notice and Wonder about Teaching Like a Champion | teaching/math/culture

april 2015 by simonjob

Last night, Chris Robinson shared an experience with an administrator who observed his math classroom. He had been doing an activity called Noticing and Wondering with his students, something that Max Ray of the Math Forum has written about extensively. Noticing and wondering is a great discussion starter. You share a mathematical object or situation with…

Day 130: Paper Folding | Quadrant Dan

april 2015 by simonjob

Algebra explored the expansion of (a + b)² today. Across 100 students, none of them were able to correctly expand (x + 3)² coming into the day. We plugged x = 2 into different expansions. Most students had 13, some had 25. Everyone agreed that 25 was spot on, but couldn't come up with an explanation as to…

Music Puzzles | Solve My Maths

iPad Use, Years Later — Infinite Sums

march 2015 by simonjob

I've had iPads in the classroom since the fall of 2012. It started with 4

and now I have a pile of 25. What world changing things are we doing these

days?

Honestly, no one would build an ad campaign around it. My primary workflow

is rather dull.

I've played around with exporting student work and sharing photos. It

served a purpose but at my current scale isn't practical. I tried

collecting data in spreadsheets and sharing it, too many kids had nothing

to do. I tried have them analyze a video. I tried having them model

equations to pictures. In each case the time investment ratio was just out

of whack. There were simpler ways to accomplish the same thing. Despite how

easy it was to gather stuff via Google Drive, I could never find other uses

for it. Despite how easy it was to have them try and teach themselves, it

was just glorified handouts. I like for them to keep records of everything

we do. I still love paper and pencil, marker and glue. Can we make that

better?
