For the new year

Here are some resources for the new year…

Mathematician’s Dice

Tuesday, 25 January 2011 ·

Feeling nerdy? Backing this project on KickStarter will get you a Mathematician’s Dice for just $5 (2 for $10, 4 for $20).

Rather than the boring numbers 1 to 6, these dice have the six most important numbers in mathematics on them — i, 0, 1, φ, e and π!


To a new teacher…

A quote:

Learning math is like learning to play the piano. First menial arithmetic and endless scales, but then Chopin and one’s imagination. @mathematicsprof

Having done both (learn maths and learn the piano) I love this quote. I hated scales when learning the piano. It wasn’t till I had got through my many years of formal piano lessons that I understood how fundamental learning scales was to everything I can do on the piano. As teachers of maths, we face that same kid, trying to convince them that what they are learning now will bring them greater understanding later.

Double Strength Cordial and Ratio

Monday, 17 January 2011 ·

When introducing the topic of ‘ratio’, I use the mixing of cordial as an illustration that most kids get.
The idea of using 1 part of cordial to 4 parts of water makes sense to them – and they get the idea of equivalence when you mix the cordial in a different sized container (I use the examples of using cups to fill a bottle for a picnic, and using buckets to mix a big batch for a party).

Coffee and Teaching Aids

Friday, 14 January 2011 ·

I wrote about my t-shirt box back in 2009.  It’s a resource I still use in my classroom.  When teaching surface area I have peel off sides for the box which can be placed on the board to show the net.
