Animated perimeter and area

For a recent session with teachers about whole school numeracy, I created a couple of animations demonstrating:

Woo2be: Videos for Teachers

Wednesday, 01 April 2015 ·

Eddie Woo (YouTube: misterwootube), creator of over 1500 videos for students of Mathematics (with 7000+ subscribers and over 700 000 views!) has launched a second channel for teachers of Mathematics. Looks like he will be featuring videos from conferences, teaching and learning ideas, useful resources, book reviews and more.

Great idea! Looking forward to watching.

End of Term 9 - world’s best paper airplane

Thursday, 20 November 2014 ·

I think I just found the activity for the last period on the last day of the year.

Video of myself in lessons

Sunday, 16 November 2014 ·

Looking at the area of special quadrilaterals, I wanted the class to make the quadrilaterals starting with paper rectangles.

This particularly class, however, struggle with step-by-step instructions. A document camera would be great, but I don't have one.

So I made a set of videos, these had the benefit of being large, on the big screen and something a little different.

Preparing to Engage, Enhance and Extend

Tuesday, 26 August 2014 ·

I am presenting twice in September about how I use technology to engage, enhance and extend in my teaching.

Simple Harmonic Motion with Sam

Sunday, 06 July 2014 ·

Back in 2012 when I first taught Extension 1 Mathematics, in particular Applications of Calculus to the Physical World - Simple Harmonic Motion (SHM), I captured this clip of my then 2 year old son:

Kitchen Scale

Monday, 28 January 2013 ·

I put up my first image on Dan Meyer’s 101 Questions yesterday, Kitchen Scale. Wander over there.

What’s the first question that comes to your mind?

Locker Problem

Monday, 06 February 2012 ·

I recently used the “Locker Problem” in a Year 7 Maths Enrichment class (mixed ability). Here are some resources I used:

Car Racing

Sunday, 11 September 2011 ·

Playing with the kids’ toys on the weekend, I came across this car and became interested by the relationship between pulling it back and how far it would travel.

Was it a linear relationship or something else?

Letters and Numbers

Friday, 10 September 2010 ·

Jeff of Webmaths points out a new Australian TV show, Letters and Numbers.

Term 3 2010 SDD

Monday, 19 July 2010 ·

Each year for the Term 3 SDD (Staff Development Day), the four schools (three 7-10 and one 11-12) in the collegiate I work in get together for a combined program.

Dan Meyer: Math class needs a makeover

Friday, 14 May 2010 ·

I think this is essential viewing for Mathematics teachers. I’ve been waiting for a meeting with my faculty to show them, which I got to do on Thursday.

Dan Meyer blogs at dy/dan, which you are already reading as a maths teacher… right?

End of term activities 6

Saturday, 05 December 2009 ·

The end of term/year often brings lots of disruptions. So, as much as I like to keep teaching till the end, some days require something a little different. I like hands-on quasi-mathematical activities that allow every student to engage with and complete. And on Thursday, just before having one of those disrupted days, I found this…

Introducing Probability

Sunday, 15 November 2009 ·

This is an amusing video to introduce probability… some of my Year 8s found it hilarious.

Teaching equations

Wednesday, 16 September 2009 ·

Year 8 were recently assessed on solving equations and I was a little perplexed by the results.

Surface Area and Chocolate

Sunday, 16 August 2009 ·

An excuse to use chocolate in a maths lesson…

Google SketchUp

Thursday, 02 July 2009 ·

Google Sketchup is one of the applications bundled on the DER netbooks being rolled out into NSW Public High Schools in Term 3. But as it’s free, you can download it now for Windows XP/Vista & Mac OS X.

The Perfect Tree

Tuesday, 12 May 2009 ·

I was preparing for part of a presentation to the staff at my school tomorrow, highlighting the importance of numeracy being included in all subject areas.

A story for Trigonometry

Monday, 02 March 2009 ·

A really easy way to create engagement when introducing a new topic is to explain some of it’s applications outside of the maths classroom. For Trigonometry, I use an explanation of how I used trigonometry in a previous career to find the height of trees.

Siftables, the toy blocks that think

Sunday, 15 February 2009 ·

This blog is about Maths teaching, however this year (as noted in an earlier post), I’m also teaching a computing subject: Information and Software Technology. Occassionally, I’ll post something that is more related to a computing subject than Maths, but hopefully everyone reading this blog will still find it interesting.

You Can Do Maths

Friday, 30 January 2009 ·

The Australian Association of Mathematics Teachers (AAMT) recently created a web-site called “You Can Do Maths”.  From the site:

The youcandomaths campaign encourages all young people and their families to appreciate the important role mathematics plays in many careers and everyday life.


Borrowing Money in Plain English

Thursday, 22 January 2009 ·

Another good video from The Common Craft Show.  This one is on Borrowing Money.

Saving Money in Plain English

Wednesday, 07 January 2009 ·

This video from The Common Craft Show is an excellent “introduction to the magic of compound interest and how it helps money grow over time”.  Keep an eye out for more videos in their financial basics series.

The Story of 1

Thursday, 01 January 2009 ·

Here’s a video about the history of number, in particular the numbers 0 and 1.  Our Year 7 program begins the year looking at ancient number systems, so this video will fit in nicely.
