TEDtalks and Maths

adam spencer ted

Sometimes when we’re needing a break, we take some time to indulge in the wonderful world of TEDtalks. More importantly, we love discovering TEDtalks that are all about mathematics. Here are a few talks that we think are worth a look at:

Adam Spencer: Why I fell in love with monster prime numbers

Hannah Fry: The mathematics of love

Scott Rickard: The beautiful math behind the ugliest music

Harry Baker: A love poem for lonely prime numbers

The Sounds of Pi

o-PI-NUMBER-facebookMarch 14th marks Pi Day! Each year around the world maths enthusiasts celebrate that symbolic Greek letter (“π”) that represents the circumference of a circle to its diameter.

Why is Pi Day March 14th you may ask? Well, that all comes down to the form of writing the month before the date (3/14 – March 14). Smart hey!

To celebrate the annual event, we have found a video posted by Michael Blake on YouTube a few years ago. This video presents what Pi would sound like if played on several musical instruments.

Enjoy and Happy Pi Day!

The best parts of HOTmaths, decided by you.

We recently ran a competition asking teachers to tell us what they liked about HOTmaths.  Congratulations to the winner, Warren Richards from Queensland.

Dozens of teachers told us about their favourite parts of HOTmaths, sharing expert advice and classroom experiences.  While a surprising number of features were nominated, there were three clear winners. Nearly 50% of teachers told us they loved the test generator, while 35% mentioned the widgets and 32% liked the printable HOTsheets.

So why do teachers love the test generator, widgets and worksheets?  Here’s what some of them had to say.

The Test Generator

The Test Generator library

The Test Generator library

“I recently tried using the online assessment and was surprised how easy it was to set up, wishing I had used it earlier.” – Elizabeth, Burradoo NSW

Don’t let 2014 slip by without trying the Test Generator!  This is by far the most popular part of the site, with nearly half of all respondents recommending it as an easy way to create online, automarked assessment activities tailored to your needs.

“I particularly love the breadth, depth and creativity of the test questions. Some of them are so clever in their design and really get my extension class thinking!  The less able students are catered for due to the ability to differentiate the level of question asked. To be able to then look at each student’s results per question is fantastic!” – Leah, Ringwood VIC


Trig functions widget

35% of respondents recommended the interactive widgets on HOTmaths.  Not only are they brilliant for in-class demonstration, they really make a difference for students who struggle with new ideas.

“I love being able to login in the classroom and show the students all the widgets, it’s often only then that the lights come on. Students can see demonstrated, in a fun way, what I have been trying to teach them all along.” – Charlene, Mayfield NSW

Need a widget for today’s class?  Just type the concept you are looking for into the search field, open the widgets tab and take your pick.


HOTsheet matching graphs and vessels

Nearly one third of teachers told us that the printable HOTsheets are one of the best parts of HOTmaths. With hundreds of them easily accessible through the online search feature, they are helping teachers set homework, cater to fast finishers and provide stimulating classroom activities.

“The HOTsheets are usually exactly what I’m looking for to introduce or consolidate students skills” – Chloe, McKinnon VIC

“One thing I really liked about HOTmaths is the simple to challenging worksheets. The best part is they come with their solutions.” – Manpreet, North Rocks NSW

If you haven’t yet tried out these popular tools, now is the time to give it a go!

You can access advice and instructions via the HOTmaths help, available through the question mark icon when you are logged in.  Or contact your Cambridge consultant for advice – we’re happy to help.

Problem solving with HOTmaths

Did you know that the HOT in HOTmaths stands for Higher Order Thinking?

Cambridge HOTmaths, Australia’s premier online maths resource, has been designed from the outset to help learners develop skills in problem solving, analysis, evaluation and higher order mathematical thinking. Here are some of the ways HOTmaths helps students develop as confident problem solvers.

FUNdamentals activity - Balloon Pop

FUNdamentals activity – Balloon Pop

For students in the first three years of school, the FUNdamentals page in HOTmaths offers a wealth of highly visual learning activities. Students solve problems by exploring, playing, and doing, with visual and spoken feedback provided along the way.

Teaching Notes - Addition and subtraction strategies

Teaching Notes – Addition and subtraction strategies



Teaching notes support this approach, suggesting creative ways to teach a variety of learning strategies, and providing flexible resources and interactives to help demonstrate them.





Walkthrough - Tree Diagram


For students in Years 3-10, HOTmaths offers a range of resources that help students learn to think and work like mathematicians. For example, walkthroughs offer challenging multi-step problems, with hints and advice provided at each point as students work towards solving the problem.







Worksheet - Algebra flowcharts

Worksheet – Algebra flowcharts


Printable worksheets offer investigations, puzzles, and problems, and often require students to apply their mathematical skills to the real world scenarios or combine knowledge from several different areas to find the right answer. Worksheet solutions are always available and offer additional information, notes on language, and different strategic approaches.






Challenge Questions - Circle Geometry


HOTmaths also offers hundreds of individually written Challenge questions that require students to use problem-solving skills to analyse the question and find a solution.

The best way to see some of these challenging problems is to try out HOTmaths with your class and see how they do. You can project walkthroughs or questions onto a whiteboard, print out worksheets or Challenge questions for small group work, or even assign different tasks to different students, to cater for different learning needs and abilities.
