Here's a great activity for fractions (you could probably pick just about any fraction topic and connect it to this). Thanks to @normabgordon for creating it

My favourite thing about this video is that with a typical solution you might hear a phrase like "cross multiply" but here @Howie_Hua uses one of my favourite properties - so good.

I think you could easily connect this multiplication (and division) strategy to binary.

I have been a fan of the Mathies.ca math apps for years and was disappointed when they went away when Flash went away. But some money has been found and some of them have been recreated in HTML5 so that they will live on. Currently, the Money app and the Colour Tiles app have been released with others on the way (some of the other minor apps are also in HTML5).

We were just talking about this very thing at my school. The idea that math is more about choosing the most appropriate method, not just the standard algorithm.

Lots of stuff this week to support the newly released Grade 9 Math curriculum. Firstly a new (to me) resource BHNMath that has all sorts of resources for Ontario secondary school students, parents and teachers. For example, there are a lot of references to story telling in the new grade 9 curriculum and so here is a resource for topic ideas for those expectations. Thanks to @RobinMath3 for pointing this resource out.

I have mentioned GraspableMath before but it's come up in my feed from a few different places so I thought I would mention it again. If it's new to you then check it out, you'll love this dynamic algebra system. If you already know about it then you know what I'm talking about.
