In this period where I'm not in the classroom, I'm trying to keep myself busy with a few little projects. One of those things is working on updating my coding skills by creating interactive activities using Javascript. The first of these is a simple puzzle where the aim is to…

There was sport on today, so a large portion of my Year 7s were away. As a result, I had an exchange with some of the remaining students at lunch time that went a little like this: Student 1: We've only got 6 students in our class today! [Stretching the…

The other day I wrote a post about having students build their own equations. I decided to use this idea as a starting point for solving equations by backtracking. The class has already solved equations in a number of ways, and even used flow charts to solve them with backtracking.…

Year 7 are currently working on solving equations with pronumerals for the first time. Specifically, we're using backtracking to solve multi-step linear equations. This year, I realised there's a problem with getting students to understand backtracking. Before I can expect students to work backwards through steps to solve an equation,…

Semester 2 has started, which means the Computer Science elective I was teaching has ended. The good news is, I've taken over Year 10 Maths, which means my teaching load is more maths than it's ever been before. I haven't taught Year 10 for a couple of years now, and…

Teaching the distributive law is an interesting prospect. Because really, if students know how to multiply numbers with more than one digit they already use the distributive law, even if they don't know it. But if you write this on a board: a•(b + c) = a•b + a&…

While my Year 9 class is starting to move on to Area and Volume, I'm still quizzing them on Expanding and Factorising. At the start of Monday's lesson, I planned to hand out a short set of factorising practice questions to warm up with. At least, that was the intention.…

Only a week left of school holidays. I'd better get started on the huge list of things I mean to do over the break! I spent some time at school today working on an idea I had last week. My next topic with year nine (once we properly finish off…
