Proportion in Context

Get the PowerPoint here As promised, here is a proportion in context lesson. Starts with just naming the type of proportion. I love the ‘buy-one-get-one-free’ example I came up with. I tend to teach direct, then indirect, then finish with these in context problems. I encourage solving both through algebraic methods and using something like… Read More »

Inverse Proportion

Download the PowerPoint here Very similar to my last lesson, but looking at indirect. This all ties together with a proportion problems PowerPoint which I will upload before the end of the week, where you have to pick if you’re using direct or indirect. I’ve also updated the ratio lessons I’ve done and added them… Read More »

Direct Proportion (and being a Gem)

Download the PowerPoint here A really simple PowerPoint covering direct proportion. I’ve deliberately left context out of it here and focused on questions that ask you to use the formula. There’s some example problem pairs and some exercises. Gotta say, I love a good fill in the blanks question. Makes you think forwards and back.… Read More »

Factorising Non-monic Quadratics

Download the PowerPoint here Trying to get back into the swing of things. I use grid method to do this. I’m a big proponent of grid. Reading through Jo Morgan’s amazing Compendium of Mathematical methods, there’s loads of approaches. But I like to use grid for everything. I’ve also updated my expanding double brackets and… Read More »

Rationalising the denominator

Download the worksheet here Thanks to @mathsiskind on Twitter for pointing out that I nearly uploaded this resource with ‘rationalising’ spelt wrong every time. NO!!!!!!!!! pic.twitter.com/DocTNrpXrT — be kind, shashi (@mathsiskind) September 24, 2021 I am really liking forwards/backwards activities at the moment. Fill in the gaps etc. They can be great for a bit… Read More »

Surds and brackets

Download it here Pretty simple stuff. But I’ve tried to add a bit of backwards/forwards thinking here. I might even do rationalising next week. (I’m teaching this topic at the moment but I don’t always upload the slides I teach as they’re not 100% complete a lot of the time). That will mean the surds… Read More »

Addition of surds

Download the lesson here There isn’t much here. I was just trying to explicitly teach something I often leave in passing. (ie that surd addition works like collecting any other like term). Not a full lesson. Just maybe an activity to throw in.
