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: Proportion in Context »
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: Inverse Proportion »
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: Direct Proportion (and being a Gem) »
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: Factorising Non-monic Quadratics »
Download the resource here Starts with a little task on finding the midpoint. I often find this trips students up more than you would think. Moves onto some example problem pairs and then a very (overly?) structured worksheet. I don’t know how I feel about this level of scaffold. At least it reduces. Then some… Read More: Estimating the mean from a grouped frequency table »
Download : Rearranging equations [No factorisation] Download : Rearranging equations [With factorisation] I never know what to call this topic. I’ve broken it down into two PowerPoints and I have run it for my year 9s over 3/4 lessons. The first PowerPoint is the better one. There’s a focus on what it means for something… Read More: Rearranging equations / Changing the subject »
I’ve been busy touching up some resources when I teach with them, and adding them to TES. Significant Figures : I updated this resource with a much greater emphasis on counting the significant figures before doing any rounding. I did this after having a bit of nightmare with my year 7 class teaching rounding. If… Read More: Updated resource and some misconception chat : Significant Figures »
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: Rationalising the denominator »
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: Surds and brackets »
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.
