Download the PowerPoint here Three example problem pairs, and three exercises covering the basics of vectors. Notation, adding and multiplying. There’s probably two lessons here. No real vector geometry, which I find so difficult to teach. I’m going to need to do a bit of research before I tackle that. I quite like these questions… Read More: Column Vectors »
Download the PowerPoint here Both simple and compound here. I couldn’t make simple a full lesson. I’d separate this into two lessons. Also some nice little one slide questions. Pupils should use trial and error.
Download the PowerPoint here Again, the language here. Finding a percentage change. It can easily be confused with changing by a percentage. I need to have a sit down and think about how I talk about the language here, and how specific I am. Especially with our EAL learners.
Get the PowerPoint here One thing that redoing some of my percentage PowerPoints has driven home is just how subtle the language around percentages is. We can have the percentage of an amount, the percentage change, changing by a percentage and one number as a percentage of another (among others). No wonder pupils get so… Read More: One number as a percentage of another »
Download the PowerPoint/Worksheet here Lots of stuff here. I use the ‘work out 10% first’ method. I stole the mind map idea from Don Steward, who came up with the best tasks. I’ve done another Blooket, too.
Download the PowerPoint/Worksheet here I’m going through and updating my percentages PowerPoints so that I have all of percentages done and ticked off. Here’s the percentage of amounts with a calculator one, I’ll upload percentage of amounts without a calculator next. I like to separate the two skills. I also make a blooket. You can… Read More: Percentage of amounts [calc] »
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 »
