Download the PowerPoint here (thanks to MrBriggs on Twitter for pointing out that I forgot to add this link in!) This lesson went well, actually. Work out the gradients and try and notice something. Then there’s a little bit on making sure we can properly identify when something is a negative reciprocal. Obviously, an example… Read More: Equations of perpendicular lines »
Download the PowerPoint here. I quite like this one. It starts with a little whole class activity saying if two lines are parallel or not. If you click ‘check’ it’ll show you the graph. Nice! Then students have to do some solo work on this, matching up equations with the same gradient. This is a… Read More: Equations of parallel lines »
Download the PowerPoint here. Just an update, really. Someone contacted me about my HCF and LCM lessons being linked wrongly on here, and I realised that they were a bit crap, so I tidied them up. I removed a lot of ‘narration’ (I initially put these in to help teachers who just wanted to pick… Read More: Highest Common Factor / Lowest Common Multiple »
Download the PowerPoint here. This is my first post of the term. I guess I’ve started a week late. The reason is quite simple, I think I’ve got a bit of resource writer’s block! This PowerPoint is fine. It’s got an example problem pair. A discussion (which I’ve found a useful bit in my lessons.… Read More: Fractional Indices »
Download the PowerPoint here. OK. So this is a big one. Firstly, I have found teaching negatives difficult in the past. Teaching the rules is a bit useless. ‘Two negatives make a positive’ often leads students to doing things like -5 – 9 = 4 (or similar). I avoid the rules like the plague. I… Read More: Adding and subtracting directed numbers »
Download the PowerPoint here Bearings is a topic that I’ve taught really badly in the past. It’s due to a number of factors (teaching measuring, use of worksheets) but mainly I think due to a lack of thinking on my part about the different processes and skills contained within bearings work. I often lumped all… Read More: Calculating bearings »
Download the file here Based on reading Viable Maths by Peter Mattock. When I do equivalent fractions but I rarely do it with the aid of a diagram or a frame like I have here. I haven’t extended this to algebra, but I imagine it would not be difficult to do so.
Get PowerPoint here Completing index law week here. I added some whiteboard questions/rapid fire questions as I felt I didn’t have enough build up. As in the last few PowerPoints I spent time thinking about the questions I ask and the skills required. An SSDD type question. I need to add more of these to… Read More: Index Laws : Division »
Get the lesson PowerPoint here. Going with Jo Morgan’s suggestion of doing the power law after multiplying rather than after dividing. I wrote some challenging questions. There’s also a hinge question and some timed questions. I also moved on to changing bases. Because it’s really easy and a lovely way to introduce the idea of… Read More: Indices : Power Law »
Get the PowerPoint here Again, a lot of stuff is stolen from Jo Morgan’s great work. I mean, I’m never going to make something as beautiful as this. I wrote some questions. I think they’re quite nice. And I put some discussion slides in again
