Parallel Vectors

Download the resource here Probably the last resource I will do on vectors, because I’m not sure how much more value I have to add on this topic. I think a lot of it just comes down to practice. There’s only 4 slides here. A little exercise about identifying when vectors are parallel, which I… Read More »

Introduction to vector geometry

Download the PowerPoint here Ok, so I found a bit of time today and put this together. It’s very basic, but covers finding ‘routes’ using vector geometry. It also covers midpoints. There’s not enough practise here, but that was deliberate. I would set them key skill K652/K653 on Dr Frost Maths to reinforce this skill.… Read More »

Magnitude of a vector

Download the PowerPoint here There’s two nice tasks here, and some presentation that I’m proud of. For instance, I tried to build up the difficulty here pretty gradually. There’s also room for discussion on the magnitude of vertical and horizontal lines. Moving to the skill we really want I thought this was a clever way… Read More »

Column Vectors

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 »

Interest

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.

Finding a percentage change

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.

One number as a percentage of another

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 »

Percentage of amounts [calc]

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 »
