## Division of algebraic fractions

Download the PowerPoint here. I know this is usually covered in multiplying as one lesson, but I think there’s room to slow down. Example problem pair A card sort! (kinda). The idea here is that you don’t need to cut the cards out, just project them and ask the kids to copy them down in… Read More »

## Rearranging formulas and equations

Download the PowerPoint here. This is a big one! It’s at a minimum 3 lessons, probably 4. Starts numerically Next is something I have added after listening to the Mr Barton podcast with Naveen Rizvi. I realised I didn’t spend enough time talking about what the subject means! Some example problem pairs come next, and… Read More »

## Multiplying algebraic fractions

Download the PowerPoint here Last lesson for a bit. It’s half term next week and my wife will kill me if I plan resources on holiday. Decided to just to multiplying as one lesson. Don’t know if that’s too slow, but I think it’s worth practicing the skill. I quite like my second activity here.… Read More »

## Compound shapes with circles

Download the PowerPoint here. Went with an 80s look for the opening picture. I’m quite proud of these pictures I drew in GeoGebra. Feel like I’m getting the hang of drawing these. Moved some stuff around from the perimeters of sectors PowerPoint into this one. Includes a prior learning check thing. That’s an entire new… Read More »

## Simplifying algebraic fractions

Lesson PowerPoint here. Really tried to think through this topic and really break it down. As I have been doing, I added some whiteboard work, too. Quite like this small activity I’ve put in there. I like little things like this. Breaks things up a little bit. Missed the fact that one of my resources… Read More »

## Areas of triangles

Lesson PowerPoint here. This is a little different from regular lessons. There’s a worksheet (here) to go with it. I usually try and keep everything in one file, but here it just didn’t quite work. I’ve added pictures of the worksheet to the PowerPoint to make the questions easier to go through. I really think… Read More »

## Areas of sectors

Powerpoint is here I have circles and compound shapes to go and then that’s circles done. I made some pretty big changes to my area of a circle PowerPoint after doing some questions. There’s now a bit about choosing either the area or circumference formula, as this is an aspect students found really difficult. I’ve… Read More »

## Perimeters of arcs and sectors

PowerPoint here. I’m kinda on a roll. Not sure how I feel about this one, though. Maybe too close to the last two that I’ve done (in activity terms). Could do with a little more interest in there. I’ve also made some lovely sectors questions (first pic above) but I’m not sure exactly how they… Read More »

## Areas of circles

Lesson PowerPoint here. I decided not to go into parts of circles like quarters and halves, but concentrate on using the formula. I figured parts of a circle are easy enough to cover whilst teaching sectors. YMMV.
