  • 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 on TES was Mr Barton’s resource of the week! That’s nice.

    Noticed, though, that it’s not the up-to-date version that’s linked on this site.

    I am aware no one uses this site, and that it’s better to have stuff in one place, but it’s annoying having to update stuff on TES every time I improve a resource (it automatically does it here). I don’t think I’ve got the time to maintain an account on TES and here. But TES is where people see stuff.

    Mmmmmmmm.

  • 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 fit into the lesson. There’s a big lesson about using the formula and then some questions at the end where you don’t really need it. Hmmmm. They’re nice questions, though.

    Also I think I should have included more questions on half circles and quarter circles. Or shunted some into the circumference PowerPoint. Might have a think about that.

  • Circumference of circles

    Lesson powerpoint here.

    The questions here lack a little of the meta tasks I’ve built into other stuff. But I’ve tried to build as much thinking into this as possible.

    Here’s a little gallery of what you’re downloading.

    Areas of circles next, I think.

    I know some of these lessons are ‘prescriptive’. I don’t want people to get the wrong idea. In the lead up here I did a lesson on ‘discovering pi’. Using string to measure circumferences. The pupils found it really hard!

    Measuring a circle is difficult!

    We then used the ‘wisdom of the crowd’ and collated all our answers to get close to pi.

    We got 3.3 ish. Eeeek.

    I’m not sure if doing this helped students get a feel for pi. Measuring was so hard that students didn’t really feel like each circle they measured had the same ratio.

    But I’m still glad I did it. Sometimes it’s nice to do things like measuring and to let go of student’s hands and see how they cope. Hopefully they’ll also have an appreciation for why it’s better to use the formula than measure when we come to do this lesson on circumferences.

    PS : Gonna look through the links at the top and start cleaning up the sections. I’m sure there’s materials I’ve made that haven’t been listed up there.

    PPS : It’s worth occasionally redownloading the PowerPoints. I often tweek and change stuff as I teach. Everything is a work in progress. Give me 20 years.

    PPPS : Don Steward’s questions on this are, as always, brilliant.
