  • Solving by factorising

    Download the lesson here

    This is a follow up to my factorising quadratics lesson. I taught this two weeks ago, but I was cleaning up the slides to be put online. I really think the exercise that goes along with it is nicely thinky. Some variation and slow build up of activity.

    3 leads on to these problem solve-y questions
    Not a huge lot here, but I thought this lesson and my other quadratics lesson here sequenced well.

    Other thoughts

    • I’ve been doing barvember. The pupils in my year 7 class have kinda hated it, which proves just how valuable and needed it was. These questions are so high quality, and it’s lovely to show how you can do some of these problems just with bars and basic four operations knowledge. I laminated some responses from the pupils, and they loved seeing their work up on the board. Great stuff.
    • This blog is going to break it’s usual format for the next few weeks. Next week I’ve got some starters for you, the week after … ChristMaths is going to be published early.

  • New lesson: Finding roots of quadratics by factorising

    This is my biggest set of lesson stuff yet.

    The PowerPoint introduces the topic. It sets up some example-problem pairs.

    It then leads onto some vary and twist questions, which are available here as Word file.

    The PowerPoint then goes onto talking about solving when rearranged and includes a Victorian textbook exercise and some questions where you have to find x, given the area of some shapes (this took ages to do. I posted it to Twitter twice. Both times the questions were written wrong. Doh!)

    I’ve also included an open middle problem solving thing and a timed learning check, that graduates in difficulty.

    Talking about learning checks…I’ve also written some Timed Questions that increase in complexity every 3 questions. I now have over 6000 questions in my Timed Questions database!

    As always, comment and critique.

    There’s probably 2 lessons of stuff here, easily.

    EDIT: One of the area problems was still wrong! Thanks to Professor Smudge for catching that 🙂
