Get the PowerPoint here As promised, here is a proportion in context lesson. Starts with just naming the type of proportion. I love the ‘buy-one-get-one-free’ example I came up with. I tend to teach direct, then indirect, then finish with these in context problems. I encourage solving both through algebraic methods and using something like… Read More: Proportion in Context »
Download the lesson here. Just a load of interesting (ish) ratio problems to work though. I used bar modelling. I am increasingly into bar modelling for KS3, although I’m still not massively convinced when it comes to negatives. I call these ‘reverse’ ratio problems. I don’t know if that’s the correct terminology. I have been… Read More: Ratio problems »
Download the lesson here. Something I’ve wanted to get around to completing for a while. I love ratio and I’ve got into doing a little bit of bar modelling. There’s some LOVELY questions in the White Rose Barvember stuff. This lesson has an example problem pair and some mini-whiteboard work. When I taught this lesson,… Read More: Sharing in a ratio »
Like the old ten quick questions, but with three levels of difficulty. Level one (first three questions) : Prime divisor Level two (second three questions) : Compound divisor Level three (third three questions) : 1 : n Level four (last question) : Units Tempted to extend it to do 12 questions. That last question feels… Read More: New Resource : Simplifying ratio timed questions »
Wrote this powerpoint today. It’s like my ProjectALesson stuff but I’ve taken A LOT of explanation out. I’ve also got some stuff you need to print out. I’m not sure making them ‘pick up and go’ was that helpful. It takes a lot of inspiration from variationtheory.com. It’s my new favourite website. It’s ACE. I… Read More: New resource : Equivalent and Simplifying ratio lesson »
Download the word file here This one was hard. I spent ages rearranging questions and looking at what should be added. Specifically, I had a massive dilemma when it came to introducing fractions. I was trying to point out the ways in which simplifying fractions and simplifying ratio were similar, but I’m not sure that… Read More: Vary and twist: Simplifying ratio »
