# Multiplicative reasoning: TES Maths Resource of the Week

To see all of the work I do for TES Maths, including Resource of the Week, Inspect the Spec, Pedagogy Place, Maths Newsletters and Topic Collections, please visit the TES Maths Blog here

What is it?
This is brilliant. It is a PowerPoint full of questions and worked examples that covers pretty much all of multiplicative reasoning at GCSE. And when I say pretty much all, I really do mean it. Here are the sections:

• Prior knowledge check
• Growth and decay
• Compound measures
• More compound measures
• Ratio and proportion
• Problem-solving
• Check up
• Strengthen
• Extend
• Knowledge check
• Unit test

Each one contains slides of really well thought-out questions for students to try, complete with hints, notes and worked examples. And if that wasn’t enough, there is also an accompanying PowerPoint complete with all the answers!

One review from a teacher who has used this resource sums it up better than I ever could: An immense PowerPoint that covers an amazing amount of topics. Very impressive, thanks for sharing.

Wow, indeed.

How can it be used?
This is essentially my in-class and out of class assessment needs for multiplicative reasoning taken care of. I will use some of the questions as practice for my students in class following worked examples and discussions. And I will use the rest in starters, mixed-topic homeworks and low-stakes quizzes across the course of the year.

I love the way there are questions designed to help students develop fluency, but then also really well written reasoning and problem solving questions too. This really is the complete package, and I know it will save my hours in my planning.

I just hope the author decides to do this for every other GCSE topic as well

Thank you for sharing!
