Recipes, Scaling and Best Buys
An interactive lesson on screen. Your child works through worked examples, practises on their own, then tests themselves with questions that get harder as they go.
About this lesson
By the end of this lesson your child can take any recipe or shopping question, scale it up, scale it down, or compare two prices, and know instantly which method it needs. A recipe that serves 6 scaled for 14 people gives your child four possible routes. Pick the wrong one and a two-step question turns into a page of ugly decimals.
Topics covered:
- Scaling with a whole number multiplier, for example 4 people to 12 people
- The unitary method, going through one person when nothing divides cleanly
- The common factor method, stepping down to a shared number then back up
- The common multiple method, stepping up to a shared number then back down
- Full multi-ingredient recipes, where your child picks the method
- Maximising one ingredient, and working out which way to round
- Best buys, comparing price per 100g and amount per pound
Your child works through this lesson on any screen. They click to reveal each step of a worked example, try the practice questions on paper, then click to check their own answer.
How it's structured:
- Each unit opens with a worked example your child clicks through line by line, then 10 practice questions colour-coded easy, medium and hard
- 102 questions in total, each with a click-to-reveal answer and a reveal-all option
- A final 20-question mixed challenge pulling from all 7 units, so your child has to choose the method as well as do the maths
Six hands-on tools, not just questions. Before each method your child gets a recipe scaler locked to that method. They change the number of people, every ingredient rescales, and the amounts stay hidden until they have worked them out on paper. The best buy comparator does the same for shopping, filling in both routes side by side so your child watches price per 100g and amount per pound land on the same verdict.
Use this if:
- Your child is in Year 4 to Year 11 and freezes when a recipe question has awkward numbers
- You're preparing for the 11+, where recipe scaling and best buy questions come up most years
- Your child is doing GCSE Foundation and loses marks on proportion and value for money
- You want a resource your child can check their own work with, not one more thing on your to-do list

FAQs
How do I access the lesson?
You'll get an email with your lesson link as soon as payment goes through. Click it to open the lesson in any browser, no login and no app to install.
How does the marking work?
There's no typing answers into a box. Your child works it out on paper, then clicks to reveal the correct answer and checks their own work. Full working is shown too, not just the final answer, so mistakes are easy to spot.
Does it work on a phone or tablet?
It works best on a tablet or laptop, where there's more room to read the examples and questions. It'll open on a phone too, but the text and diagrams can feel quite small on a smaller screen.
Can I use the lesson more than once?
Yes. There's no limit on how many times you open the link, so it's there for revision right up to the exam.
