Ratio and Proportion in IB MYP Grade 5 Mathematics
Ratio and Proportion is part of IB MYP Grade 5 Mathematics, within Number. At this advanced stage (ages 15–16), learners work on solving inverse proportion problems and applying ratio and proportion to complex modelling.
MYP Mathematics is assessed against four criteria (A: knowing and understanding, B: investigating patterns, C: communicating and D: applying mathematics in real-world contexts). Regular practice with ratio and proportion builds the knowledge and skills those criteria reward.
What learners practise
- Solving inverse proportion problems
- Applying ratio and proportion to complex modelling
For students
Work through the worksheets, practice questions and revision resources at your own pace. Check your answers, then redo anything that felt tricky and explain each answer in your own words.
For revision
Use these resources for homework, end-of-unit revision and catching up on anything missed in class.
For teachers
Use ratio and proportion activities as a starter, homework or retrieval practice, and mix free and premium resources to differentiate.
Show every step of your working, then check each answer by estimating first. Examiners reward clear reasoning as much as correct answers.
Quick answers
Who is the Ratio and Proportion page for?
It is for IB MYP Grade 5 Mathematics learners, typically aged 15–16, and for the parents and teachers who support them.
Are ratio and proportion resources free?
Many are. Each resource shows a clear Free or price label, so you can start with the free ones and add premium resources when you need more practice.
How should I use these resources?
Pick one resource, complete it without help first, then check and correct. Repeating this little and often is more effective than one long session.
