Exponents and Roots in IB MYP Grade 4 Mathematics
In IB MYP Grade 4 Mathematics, Exponents and Roots, within Number gives advancing learners (ages 14–15) the chance to practise using index notation, applying laws of exponents and working with fractional and negative exponents.
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 exponents and roots builds the knowledge and skills those criteria reward.
What learners practise
- Using index notation
- Applying laws of exponents
- Working with fractional and negative exponents
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 exponents and roots activities as a starter, homework or retrieval practice, and mix free and premium resources to differentiate.
When you get a question wrong, redo it a day later without looking at the solution. If you can do it cold, the idea has stuck.
