Mathematical Investigations

Mathematical Investigations in IB MYP Grade 4 Mathematics

In IB MYP Grade 4 Mathematics, Mathematical Investigations gives advancing learners (ages 14–15) the chance to practise testing a mathematical conjecture, justifying a mathematical generalisation and conducting an open-ended mathematical investigation.

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 mathematical investigations builds the knowledge and skills those criteria reward.

What learners practise

Testing a mathematical conjecture
Justifying a mathematical generalisation
Conducting an open-ended mathematical investigation

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 mathematical investigations activities as a starter, homework or retrieval practice, and mix free and premium resources to differentiate.

Study tip

Little and often beats cramming: ten focused questions a day will build more fluency than one long session at the weekend.

Quick answers

Who is the Mathematical Investigations page for?

It is for IB MYP Grade 4 Mathematics learners, typically aged 14–15, and for the parents and teachers who support them.

Are mathematical investigations 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.
