Math IA Examples: Teacher Feedback Guide for Mathematical Exploration

When reviewing a Math IA, start by checking whether the exploration is actually mathematical. A strong draft should make the problem clear, justify its methods, show purposeful working, and explain what the results mean. In IB Mathematics, the internal assessment is better understood as a mathematical exploration or mathematical inquiry process, so the first-pass feedback usually starts there. Used well, Math IA examples help identify the next revision priority faster.

Using Math IA examples: what to review first

On a first read, strong Math IA examples usually show:

• a specific mathematical problem or investigative focus
• assumptions that are visible and worth examining
• selected techniques or tools that fit the inquiry
• clear mathematical form and selective computation
• interpretation of results in mathematical or contextual terms
• reflection on what the mathematics can and cannot show

Teachers should still check the current IB Mathematics subject guide and school procedures for the relevant examination session before finalizing marks or feedback.

Review checklist for Math IA examples

Review area	What the teacher checks	Weak signal	Feedback move
Problem specification	The exploration defines a workable mathematical problem.	The topic is broad or descriptive.	Narrow the problem and state what the mathematics is meant to establish.
Assumptions	Assumptions are visible and connected to the model.	They are hidden or unexplained.	Explain how each assumption affects the model, result, or scope.
Selected techniques or tools	Methods, representations, or technology fit the problem.	Techniques appear without justification.	Explain why this method or tool is the right choice here.
Mathematical form	Notation, graphs, and formulae are accurate and readable.	Steps are hard to follow.	Clean up the mathematical communication so the reasoning is traceable.
Computation	Working is relevant and selective.	Calculation accumulates without purpose.	Keep only the computation that advances the exploration and explain what it shows.
Interpretation	Results are interpreted mathematically and, where relevant, in context.	The draft stops at answers or outputs.	Explain what the result means and how it changes the original problem.
Reflection and evaluation	The draft evaluates limits, alternatives, or model strength.	Reflection is generic or about effort only.	Explain what the mathematics can show, what it cannot show, and what could improve.

A feedback workflow for Math IA examples

1. Confirm the task as mathematical exploration.
2. Check the problem and assumptions first.
3. Review method choice before sentence-level wording.
4. Separate computation from interpretation.
5. Write two or three revision priorities.

Common issues in Math IA examples

• The topic is broad. It still needs a specific mathematical problem.
• Methods are used without justification. Techniques should be chosen for a reason.
• Computation overwhelms inquiry. Working needs purpose, not bulk.
• Results are shown but not interpreted. The mathematics needs meaning after the answer.
• Reflection is personal but not mathematical. Evaluation should address the mathematics used.

Reusable comments from Math IA examples

• "Clarify the exact mathematical problem so the reader can see what this exploration is trying to establish."
• "State the assumption clearly, then explain how it affects the model or the scope of the result."
• "Explain why this mathematical method is appropriate for the problem you are investigating."
• "Keep the working that advances the inquiry, and cut calculation that does not change the mathematical argument."
• "After the calculation or graph, explain what the result means mathematically."

Weak vs stronger feedback

Weak feedback	Stronger teacher feedback	Why it works
"Need more maths."	"The exploration introduces relevant mathematics, but it still needs to show why these techniques are the right tools for this specific problem."	It turns a vague comment into a judgment about method choice.
"Explain your graph."	"After this graph, explain what pattern matters mathematically and how it helps answer the original problem."	It moves the draft from display to interpretation.

Safe AI use

AI can help draft Math IA feedback, but teachers must review mathematical accuracy, interpretation, and final wording. Teachers decide the final judgment, and AI should not be presented as giving official IB marks or replacing teacher assessment. Teachers should check the current IB Mathematics subject guide and school procedures before finalizing feedback or marks.
