Math: Applications & Interpretation · Mathematics Exploration (IA)
IB Mathematics Applications and Interpretation IA Grader
Upload your Mathematics Exploration (IA) and get criterion-by-criterion feedback against the IB assessment criteria in the official IB Mathematics Exploration rubric (first assessment 2021). Whether you are at Higher Level (HL) and Standard Level (SL), iBacalao shows where your draft meets the mark scheme and what to improve before formative submission. Free to start in the Mac app; sign-in is required to keep reviews and usage limits tied to your account.
IB assessment criteria — 20 marks total
Your Mathematics Exploration (IA) is graded against 5 criteria in the official mark scheme. iBacalao scores each one and tells you exactly where to gain marks.
Presentation
The exploration is coherent, well organized, concise and complete. A coherent exploration is logically developed, easy to follow and links to its aim. A concise exploration does not include irrelevant material.
Mathematical Communication
Relevant, appropriate and consistent mathematical communication: correct notation, symbols and terminology; key terms defined; appropriate use of multiple forms of representation (formulae, diagrams, tables, charts, graphs, models).
Personal Engagement
Evidence of the student engaging with the exploration and making it their own: thinking independently or creatively, presenting ideas in their own way, exploring the topic from a personal perspective, asking and addressing their own questions.
Reflection
Critical reflection on the mathematics and the process: reviewing, analysing and evaluating; considering the significance of results; discussing limitations and/or extensions; linking reflections back to the aim of the exploration.
Use of Mathematics
Relevant mathematics commensurate with the level of the SL course, explored correctly, demonstrating thorough knowledge and understanding. Mathematics below the level of the course caps this criterion at 2 marks.
Common mistakes to avoid
The most frequent reasons students drop marks on each criterion.
Presentation
- Exploration rambles or includes irrelevant material
- No clear introduction, body and conclusion
- Aim not stated or not linked to the work
- Steps left unexplained or hard to follow
Mathematical Communication
- Inconsistent or incorrect notation and symbols
- Key terms or variables left undefined
- Over-reliance on a single form of representation
- Calculator or command notation instead of proper math
Personal Engagement
- Topic feels generic or copied from a textbook
- No independent or creative thinking shown
- Ideas not presented in the student's own way
- Confusing effort or enthusiasm with engagement
Reflection
- Reflection is superficial or just descriptive
- No discussion of limitations or extensions
- Results stated but their significance not considered
- Reflection not linked back to the aim
Use of Mathematics
- Mathematics stays below the level of the course (caps at 2 marks)
- Errors in the mathematics or steps left unjustified
- Mostly prior-learning math rather than course-level
- Results stated without demonstrating understanding
Common questions
How is the IB Math: Applications & Interpretation Mathematics Exploration (IA) marked?
Your Mathematics Exploration (IA) is marked against 5 criteria totalling 20 marks using the official IB Mathematics Exploration rubric (first assessment 2021): Presentation (/4), Mathematical Communication (/4), Personal Engagement (/3), Reflection (/3), Use of Mathematics (/6). Each criterion has its own mark bands, and your teacher's marks are moderated by the IBO.
What are the most common mistakes in the IB Math: Applications & Interpretation Mathematics Exploration (IA)?
The two criteria worth the most marks are where students lose the most. On Use of Mathematics: Mathematics stays below the level of the course (caps at 2 marks); Errors in the mathematics or steps left unjustified. On Presentation: Exploration rambles or includes irrelevant material; No clear introduction, body and conclusion. The full list for every criterion is above.
Which criterion is worth the most marks in the IB Math: Applications & Interpretation Mathematics Exploration (IA)?
The highest-weighted criterion is "Use of Mathematics" and is worth 6 marks. The top mark band for this criterion is the most detailed, so missing any element it mentions is the fastest way to lose marks.
What is the word limit for the Math: Applications & Interpretation Mathematics Exploration (IA)?
Word and page limits for the Mathematics Exploration (IA) are set in the official IB Mathematics Exploration rubric (first assessment 2021) rather than being the same across subjects, so check your subject guide for the exact figure. Going over the limit risks examiners stopping at the limit and not marking what follows.
Can I use AI to help with my Math: Applications & Interpretation IA?
The IBO allows AI for research support and feedback, but the submitted work must be entirely your own. iBacalao gives criterion-by-criterion feedback on your draft — the same kind of comment your teacher would give — without generating any text for your IA.
