If you are thinking, “My child doesn't understand IB Math, what can I do?”, begin by identifying the precise source of difficulty rather than responding only to a disappointing grade. IB Mathematics can expose gaps in prior knowledge, problem-solving, calculator use, mathematical communication, or exam technique, and each problem requires a different response.
Your role is not to reteach the course. It is to help your child explain what is going wrong, communicate with the teacher, establish a manageable practice routine, and obtain targeted IB Math AA or AI support when necessary.
Understand which IB Math course your child takes
The IB Diploma Programme offers four mathematics pathways: Mathematics: Analysis and Approaches (AA) SL and HL, and Mathematics: Applications and Interpretation (AI) SL and HL. Both cover number and algebra, functions, geometry and trigonometry, statistics and probability, and calculus, but their approaches differ.
| Course | Main emphasis | Common source of difficulty |
|---|---|---|
| Math AA | Algebraic techniques, reasoning, functions, calculus, and abstract problem-solving | Insecure algebra, difficulty recognizing methods, or weak logical working |
| Math AI | Modelling, statistics, real-world contexts, interpretation, and technology | Difficulty translating contexts, selecting models, interpreting output, or explaining results |
The official IB Diploma mathematics overview confirms that both subjects are available at SL and HL. The Math AA subject brief shows that AA includes a non-technology Paper 1, while the Math AI subject brief states that technology is permitted in all AI external assessments.
Neither course is simply “easy math” or “hard math.” A capable student may be poorly matched to a course's style, particularly if prior attainment and university plans were not considered when choosing it.
Identify what “I don't understand” means
A low test score does not reveal the underlying problem. Ask calm, specific questions:
- Which topic became confusing first?
- Can you follow an example but not begin a new question?
- Do algebra or calculator errors undermine the correct method?
- Do you run out of time?
- Are contextual questions difficult to interpret?
- Do you avoid asking questions in class?
The answers usually indicate one of four difficulties.
| Type of difficulty | Typical sign | Appropriate response |
|---|---|---|
| Foundation gap | Fractions, algebra, graphs, or equations block current work | Rebuild the prerequisite skill first |
| Conceptual gap | The student copies steps but cannot explain them | Use a clearer explanation, visual example, or guided lesson |
| Application gap | Routine exercises are manageable, but unfamiliar IB questions are not | Practise varied questions and discuss method selection |
| Performance gap | Understanding disappears under timed conditions | Use short timed sets, calculator drills, and an error log |
Choose one recent test and label each lost mark as concept, method, accuracy, interpretation, or time. This produces a more useful diagnosis than saying the student is “bad at math.”
Speak to the teacher and set priorities
Contact the mathematics teacher before assuming that your child needs tutoring or should change courses. The teacher can compare classroom understanding, homework, assessments, and participation rather than judging from one result.
Ask which prerequisite skills are weakest, whether the problem affects one topic or the whole course, and whether your child understands examples but struggles with independent application. Confirm whether the current AA or AI level remains appropriate and request a short, prioritized action plan for the next two weeks.
The first target might be solving equations accurately, using the graphing calculator confidently, or completing three functions questions independently. One measurable target is more useful than a long list of weaknesses.
Build a sustainable practice routine
Long, irregular study sessions often increase frustration. Start with three or four focused sessions each week, each lasting approximately 30 to 45 minutes:
- Review one definition, method, or worked example.
- Complete two straightforward questions without notes.
- Attempt two or three IB-style questions.
- Mark the work and identify the first incorrect step.
- Record one action for the next session.
The aim is not to complete as many questions as possible. It is to repeat the cycle of understand, attempt, check, correct, and reattempt.
The IB Math AA resource hub and IB Math AI resource hub provide course-specific materials. The guide to revising IB Math AA and AI explains how to combine notes, practice, and error review.
Support without taking control
Checking every assignment, finding numerous resources, or repeatedly asking about grades can make a student feel monitored. Instead, agree on a weekly check-in focused on what was practised, what became clearer, and which question still requires help.
Ask your child to explain one idea in plain language. You do not need to understand the mathematics fully. If they cannot explain what a graph, derivative, probability, parameter, or model represents, their understanding may be procedural rather than conceptual.
Reading notes creates familiarity, but students also need to retrieve methods independently. The Math AA Questionbank and Math AI Questionbank allow practice to be narrowed by course and topic. Encourage your child to complete a small set, study the feedback, and reattempt a similar question.
RevisionDojo's 2026 State of Learning Survey, based on 2,975 completed responses from students and teachers, found that Math AA respondents reported an average predicted-grade increase from 4.5 to 5.0. Questionbank was selected as an impactful feature by 40.7% of students. These self-reported, observational findings do not establish that using a resource caused the reported improvement.
Know when additional help is appropriate
Consider individual support if your child follows a focused plan for several weeks but still cannot begin basic questions independently, becomes highly distressed, or has several prerequisite gaps that cannot be addressed in class.
A suitable tutor should understand the correct AA or AI course and SL or HL assessment demands. They should diagnose errors, set measurable targets, and gradually increase independence rather than simply demonstrate solutions. RevisionDojo's IB tutoring directory can help families find course-specific support.
Consider course changes carefully
Changing from AA to AI or from HL to SL may be appropriate, but not as an immediate response to one difficult unit. Consider the pattern of attainment, teacher recommendation, school deadlines, and intended university courses.
Universities can treat AA, AI, SL, and HL differently. The IB's mathematics course recognition guide illustrates how expectations vary by institution and degree. Always check current entry requirements for likely universities rather than relying on general claims about which course is “better.”
What parents should do next
Confirm the course, examine recent errors, speak to the teacher, and choose one or two priorities. Establish short, regular practice sessions and review progress after two or three weeks using completed questions and repeated-error patterns rather than feelings alone.
RevisionDojo can support this plan with course-specific Study Notes, Questionbank practice, Jojo AI explanations, and Tutors. Start with the relevant Math AA or Math AI hub, then use targeted questions and feedback to assess whether understanding and independence are improving.
