Student Fit
Who should take MYP 4?
MYP 4 students following their school’s mathematics or extended mathematics pathway.
Learners who benefit from a structured plan alongside their current school lessons.
I review linear equations, graph interpretation, index laws and right-triangle methods, then agree on the appropriate depth.
Students who want to explain their reasoning as well as improve calculation accuracy.
Syllabus Map
MYP 4 syllabus & learning plan
IB MYP is a flexible framework, not a single worldwide year-by-year syllabus. The topics below are a suggested tutoring sequence; lessons follow your school's unit plan, prior learning and assessment criteria.
Equations & functions
Select methods for linear and non-linear relationships.
Geometry & trigonometry
Combine geometric facts to solve multi-step problems.
Statistics & probability
Explain what a statistical model can and cannot show.
Investigations & applications
Develop a defensible argument from evidence.
Suggested Topic Breakdown

MYP 4 Learning Plan
Suggested coverage, matched to your school
Choosing examples and systematic tables
Stating and checking a generalisation
Supporting a rule with mathematical reasoning
Defining quantities and assumptions in a model
Evaluating accuracy and limitations
Communicating with linked diagrams, graphs and notation
Learning in practice
Investigate, explain and apply
A sample investigation
Investigate a family of quadratic graphs by changing one parameter. Describe what changes, test exceptions and justify a general statement.
A real-world application
Model the cost and capacity of a container design, compare alternatives and explain the limits of the measurements used.
These are practice examples; your school sets the assessed tasks and their requirements.
Assessment
MYP 4 assessment & investigations
1
Criterion A — choose and use suitable mathematics in routine and unfamiliar problems.
2
Criterion B — explore examples systematically, identify a rule and support your conclusion.
3
Criterion C — connect notation, diagrams, tables and explanations so your reasoning is understandable.
4
Criterion D — select mathematics for a practical situation, interpret the result and evaluate its usefulness.
5
School tasks use the relevant year-level descriptors. Tutoring feedback follows the task rubric; the school awards official grades.
6
Preparation focuses on school-based tests, investigations and applications; this year is not presented as a separate IB external mathematics examination.
How Classes Run
Teaching plan
- Review the school unit plan, recent marked work and the student’s own explanation of a difficult question.
- Teach a priority concept through a worked example, then fade support as the student attempts a related problem.
- Use short independent practice and an error log to check whether learning lasts beyond the lesson.
- Practise an investigation or application with feedback on reasoning and presentation, while the student remains the author.
- Build toward MYP 5 through cumulative revision and increasingly independent work with all four assessment criteria.
FAQ
Common questions about MYP 4
Practical answers about topics, school alignment and assessment for this MYP year.
Which grade is MYP 4 equivalent to?
MYP 4 usually corresponds to Grade 9 (Class 9). This is the common Grades 6–10 mapping; local year names and placement rules vary by school and country.
Is there one fixed MYP 4 syllabus?
IB MYP is a flexible framework, not a single worldwide year-by-year syllabus. The topics below are a suggested tutoring sequence; lessons follow your school's unit plan, prior learning and assessment criteria.
How do you match lessons to my school?
Share the unit outline, textbook chapter, task rubric and a recent test. I identify the current topic, prerequisite gaps and the depth your teacher expects.
Is this Standard Level or Higher Level?
SL and HL are DP course labels. MYP uses mathematics and extended mathematics pathways; the school’s provision and the student’s readiness determine the appropriate challenge.
How will my progress be assessed?
I use short diagnostic questions, independent practice and investigations alongside your school’s rubric. There is no separate external IB mathematics exam for each early MYP year.
What should I bring to an introductory session?
Bring the school topic list, one recent marked assignment and one question you found difficult. The paid session combines a learning check with focused teaching and a suggested plan.
