Student Fit
Who should take MYP 3?
MYP 3 students building independence in multi-step problems and deciding where they need consolidation or challenge.
Learners who benefit from a structured plan alongside their current school lessons.
The starting check covers ratio, percentages, equation solving and interpreting coordinate graphs.
Students who want to explain their reasoning as well as improve calculation accuracy.
Syllabus Map
MYP 3 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.
Algebra & relationships
Use algebra to represent and solve connected conditions.
Graphs & modelling
Choose and interpret a model instead of only drawing it.
Geometry & trigonometry
Link diagrams, calculations and geometric arguments.
Statistics & probability
Evaluate evidence and represent uncertainty.
Suggested Topic Breakdown

Suggested coverage, matched to your school
Sampling, bias and reliable comparisons
Grouped data and suitable graphs
Measures of centre and spread
Scatter diagrams and lines of best fit
Two-way tables and sample spaces
Probability trees for simple combined events
Learning in practice
Investigate, explain and apply
A sample investigation
Investigate the sum of consecutive odd numbers. Organise cases, propose a general rule and support it with a diagram or algebra.
A real-world application
Compare two transport pricing models, find the break-even point and discuss when the chosen model stops being useful.
These are practice examples; your school sets the assessed tasks and their requirements.
Assessment
MYP 3 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.
- Prepare for MYP 4 by identifying whether standard practice or additional extended challenge fits the school pathway.
FAQ
Common questions about MYP 3
Practical answers about topics, school alignment and assessment for this MYP year.
Which grade is MYP 3 equivalent to?
MYP 3 usually corresponds to Grade 8 (Class 8). This is the common Grades 6–10 mapping; local year names and placement rules vary by school and country.
Is there one fixed MYP 3 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.
