Year 2 is an important point in the MYP mathematics journey. Students are ready to work with more formal language and more demanding representations, but they still need lessons that make the ideas visible, give them time to practise and show why the mathematics matters. The IB MYP Year 2 Mathematics slidedecks are designed around that balance.

The collection contains 55 lesson decks across six connected units: Rational Numbers and Percentages; Algebraic Expressions and Equations; Proportional Reasoning and Linear Relationships; Geometry, Area and Volume; Statistics and Data Literacy; and Probability and Simulation. The folders follow a clear 2.1 to 2.6 sequence, making it straightforward to find a lesson while keeping the larger year plan in view.

A coherent Year 2 progression

The sequence begins with directed numbers, fractions, decimals, percentages and financial contexts. Students then move into algebraic vocabulary, simplifying and expanding expressions, factorising, equations, inequalities, formulae and algorithms. Proportional reasoning leads naturally into unit rates, best buys, direct proportion, ratio, speed, gradient and linear models.

The geometry unit applies reasoning to parallel lines, circles, area, surface area, volume, nets, three-dimensional visualisation and metric conversions. Statistics then develops data literacy through populations and samples, sampling bias, grouped frequency tables, stem-and-leaf diagrams, averages, spread, comparisons, scatter graphs and infographics. The year concludes with probability and simulation: sample spaces, combined outcomes, Venn and tree diagrams, relative frequency and the informal law of large numbers.

That order is useful because it revisits the same habits in different mathematical settings. Students interpret signs in number, use notation in algebra, compare rates, justify geometric relationships, question data and evaluate probability models. The mathematics changes, but the expectation to represent, reason, communicate and reflect remains consistent.

What is inside a typical deck?

Each deck follows a dependable lesson rhythm that students can learn quickly:

Learning objectives: the opening focus states what students should be able to do and identifies the relevant MYP key concept, related concepts and criteria.
Concept and method slides: new ideas are introduced through definitions, diagrams, examples, equations and step-by-step methods.
Worked examples: solutions make reasoning visible and give students a model for communicating their own work.
Practice: tasks move from accessible examples to independent application, including error analysis and find-and-correct prompts.
Real-world connections: lessons connect mathematics to temperature, elevation, shopping, construction, polling, school decisions, games and other familiar contexts.
Inquiry activities: students test claims, create examples and counterexamples, design fair surveys or games, and justify conclusions.
Exit tickets: short closing checks combine calculation, explanation and reflection so teachers can see what students understand before the next lesson.

The repeated structure supports classroom flow without making the mathematics repetitive. Students know where to look for the method, where to try it, where to question it and where to explain what they have learned.

Explicit mathematics with room for inquiry

MYP inquiry works best when students have enough mathematical knowledge to investigate a meaningful question. These decks make that knowledge explicit before asking students to use it. A lesson on directed numbers builds the number-line language needed to compare negative values. A lesson on algebraic notation clarifies variables, coefficients, constants and terms before students translate words into expressions. A lesson on sample spaces establishes organised lists, tables and tree diagrams before students judge whether a game is fair.

Once the foundations are in place, students have opportunities to think beyond a single answer. They can investigate whether a statement is always, sometimes or never true, design a fair survey, find examples of parallel lines in their environment, compare the value of different packs or invent a two-stage probability game. These tasks develop mathematical communication and justification alongside procedural fluency.

Real-world contexts that support understanding

The contexts are chosen to give the mathematics a reason to matter. Directed numbers describe temperature, elevation and movement. Unit rates help students compare pack sizes and make informed choices. Linear relationships model changing quantities. Geometry connects to fences, circles, packaging, construction and measurement. Sampling and bias invite students to question how evidence is collected, while probability connects to game design and fairness.

These contexts also encourage a useful MYP question: What does the answer mean in this situation? Students are prompted to include units, explain assumptions, compare representations, identify limitations and decide whether a conclusion is reasonable. That habit is more valuable than treating every exercise as a calculation detached from its purpose.

Assessment and reflection are built in

The decks help teachers gather evidence throughout an ordinary lesson. Objectives make the intended learning visible. Practice reveals fluency and misconceptions. Worked solutions support discussion and self-checking. Inquiry tasks show how students investigate patterns, communicate and apply mathematics. Exit tickets provide a quick decision point for the next lesson.

The final reflection is deliberately short. Students may explain how a number line prevents comparison errors, which algebra word helps them read an expression, how to choose a sampling method or why a complete sample space matters. These prompts make mathematical thinking visible rather than reducing success to a correct final answer.

How to use the Year 2 repository

Start with the curriculum map to understand how Year 2 fits into the wider MYP mathematics progression.
Open the Year 2 slidedeck repository and choose the unit folder that matches your current sequence.
Use the objectives and MYP focus to frame the lesson, then pause at practice, error analysis and inquiry slides rather than presenting every slide without discussion.
Use the worked solutions and exit ticket to decide whether students are ready to extend the idea, need another representation or would benefit from a short retrieval task.

The decks are ready to teach, but they are also designed to be adapted. Add local examples, familiar data, language support, technology or extension questions where your class needs them. The consistent lesson architecture gives teachers a reliable starting point; the varied problems, contexts and inquiries give Year 2 students the opportunity to become more independent mathematical thinkers.
