How is MYP Year 2 different from Class 7 in Indian boards?

MYP Year 2 covers similar topics to CBSE and ICSE Class 7, but the teaching approach is more investigation based. Students are asked to explore concepts before being told the formulas, and they are graded on four separate criteria rather than a single numerical mark. The actual content is roughly equivalent, with MYP including a bit more on transformations and international unit conversions.

Do MYP students need to memorise formulas?

Yes, for Criterion A tasks. But unlike some other systems, MYP also expects students to explain where the formulas come from and to apply them thoughtfully to real world contexts. Pure memorisation without understanding will not get a high grade.

Which textbook does my MYP Year 2 school use?

The most common textbooks are Haese Mathematics MYP 2, Oxford MYP Mathematics Year 2, and Cambridge Checkpoint equivalents. Ask your teacher which one your school uses so you can cross reference this sheet with the relevant chapters.

Is this sheet enough for the end of year MYP assessment?

This sheet covers formulas which corresponds to Criterion A mainly. For Criterion B you need investigation practice, for Criterion C you need to practise clear written mathematics, and for Criterion D you need real world application tasks. All four criteria together make up the full MYP assessment.

How do MYP grades work?

Each criterion is graded on a scale from 0 to 8, so the maximum total is 32. A simple conversion converts this total to the final MYP grade (1 to 7). Your teacher will use the official MYP grade boundaries to convert criterion totals to the final grade.

Does the IB Learner Profile affect maths grades?

The Learner Profile is not directly graded, but it shapes how MYP mathematics is taught and assessed. Being an inquirer, a thinker, a communicator and a reflective learner all translate into better performance across the four criteria, especially Criterion B and Criterion C.

A Formula Sheet That Works With the MYP Framework

$A parent in Zurich once wrote to me asking for 'the IB equivalent of a CBSE formula sheet'. Her daughter had just moved to an MYP school in Year 2, which is roughly the same as Class 7 in the Indian system, and she could not find a single document that listed the maths formulas for the year. All the resources she found were either full textbooks or lesson plans. I promised her I would put one together, and here it is.$

$MYP mathematics is organised into four strands rather than chapters. The four strands are Number, Algebra, Geometry and Trigonometry, and Statistics and Probability. Each strand is assessed against four criteria: Criterion A (Knowing and Understanding), Criterion B (Investigating Patterns), Criterion C (Communicating), and Criterion D (Applying Mathematics in Real Life Contexts). This framework means that knowing a formula is only one quarter of the picture. You also need to investigate why it works, communicate your solution clearly, and apply it to real situations.$

$This sheet respects the MYP philosophy by grouping formulas under the four strands and, where appropriate, pointing out which assessment criterion tends to focus on that formula. Use it alongside your textbook and classroom resources to strengthen Criterion A recall, and use the practice links to develop the other three criteria through problem solving.$

Strand 1: Number — Integer and Rational Operations

$Integer sign rules$

(+) \times (+) = +, \quad (-) \times (-) = +

(+) \times (-) = -, \quad (-) \times (+) = -

$Order of operations (BIDMAS / PEMDAS) : Brackets, Indices, Division and Multiplication (left to right), Addition and Subtraction (left to right).$

$Fraction arithmetic$

\frac{a}{b} + \frac{c}{d} = \frac{ad + bc}{bd}

\frac{a}{b} - \frac{c}{d} = \frac{ad - bc}{bd}

\frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd}

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

$Decimal to fraction: write the decimal as a numerator over a power of 10 and simplify.$

$\frac{p}{q}$

$The IB learner profile encourages students to be inquirers . When you meet a new number property, ask why it works rather than accepting it. For example, why does a negative times a negative give a positive? Ask your teacher to walk you through a number line based explanation.$

Strand 1: Number — Percentages and Ratios

$x\% = \frac{x}{100}$

$Percent of a quantity$

x\% \text{ of } Q = \frac{x}{100} \times Q

$Percentage change$

\% \text{ change} = \frac{\text{new} - \text{old}}{\text{old}} \times 100

$a : b$

$y = kx$

$y = \frac{k}{x}$

$\frac{6}{4} = 1.5$

Strand 1: Number — Powers and Scientific Notation

$a$

a^m \times a^n = a^{m+n}

a^m \div a^n = a^{m-n}

(a^m)^n = a^{mn}

(ab)^n = a^n b^n

\left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}

a^0 = 1

a^{-n} = \frac{1}{a^n}

$a \times 10^n$

$3450000 = 3.45 \times 10^6$

$IB MYP tests international unit conversions frequently, so knowing scientific notation is essential for handling very large or very small numbers like the mass of Earth in kilograms or the radius of a hydrogen atom in metres.$

Strand 2: Algebra — Expressions and Identities

$3x + 5x = 8x$

$a(b + c) = ab + ac$

$(a + b)(c + d) = ac + ad + bc + bd$

$Simple algebraic identities (introduced informally in MYP Year 2):$

(a + b)^2 = a^2 + 2ab + b^2

(a - b)^2 = a^2 - 2ab + b^2

(a + b)(a - b) = a^2 - b^2

$Substitution : to evaluate an expression, replace each variable with the given value, using brackets around negative substitutions.$

Strand 2: Algebra — Linear Equations and Inequalities

$Solving linear equations : isolate the variable using inverse operations.$

$Balance principle : whatever operation you apply to one side, you must apply to the other.$

$Word problem translation : * 'sum' means addition * 'difference' means subtraction * 'product' means multiplication * 'quotient' means division * 'is' or 'equals' means the equal sign$

$x > a$

$3, 7, 11, 15, \ldots$

Strand 2: Algebra — Coordinates and Linear Graphs

$(x, y)$

$Distance between two points (informal in MYP Year 2):$

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

$This is derived from the Pythagoras theorem.$

$y = mx + c$

$Gradient between two points :$

m = \frac{y_2 - y_1}{x_2 - x_1}

$y = k$

$x = k$

$A classic Criterion D application: given two data points, find the line that passes through them and use it to predict a third value.$

Strand 3: Geometry and Trigonometry — Angles and Triangles

$180°$

$Exterior angle theorem : the exterior angle equals the sum of the two opposite interior angles.$

$n$

S = (n - 2) \times 180°

$Regular polygon interior angle :$

\text{each angle} = \frac{(n - 2) \times 180°}{n}

$c^2 = a^2 + b^2$

$Triangle classification * By sides: equilateral, isosceles, scalene * By angles: acute, right, obtuse$

$180°$

Strand 3: Geometry and Trigonometry — Perimeter, Area and Volume

$Perimeter of a polygon : sum of all sides.$

$Area formulas$

\text{square: } A = s^2

\text{rectangle: } A = l \times w

\text{triangle: } A = \frac{1}{2} \times b \times h

\text{parallelogram: } A = b \times h

\text{trapezium: } A = \frac{1}{2}(a + b) \times h

\text{circle: } A = \pi r^2

$C = 2\pi r = \pi d$

$V = \text{base area} \times \text{height}$

$Specific volumes$

\text{cube: } V = s^3

\text{cuboid: } V = l \times w \times h

\text{cylinder: } V = \pi r^2 h

$6s^2$

$= 100$

$\pi \approx 3.14$

Strand 3: Geometry and Trigonometry — Transformations

$MYP introduces four basic transformations in Year 2.$

$Reflection : a mirror image of a figure across a line. The distance from any point to the line equals the distance from its image to the line.$

$Rotation : turn about a fixed point by a given angle. Specify the centre, angle and direction (clockwise or anticlockwise).$

$\binom{a}{b}$

$k$

$Congruent vs similar * Congruent: same size and same shape (scale factor 1). * Similar: same shape, possibly different size.$

Strand 4: Statistics and Probability — Measures of Centre and Spread

$\bar{x} = \dfrac{\sum x_i}{n}$

$Median : the middle value when data is arranged in order. For an even count, average the two middle values.$

$Mode : the most frequently occurring value. A dataset may have one mode, no mode, or multiple modes.$

$Range : maximum value minus minimum value.$

$Frequency table summarises data by listing each value (or class interval) alongside its frequency.$

$Histogram and bar chart : visual representations. Use a histogram for continuous data, a bar chart for categorical data.$

$Stem and leaf plot : a compact way to show data while preserving individual values.$

$Criterion D tip : whenever you compute a statistic, ask whether it accurately represents the data. Outliers can distort the mean but leave the median unaffected. Explaining this in your write up shows strong application of mathematics in real contexts.$

Strand 4: Statistics and Probability — Basic Probability

$Probability of an event$

P(E) = \frac{\text{number of favourable outcomes}}{\text{total number of outcomes}}

$0 \le P(E) \le 1$

$P(\text{not } E) = 1 - P(E)$

$\{1, 2, 3, 4, 5, 6\}$

$A$

P(A \text{ and } B) = P(A) \times P(B)

$A$

P(A \text{ or } B) = P(A) + P(B)

$The MYP learner profile encourages students to be reflective . When solving probability problems, check whether events are really independent or whether you need a tree diagram to map the outcomes properly.$

The MYP Assessment Criteria: Why Formulas Alone Are Not Enough

$Unlike CBSE and ICSE, the MYP grades students on four separate criteria. Here is what each one looks for, and how to use this formula sheet for each.$

$Criterion A — Knowing and Understanding This is pure recall and direct application. Test questions ask 'calculate', 'evaluate', 'find'. This formula sheet is directly helpful for Criterion A.$

$Criterion B — Investigating Patterns Tasks ask you to spot a pattern in a sequence or diagram, describe the rule, generalise it algebraically, and verify it. This sheet helps less here; you need actual investigation tasks. The formulas you derive in an investigation often get added to your personal formula sheet at the end.$

$\subseteq$

$Criterion D — Applying Mathematics in Real Life Contexts You take a real world scenario and apply maths to make a decision or prediction. This sheet gives you the tools; Criterion D asks you to choose the right tool and use it well.$

$A student aiming for a level 7 or 8 on MYP mathematics needs to practise all four criteria, not just one. Use this sheet for Criterion A revision, and use dedicated investigation tasks for the other three.$

How to Use This Sheet

$Here is a practical two week revision plan before any summative assessment.$

$Two weeks out : read each strand section carefully. For every formula you do not recognise immediately, mark it with a star.$

$One week out : make flashcards of starred formulas. Review them twice a day for five minutes each.$

$Four days out : attempt practice questions for each strand on the SparkEd Class 7 IB practice hub . Whenever a formula comes up that you did not have memorised, mark the flashcard for extra review.$

$Two days out : do a mixed mock task covering all four strands. Time yourself.$

$Exam day : scan the relevant strand sections ten minutes before walking in. Do not try to learn anything new on the day of the test. Trust your preparation.$

$For structured investigation practice aligned to Criterion B, and communication exercises for Criterion C, ask your teacher for past MYP tasks from your school's shared resources.$
