As of September 2020/January 2021 the mathematics guide which has been around for six years will no longer be current. If you want to save yourself the time of reading every . single . page, read on as (most of) the changes are listed here.

__Mathematics across the IB continuum__

Page 6 shows an updated figure outlining the **transition** from Primary Years Programme to the Middle Years Programme standard and extended courses and culminating in the new Diploma Programme courses of Analysis and Approaches, and Applications and Interpretation (standard and higher level). From this it seems that students' DP choices will not be restricted by whether they were in a standard or extended class in MYP4/MYP5.

__Conceptual Understanding__

Two of the **related concepts** have been removed and replaced. 'Justification' and 'Measurement' have been replaced by 'Approximation' and 'Validity' (page 20 in the old guide, page 18 in the new).

Pages 19 - 20 (page 21 in the old guide) show that six out of the seven example **statements of inquiry** have been reworded. Some to accommodate the new related concepts while others refer to the global context, key concept and related concept(s) more explicitly.

__Mathematics framework__

Pages 22-23 include a new recommended **prior learning** list outlining the topics and skills that students should be familiar with before starting the Middle Years Programme.

The four** branches of mathematical study** have been adapted to have a focus on *reasoning*:

Previous guide branches: number, algebra, geometry and trigonometry, statistics and probability.

New guide branches: numerical and abstract reasoning, thinking with models, spatial reasoning, and reasoning with data.

__Topics and skills ____(t__his has changed a few times since the original blog post so the updated framework can be found __here__.)

The topics and skills on pages 23 - 29 of the new guide differ slightly to those in the previous guide (pages 25 - 31).

**REMOVED:** Topics/skills on previous guide which do not appear in the new guide:

Ordering numbers

Representing numbers as products of their prime factors

Converting currencies

Algebraic fractions

Solving non-linear inequalities

Compound shapes

Line graphs

**MOVED:** Topics/skills which have moved from Standard to Extended:

Domain and range

Transforming functions

Linear programming

Histograms

Enlargement around a given point, by a rational factor

Converse of Pythagorasâ€™ theorem

**MOVED: **Topics/skills which have moved to enrichment (and therefore not on e-Assessment):

Exponential functions

Logarithmic functions (including ln and e)

Inverse functions

Composite functions

Number bases

Three dimensional coordinate geometry

Vector notation and vector spaces

Trigonometric identities

Radians

Unit circle

Arithmetic and geometric series and summation

**NEW: **Topics/skills on the new guide which did not appear in the previous guide:

__MYP 1 - 3__

Time zones, clocks and timetables

Flowcharts

Forming equations

Surface area and nets

Bar charts, stem and leaf, pictograms

Data visualizations and infographics

Limitations and context in statistical enquiry

Qualitative handling of probability

__Standard__

Representing and solving compound and double inequalities

Negative exponents

Mappings

Function notation

Tessellations

Bearings

Data manipulation and misinterpretation

Cumulative frequency graphs

Correlation, qualitative handling

Relative frequency

Response rates

__Extended__

Using technology to find values with logarithmic functions

Upper and lower bounds

Networks - calculating pathways and weighted pathways

Volume and capacity of additional shapes

Identical representation of transformations

Correlation, quantitative handling, using technology

Dependent events

__Enrichment__

Exponential equations

Rationalizing the denominator

Sigma notation

Convergence and divergence

Fractals

Dilation

Inscribing and circumscribing shapes

Polar coordinates

Area of a triangle rule

Equation of a circle with center at the origin

Manual calculator of standard deviation, correlation coefficient

Frequency polygons

Covariance

Interpolation and extrapolation

Confirmation bias

Counting principles

Combinatorics

Permutations

Factorials

Geometric mean

Regression - interpretation of results

Note: some of the above may appear implicitly in either guide and therefore may not be considered new or removed by all. The guide states clearly that topics/skills listed within extended or enrichment can be taught to standard. In addition, all topics and skills are said to be examples of what students could study. All this to say there is still considerable flexibility by each school and teacher, responding to the needs of their class.

How are these changes going to reflect in your school's subject overview? Will you be making subtle new inclusions in certain units or taking this opportunity to completely review your taught curriculum?
