Discovering mathematics

This module provides a gentle start to the study of mathematics. It helps you integrate mathematical ideas into everyday thinking and builds confidence in using and learning mathematics. It covers statistical, graphical, algebraic, trigonometric and numerical concepts and techniques and introduces mathematical modelling. You’ll learn skills required to study further mathematics or to successfully study many other subjects, such as business, computing, economics, education, humanities, science, social science and technology.

What you will study

In order to study this module successfully you should expect to be actively doing mathematics, rather than just reading it. You will also be encouraged to develop skills in interpreting and explaining mathematics, and this aspect will be assessed in some of the assignment questions.

Providing you have the appropriate background knowledge, you should expect to study for about eight hours a week. Many of the topics covered in the module depend on your understanding of topics in earlier units. So, if you have not fully understood earlier material, you may find later material more difficult and time consuming. This is particularly true of graphs, formulas and algebra. Naturally, the study time required for the module tends to increase before an assignment deadline.

You can find the full content list on the Open mathematics and statistics website.

You will learn

Successful study of this module should begin to develop your skills in working with mathematical concepts and using them to solve problems.

You will learn about:

• key ideas in mathematics, including some statistics, algebra, geometry and trigonometry
• mathematical vocabulary and notation introduced and developed in the module
• selection and use of mathematical techniques for solving problems
• interpretation of results in the context of real life situations
• simple mathematical arguments
• how to explain mathematical ideas from the module in writing
• development of skills in learning mathematics
• use of relevant ICT tools for learning and for working on mathematical problems
• describing problems mathematically
• analysing mathematical reasoning.

The module contains many real world contexts such as journey planning, glaciers, supply and demand, depreciation, poverty levels, chance events, and medical conditions (such as cancer), to help illustrate mathematical topics.

Professional recognition

This module is often accepted as an equivalent qualification to GCSE grade 4 in mathematics by teacher training institutions, but always at the discretion of each institution. So, if you hope to use it for this purpose, you are advised to check as early as possible with your chosen teacher training institution(s).

Entry requirements

There is no formal pre-requisite study.

You can check you’re ready for MU123 and see the topics it covers here.

Talk to an advisor if you’re not sure you’re ready.

Preparatory work

You should aim to be confident and fluent with the concepts covered in the Are you ready? quiz here, and follow the advice in the quiz.

What's included

You’ll have access to a module website, which includes:

• a week-by-week study planner
• course-specific module materials
• audio and video content
• relevant computer software and associate guidance
• assessment details, instructions and guidance
• online tutorial access
• access to student and tutor group forums.

You’ll be provided with printed books covering the content of the module, including explanations, examples and activities to aid your understanding of the concepts and associated skills and techniques. In addition, you will have a printed Module Guide and Handbook.

You will need

A scientific calculator. We recommend any Casio scientific calculator with ’natural display’, as these enable you to key in calculations in the same order as they usually appear in written text, and have a two-line display so that you can see both your calculation and the answer. Some instructions for using the Casio fx-83ES, and compatible models, are provided in the study materials. Any other scientific calculator is also acceptable provided that you know how to use it before the module starts, and you have access to the appropriate calculator manual (these are often available to download from the manufacturer’s website). Please note that you do not need to have a graphics or programmable calculator to study this module.

(If you have studied Science, technology and maths Access module (Y033), you can use the calculator from that module providing you have access to the manual.)

Computing requirements

• Primary device – A desktop or laptop computer. It’s possible to access some materials on a mobile phone, tablet or Chromebook; however, they will not be suitable as your primary device.
• Peripheral device – Headphones/earphones with a built-in microphone for online tutorials.
• Our OU Study app operates on supported versions of Android and iOS.
• Operating systems – Windows 11 or latest supported macOS. Microsoft will no longer support Windows 10 as of 14 October 2025.
• Internet access – Broadband or mobile connection.
• Browser – Google Chrome and Microsoft Edge are recommended. Mozilla Firefox and Safari may be suitable.

Teaching and assessment

Support from your tutor

You’ll get help and support from an assigned tutor throughout your module.

They’ll help by:

• marking your assignments and offering detailed feedback to help you improve
• providing individual guidance, whether that’s for general study skills or specific module content
• guiding you to additional learning resources
• facilitating online discussions between your fellow students in the dedicated module and tutor group forums.

Online tutorials run throughout the module. Where possible, we’ll make recordings available. While they’re not compulsory, we strongly encourage you to participate.

Assessment

The assessment details for this module can be found in the facts box.

The first interactive computer-marked assignment (iCMA), covering Unit 1, is to be submitted about two weeks after the start of the module. The first TMA is to be submitted about a month after the start.

TMA questions typically involve calculating, creating and/or interpreting a graph or diagram, using algebra, and explaining your work and conclusions. The latter is one factor that makes this a university-level module and it is a new approach for some students, who may find it challenging initially. Some TMAs may also include a short question covering a wider aspect of studying maths.

As there is no examination, the end-of-module assessment (EMA) aims to consolidate your learning across different aspects of the module. It covers the whole of the module, and is compulsory if you wish to pass the module.
