Discovering mathematics

Qualification dates
Start End

This key introductory OU level 1 module provides a gentle start to the study of mathematics. It will help you to integrate mathematical ideas into your everyday thinking and build your confidence in using and learning mathematics. You’ll cover statistical, graphical, algebraic, trigonometric and numerical concepts and techniques, and be introduced to mathematical modelling. Formal calculus is not included and you are not expected to have any previous knowledge of algebra. The skills introduced will be needed if you plan to study more mathematics modules, such as Essential mathematics 1 (MST124), and are also required in other areas, such as computing, economics, science, technology, social science, humanities, business and education.

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.

Samples of the study materials, including example assessment questions, are available from our MathsChoices website.

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 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 sometimes accepted as an acceptable equivalent qualification to GCSE grade C 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.

You can find out which module is your best starting point in mathematics 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

A computing device with a browser and broadband internet access is required for this module. Any modern browser will be suitable for most computer activities. Functionality may be limited on mobile devices.

Any additional software will be provided, or is generally freely available. However, some activities may have more specific requirements. For this reason, you will need to be able to install and run additional software on a device that meets the requirements below.

A desktop or laptop computer with either an up-to-date version of Windows or macOS.

The screen of the device must have a resolution of at least 1024 pixels horizontally and 768 pixels vertically.

To join in the spoken conversation in our online rooms we recommend a headset (headphones or earphones with an integrated microphone).

Our Skills for OU study website has further information including computing skills for study, computer security, acquiring a computer and Microsoft software offers for students.

Teaching and assessment

Support from your tutor

You'll have a tutor who will help you with the study material and mark and comment on your written work, and who you can ask for advice and guidance. Your tutor can also provide additional assistance with your study skills, especially if you're new to OU study.

Tutorials are designed to aid student success by providing help and guidance with your studies, including hints and tips to improve your understanding. You are encouraged to attend as many as you can – whether face-to-face or online they are an informal way to ask questions and to feel part of a student community.

We aim to provide face-to-face tutorials in a range of locations students can travel to, though we cannot guarantee availability close to where you live. An online alternative, covering similar content, is usually provided, typically with a recording of at least one such online tutorial being made available.

Student numbers on the module, and where tutors are based, will affect which tutor may lead a particular tutorial, the locations of face-to-face tutorials, and what online alternatives are offered.

Contact us if you want to know more about study with The Open University before you register.

Assessment

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

You can choose whether to submit your tutor-marked assignments (TMAs) on paper or online through the eTMA system. You may want to use the eTMA system for some of your assignments but submit on paper for others. You may also submit the end-of-module assessment (EMA) online or on paper. This is entirely your choice.

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.

If you have a disability
