Sources of help If you need to brush up on your maths skills, the Maths Help website at http://mathshelp.open.ac.uk/ is a good place to start. It includes the following units:

**Module 1: Numbers, units and arithmetic**

This is particularly useful for the ‘Basic arithmetic’ and ‘Units, conversions, area and volume’ sections of the T213 maths quiz.

**Module 2: Rounding and estimation**

This is particularly useful for the ‘Basic arithmetic’ section of the T213 maths quiz.

**Module 3: Ratio, proportion and percentages**

This is particularly useful for the ‘Ratios, proportion and percentages’ section of the T213 maths quiz.

**Module 4: Squares, roots and powers**

This is particularly useful for the ‘Powers and scientific notation’ section of the T213 maths quiz.

**Module 5: Diagrams, charts and graphs **

This is particularly useful for the ‘Tables and charts’ and ‘Graphs’ sections of the T213 maths quiz.

**Module 6: Language, notation and formulas**

This unit will help you to set out your work clearly and use mathematical language correctly. If you are not sure about using and rearranging mathematical formulae then try working through this unit.

**Module 7: Geometry**

If you are registered as an OU student and have been allocated a personal identifier then the following resources may also be useful:

The Maths Skills section at http://www2.open.ac.uk/students/skillsforstudy/doc/maths-skills.pdf covers similar material as above, but is more focussed on science applications.

The OU library gives you access to a series of HELM workbooks (Helping Engineers Learn Maths). These cover a much wider range of topics than is needed for T213 and will be particularly useful for students studying towards an engineering qualification. You can find the workbooks at http://www.open.ac.uk/libraryservices/filestore/e-docs/helm/pages/helm_workbooks_jan2008.html
