How DIY Maths can help you

If you're studying a programme that requires competency in maths, the modules in DIY Maths can help you to refresh your skills or study new content. Within a module, you’ll find video lessons, content links, games, downloadable worksheets, practice quizzes, and links to 24/7 maths tutors. Every module also provides search tips, so you can find your own information to supplement your learning.

How to get the most out of DIY Maths

- If you can, keep a journal just for maths.
- Work through all the resources on the page from top to bottom. Take notes and try problems as you go. As you finish each activity, write about what you learned in your journal.
- If you find that you don't quite understand the concepts, use the search terms in the orange box on the righthand side of the page to search for more information.
- If you need assistance, you can get online 24/7 help at SOS Math (link in purple box on right), you can talk to your instructor, or you can make an appointment at any of Unitec's Student Learning and Achievement centres (see footer of page). If you've kept a journal, bring it to your appointment.
