### Success in Maths for Teaching

Educators require a basic knowledge of numbers, algebra, measurement, chance & data and space.

Current students can access the readiness test (**UConnect username and password required**) which is a self-test
that will help you decide the level of support you may need in these areas. It should take about half an hour to complete.

Current students can also access refreshment materials which provide a review of basic mathematical skills with examples and activities.

There are also a number of videos designed to assist you with this refreshment material.
