Numeracy at Work - Math Series

Preparing Indigenous learners for Apprenticeship and Employment

There are 5 booklets in the Numeracy at Work series. The booklets are designed for learners entering an apprenticeship program or preparing for the workforce.  Learners are encouraged to complete a booklet in a career they are interested in or they could try all the booklets to investigate what careers interest them.  Every booklet concentrates on math concepts and skills needed in a chosen career.

The OALCF are the guidelines used to establish math concepts and skills at Level 1 and Level 2, as some career paths are more advanced learning of math concepts.
