Communication approaches can affect the learning of numeracy processes and skills.

Mathematical proficiency requires a student to be able to communicate in a way that meets the goals of mathematics instruction including solving mathematical problems, communicating and reasoning mathematically, making mathematical connections, and modelling and interpreting practical situations. However, this can be affected by approaches a teacher use in a Math class.

Therefore, effective learning of numeracy skills should incorporate representation, listening, reading, discussion and writing. A teacher may employ group discussions, put mathematical questions in a context that learners are familiar with, encourage students to express their opinions, guide learners to understand instructional material and encourage them to write or work out mathematical activities to help students develop mathematical skills.
