# Math Trek Grade R to 3

## Modules Overview

Math Trek R, 1, 2, 3 is a comprehensive curriculum-based program which covers the mathematics knowledge and skills generally taught in grades Kindergarten, 1, 2 and 3. It is a multimedia program with sound, animation and graphics, which provides exploratory activities. It is organized under the strands typically found in the grade 1, 2 and 3 mathematics curriculum:

Number Sense and Numeration;

Patterning and Algebra;

Geometry and Spatial Sense;

Data Management and Probability;

Measurement.

It may be used on standalone computers or on a network on Windows computers.
