This online course allows students to review the math notions learned in 5th grade : operations on fractions and decimals, multiplication, division, powers of 10, volume, coordinate planes, algebraic thinking, unit conversion, line pltys and shape properties. The concepts are presented in the form of videos and small review exercises with immediate feedback. A final challenge completes the course.

This online course allows students to review some basic geometry concepts: area, perimeter, volume, plane figures, solids, units of measurement, angles, reference plane, decomposition of a figure, solids, scale, and geometric transformations. The concepts are presented through videos and short review exercises with immediate feedback. A final challenge completes the course.
