Mathville SkiQuations has ten multilevel learning activities arranged in order of difficulty on a ski hill, so that students can find their own level and work their way up gradually, until they've mastered the topic. Later, when it's time to review, they can hit the slopes and swoosh through a few practice runs to regain their expert form.

Mathville SkiQuations Topics covered include:

• plot points on the xy-plane
• fill in and plot from tables of values
• rearrange standard and point-intercept forms
• find slopes and intercepts
• find equations from graphs

find equations given 2 points, slope and y-intercept, or slope and a point
