SkiQuations is a collection of multilevel activities that focus on graphs of linear equations. Students enter a ski environment with activities situated on a hill, arranged so that the difficulty of the activities increases with the slope of the hill. The interactive activities make learning fun and motivate students to spend the extra time required to master a topic.

This program is designed to encourage students to take responsibility for and manage their own learning. Students can assess their level of understanding by selecting activities at varying levels on the hill until they have found an appropriate starting point for their review. Students can also choose difficulty levels within each activity.

10 Activities cover skill areas including:
- specifying x and y-coordinates on the xy-plane
- plotting points on the xy-plane from a table of values
- calculating y as a function of x and creating a table of values
- rearranging equations from the form
Ax + By + C = 0 to y = mx + b and vice versa
- communicating solutions in established mathematical form
- graphing a line from a given table of values or from a given equation
- determining the slope of a line segment
- investigating the geometric significance of m and b in
y = mx + b
- recognizing the graph characteristics of slope properties such as direction, positive or negative rate of change, and steepness
- selecting the equations of straight lines from a given set of equations of linear and non-linear relations
- identifying equations of lines in slope-intercept, standard, and other forms
- matching linear and non-linear graphs to their equations
- finding an equation given a line
- identifying equations with graphs that pass through a given point
- investigating the properties of the slopes of line segments as related to parallelism and perpendicularity
identifying equations of parallel lines given the equation of a line
- finding the equation of a line given two points, slope and y-intercept, or slope and a point on the line
