Stacking Paper Tasks

From Proportional Reasoning to Linear Relations

Introduce the concept of a proportional linear relationship (direct variation) and a linear relationship with an initial value (partial variation) while discovering the formula for slope. The journey continues as students will intuitively solve for the initial value or y-intercept as we scaffold towards the algebraic representation.

The collection of three tasks included in this multi-touch book for students range from Middle School to Lower Secondary Mathematics courses.
