The start of a spatial pattern of triangles is shown and described in a table. Students generate more of the pattern and describe the relationships algebraically.
Students answer questions about distance, speed and time, and identify an expression that describes the distance (kilometres) from the starting point in terms of time (minutes).
Students use given information to solve a story problem about paper deliveries and identify the correct algebraic equation for the answer. They also write an algebraic equation for a similar story problem.
