Product Description

This is a fun activity that helps students practice the concept of slope as rise over run.

Expert detective, Ray Radicand, is shadowing Mr. M. for the day. We know that Mr. M. started at his home. From there, students will use the clues Ray left in the form of linear equations to determine the places Mr. M. travelled.

Students will identify the slope in the equation, and then count out that slope on the grid and draw a line segment to discover each of Mr. M.’s stops.

The slopes can go in either direction from their starting point, so students will need to understand the idea of counting slope “up and then over” as well as “down and then over.” There are lines with no slope and undefined slopes as well.

Each location is marked by a dot in the middle of the square. In order for a location to be considered an actual stop the line must go directly through this dot. No line will pass through the dot to go to the other side of the business; once you get to the business, your line segment should stop.

When they have completed all 15 equations, students will have a list of all the places Mr. M. visited while we was being shadowed.

The Case of the Mixed Up Pawn Shop is a fun follow-up to this activity where your students practice using slope-intercept form to graph lines!
