Linear Functions Activity for 8th Grade Math

“The Mystery of the Lost Treasure: A Linear Functions Adventure” is an 8th grade math project on linear functions. Students play math detectives, identifying slopes and intercepts and working with linear equations to solve the mystery of the lost treasure.

What’s included

• 15 story-driven problem cards that have students apply linear functions in different contexts
• A full-color illustrated map of the fictional Lineara Island, the visual aid for the quest
