# Picnic Challenge

Activity Overview

Students find patterns to solve problems, explore functions, and graph linear functions on the coordinate plane.

Before the Activity

• See the attached PDF file for detailed instructions for this activity
• Print pages 31 - 35 from the attached PDF file for your class
• Study the calculator keystrokes
• During the Activity

Distribute the pages to the class.

• Understand the problem - find the combination of 6, 9, and 20 that adds to 50
• Formulate pattern rules for the problem
• Determine the number of patterns that repeat in a cycle
• Find the sum for each pattern rule
• Plot the results on a graph paper
• Find the largest impossible value and the combination that gives 50 as the sum
• After the Activity

Students complete the Student Activity pages and answer questions.

• Review student results
• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
