Material
 Background
Information:
This RWLO outlines an
activity where students view cell phone price
structures through an algebraic lens. Data will be obtained from a
current list of cell phone providers offering comparable services and
features. Each group of 23 students will examine data, determine the
rule and represent the rule as an algebraic expression. Students will
work together, but submit results independently. Independent
explanations and conclusions will make each student submission unique.
 Student Directions:
 Obtain a Student Instruction
Worksheet.
 As a group, gather
information about the cell phone providers’ packages closest to the
desired package. Record the providers and websites you use.
 Determine the independent
variable and dependent variables.
 Complete the table with
minutes, price, and other features for at least
two cell phone providers.
 Look at the tables to
determine a consistent relationship between two things (input and
output).
 Describe the relationship
verbally.
 Use the problem solving
template to translate the description to a formula that can be used
over and over again.
 Complete the Instruction
Worksheet individually and hand in.
