Lesson Introduction:
How can a
person save money when they text?
How will you
determine the price for each letter?
The phone
company introduces a new pricing format. Students are responsible for
collecting data to see if charging by the letter is more feasible. The phone
company will set up three tiers for their pricing.
- Tier 1 no charge for 10 letters of the
alphabet
- Tier 2 half price for 10 letters of the
alphabet
- Tier 3 full price for the last 6 letters of
the alphabet
Students are
to collect data to determine which tier to place each letter. They will also
determine how much to charge for letters in Tier 2 and 3.
Students will make a presentation of their
billing procedure in PowerPoint.
Task:
As a high-powered
texting individual, you have been invited to join a consumer research group.
Your input could determine the future costs of texting for all Americans.
Text 2 Text
Connections has decided to change the way we bill consumers for texting. Rather
than charge an expensive monthly fee, we have decided to charge by the letters
used in texting. The alphabet will be divided into three categories: Tier 1 will contain ten letters that will be
free of charge.
Tier 2 will
also contain ten letters but there will be a minimal charge for these letters.
Tier 3 will
contain six letters and will be double the cost of Tier 2.
Your
assignment, should you choose to accept it, would be to collect data to
determine which category to place all letters of the alphabet and what charges
should be applied to Tiers 1 and 2.
Remember, in
these tough economic times all Americans are counting on you to make informed
decisions and to keep their texting costs as low as possible
Students will
complete the assignment by completing the following steps:
- Collect and organize data and entered in MS
Excel spreadsheet.
- Make a prediction based on data collected
written on a MS Word document.
- Convert numbers from a fraction to decimal and
percent using an Excel spreadsheet.
- Display data in a frequency table and bar
graph using an Excel spreadsheet.
- Determine mean, mode, and median and which
measure of central tendency is best suited for analyzing data presented
this project.
- Add and round decimals to the nearest
hundredth using an Excel spreadsheet.
- Work collaboratively showing all seven
“Character Traits” for the good of the group.
- Use appropriate technology tools including a
calculator, cell phone, and computer
- Prepare a PowerPoint presentation.
Resources – List of technology
resources needed to complete the task.
Microsoft Word- State your prediction based on data collected.
MS PowerPoint- This will serve to showcase your presentation.
MS Excel- Convert numbers from a fraction to decimal and percent, display
data in a frequency table and bar graph, and add and round decimals to the
nearest hundredth.
Internet- Research other data plans from other companies.
Cell phone- Review typical text messages sent and received in the past.
Process - Overview of how the task will
be accomplished.
Students will
be arranged into groups of 3 or 4 being mindful of special needs students and
peer tutors. Additional assistance will be available through the use of Impact
teacher, computer lab specialist, and peer tutors.
Peer tutors
can also team up with EL students.
Special needs
students may also have an assigned aide assist them as well.
Students will collaborate
with their team to problem solve and be held accountable for their learning.
The teacher
will be able to take on the role of facilitator once the project commences.
Students will be encouraged to resolve their own differences before asking for
assistance.
Assessment:
Oral
Presentation-Interesting, well rehearsed with smooth delivery that holds
audience attention.
Workload- The
workload is divided and shared equally by all team members.
