Fractions, Percents, and Decimals

WebQuest

Introduction

This project is for 7th or 8th grade math students and serves as a conclusion to the Number Relationship Unit. You will be converting fractions to decimals to percents, and percents to decimals to fractions. The main goal of this WebQuest is to plan a pizza party for your class. You will be responsible for: calculating how much pizza and other supplies you will need, providing entertainment, and making sure accommodations are made for everyone. You will be required to research pizza shops, supermarkets, and other businesses to determine the best value for your budget.

You will work in groups of four and everyone will be assigned a role. There will be two researchers, one data collector and one recorder/presenter. Everyone is responsible for the group; you will all verify accuracy of each others job. The group that effectively uses the budget will be rewarded the pizza party. So, get to work and good luck!

Pennsylvania Curriculum Standards

2.1- Numbers, Number Systems and Number Relationships

(Equivalent forms)

2.2- Computation and Estimation

(Basic Functions, Reasonable Answers, Calculators)

2.6- Statistics and Data Analysis

(Collecting and reporting data, Analysis data)

Task

Objectives/Goals

  • You will be assigned a specific role:
  • Researcher (2),
  • Data collector, or
  • Recorder/presenter
  • You will plan the pizza party by gathering data and analyzingyour results.
  • You must come to a consensus with your group members about final plans for your party.
  • You will present your data in a variety of equivalent forms (fractions, decimals, percents).
  • You will organize your data using visuals (graphs, charts, etc.).
  • You will present your findings at the end of this project using a poster board or a computer presentation.

Focus Questions

  • When should the party take place?
  • Where should we hold the pizza party?
  • Should we get parental consent/involvement?
  • How many slices will each child eat?
  • What should we do if someone doesn’t like pizza or has an allergy to it?
  • Do we want entertainment, and if so, what kind of entertainment do we want?
  • What supplies will we need for our party (pizza, entertainment, utensils, etc.)? How many of each of these supplies should be ordered?
  • What percentages should be allotted for each of your supplies?
  • What are the corresponding fraction and decimal equivalents? (Document in a table)
  • Where will the pizza, snacks, utensils, etc. be purchased?
  • What stores, shops, etc. will give me the most for my money? (Document all findings in a chart).
  • Print out all circulars and/or coupons to verify actual sales.
  • How far in advance should the supplies be ordered?
  • When should the supplies be delivered? (How far in advance?)
  • How will we get these supplies? (Parents, siblings, friends?)
  • How can we best present our findings? (bar graphs, pie charts-no pun intended, pictographs, etc.)

Process

Getting Started

1)Make sure everyone in your group understands their role.

2)Make sure you understand the project, if there are any questions ASK ANYTIME!

Collecting Data

1)Create a chart. Plan your party for 25 students and don’t forget the teacher.

2)Conduct a survey of likes and dislikes (pizza, drinks, snacks and entertainment.)

3)Enter results of survey into chart.

4)Discuss with your group if this is the plan of action that you would like to take.

Data Analysis

1)Consider your chart and budget then begin researching websites of supermarkets, stores, and shops to purchase your food and supplies for your party.

2)Keep track of prices, values and availability found for each website researched.

Wrap Up

1)Discuss all findings with group.

2)Piece your project together.

3)Present your project.

Evaluation

For this assignment, you will be graded individually. The teacher will periodically check your notes and calculations, so No Copying or Cheating! Each group member will accumulate points in the following categories:

  1. Number Relationships (5pts)
  2. Computation (5pts)
  3. Data Collection/Analysis (5pts)
  4. Team Work (5pts)
  5. Craftsmanship (5pts)

The total number of possible points is listed next to each category. The entire assignment is worth 25 points. This assignment takes the place of 1 major test this marking period. The number of points you accumulate will be determined using the following rubrics:

1. Number Relationships

Points given / Explanation of score
5 / Student demonstrates the ability to express numbers as fractions, decimals and percents with no error.
4 / Student demonstrates the ability to express numbers as fractions, decimals and percents with few errors (1-2 errors)
3 / Student demonstrates the ability to express numbers as fractions, decimals and percents with some errors (3-5 errors)
2 / Student demonstrates the ability to express numbers as fractions, decimals and percents with multiple errors (6-9 errors)
1 / Student fails to demonstrate the ability to express numbers as fractions, decimals and percents (10 or more errors)
0 / Student fails to turn in assigned work

2. Computation

Points given / Explanation of score
5 / Student computes answer with no errors with all work shown.
4 / Student computes answer with few errors (1-5 errors) with all work shown
3 / Student computes answer with few errors (1-5 errors) with work missing
2 / Student computes answer with multiple errors (6 or more errors) with all work shown
1 / Student computes answer with multiple errors (6 or more errors) with work missing
0 / Student fails to turn in assigned work

3. Data Collection/Analysis

Points given / Explanation of score
5 / Student collects and organizes information with no error then presents the information using a type of chart
4 / Student collects and organizes information with few errors (1-5 errors) then presents the information using a type of chart
3 / Student collects and organizes information with many errors (more than 6 errors) then presents the information with the use a type of chart
2 / Student collects and organizes information with few errors (1-5 errors) without using a chart
1 / Student collects and organizes information with many errors (more than 6 errors) without using chart
0 / Student fails to turn in assigned work

4. Team Work

Points given / Explanation of score
5 / Student works well with group and completes task on time
4 / Student works well with group and completes task late
3 / Student works poorly with group and completes task on time
2 / Student works poorly with group and completes task late
1 / Students works poorly with group and fails to complete task
0 / Student is removed from group activity

5. Craftsmanship

Points given / Explanation of score
5 / Student goes above and beyond all requirements neatly and creativelyusing computer software
4 / Student meets all requirements neatly and uses graphics
3 / Student meets most requirements neatly and uses graphics
2 / Student meets most requirements neatly without using graphics
