Title: Percent, Ratio, Proportion, Rate and Food Groups

Topic: Math Product: Functions Process: Reasoning

Science Product: Food Groups Process: Classifying

Student Level: 7th grade

Objectives: Academic: The students will demonstrate their knowledge of percent, ratio, proportion, and rate in conjunction with the food groups by solving their given word problems and explaining their reasoning to their answer.

Social: The students will demonstrate proper group skills by assigning job responsibilities to each person in their experimental group.

One person talking at a time / Each person working on a task

People quietly working / Group members working

On their task at hand / individually but towards a goal.

Materials: food cut-outs from the food groups, poster of the food pyramid, T-chart, and worksheet.

Prerequisite Skills: Knowledge of the food groups; Usage of the mathematical concepts of percent, ratio, proportion, and rate.

Time Required: 25 minutes.

Group Size: 5 students

Roles: All students to categorize food into food groups.

Introduction: 1. Morning Stretch

1. Questioning: Who can tell me what percentage means?

Who can tell me what rate means? Let's say Kyle shaves his go-tee once every two weeks. What is his rate of shaving per month? How about every week?

( 2 & 24)

Who can tell me what ratio means? Let's say Tina has improved her tardiness and is only late for class once a week. What is her ratio of being on time for class to the amount of days she is in class per week? ( For every three days she is late once).

Who can tell me what proportion means? Let's say Megan scores 10 points and gets called for 4 fouls per game. How many points and fouls would Megan have in 5 games? (50 & 20).

Development: Review food pyramid. Question students to the importance of eating healthy and how certain foods affect our energy levels and growth.

Divide students into groups of five.

Show T-chart of job responsibilities.

Explain to the students that they are going to be given rate, ratio, proportion, and percent word problems. They are to answer using assorted food cut-outs.

Explain to the groups their individual job roles.

Pass out assorted food cut-outs.

Pass out rate, ratio, proportion, and percent word problems to the students.

After students have been given time to answer their problems have each group state a word problem, answer, and how they came to their conclusion.

Positive Interdependece: Each student will successfully complete their assigned task in order for the group's outcome to succeed.

Individual Accountability: Each individual will have an assigned task that they must complete.

Criteria for Success: Students will verbally give their answer and give an explanation for their outcome.

Expected Behaviors: Students must successfully complete each job responsibility they are assigned in a cooperative fashion.

Monitoring: Observation of cooperation in groups. Give help when needed.

Processing: Ask each group on a scale of 1-10 if they feel that they worked well together and that everybody performed their assigned roles.

Conclusion: Discuss how being able to figure out the rate, proportion, ratio, and percentage can help us in our daily lives. Discuss importance of a healthy diet.

Evaluation: Teacher observation of cooperative groups. Each group must answer the four questions given on the worksheet. Each group must have two presenters, each stating their question, answer, and their reasoning behind it.

Extension: Give students the rate, ratio, proportion, or percentage of something and have them come up with their own word problems using the information.
