    Calculate Average Food Cost

    Calculate Average Food Cost

    Overview

    In this lesson students will practice computing the average or mean of 3 or more menu prices or numbers with decimals.

    Lesson Plan


    Lesson Plan

    Grade Level: _6th_ Subject: _Math/Computer Science_ 

    Unit of Study: _Non Fiction / average / collect and organize data__ Unit:  _Road trip_ Lesson:  _1-2_

    Daily Lesson Objective:

     

    By the end of the lesson students will be able to determine the average or mean menu price for similar menu items across multiple restaurant menus with 90% accuracy.


     

    Virginia Standard(s) of Learning:

    Math

    6.5 The student will

    c)  solve multistep practical problems involving addition, subtraction, multiplication, and division of decimals.   

    Computer Science

    6.8 The student will use computational tools to collect, organize, and clean data to make it more useful and reliable. 

    Warm Up/Hook:      Time 3-5 minutes

     

    Time: 5 minutes

    Begin the lesson by continuing the conversation about restaurant food prices.  Discussing the need to have some idea of how much food will cost for the students road trip.  Talking about how menu items have different prices depending on the restaurant they choose to eat at.  Give the example: a small cheeseburger costs $4.49 at Burger King and $1.00 at McDonalds.  With such a variation in prices it would be a good idea to get an average cost of food items they think would be of interest to them while on their trip.


     

    Learning Plan/Activities:

    Time: 15 minutes

    Review the process of computing the average or mean or mean of the different menu prices by adding the menu prices and dividing the answer by the number of prices added.  Using the example from the warm-up the average cheeseburger price between Burger King and McDonalds would be:

    $4.49 + $1.00 = $5.49 2 = $2.75

     

    Discuss benefits in knowing the average or mean price of food in planning the budget for your trip.

     

    Activity/Practice (Student Actions):

    Time:  30 - 45 minutes

    Teacher Instructs the student to navigate to the menu with the price website.  The teacher should pick a menu item and demonstrate on the website how to find the menu item in multiple restaurant menus. Picking a common menu item will make it easier to find across multiple menus. 

     

    The teacher will display a sample page from a digital journal entry that will demonstrate how students should organize their information about the average or mean price of menu items.  

     

    The student will work independently or in a small group to review the auto brochures and record in their digital journal the average menu price for at least 3 breakfast items, 3 lunch items, and 3 dinner items.
