Lab Description

Welcome to the "Cookies Inc. - Recipe Ratios" Business Lab! This lab is designed to provide high school students with hands-on experience in entrepreneurship, mathematics, and business management.

In this lab, students will embark on a journey to start their own cookie business using grandma's special recipe. However, there's a twist – they begin with limited funds and must navigate through mathematical calculations, budgeting, and decision-making to turn their business idea into a profitable venture.

The lab unfolds in several stages:

  1. Business Idea Exploration: Students explore the concept of starting a cookie business, initially outside a mall using a cookie cart.
  2. Mathematical Conversions: Students apply mathematical concepts such as ratios and proportions to convert kitchen units (like cups and tablespoons) into standard units (such as pounds and gallons) for ingredients.
  3. Cost Calculations: Using a supplier's rate card, students calculate the total cost of making one cookie and determine the cost for a batch of 25 cookies.
  4. Budgeting and Purchasing: With a $1500 investment from grandma, students budget and purchase ingredients for their initial batch of cookies while ensuring they stay within budget.
  5. Sales and Revenue: Students track their sales at $1.20 per cookie, using the revenue from the first month to reinvest in ingredients for subsequent batches.
  6. Profit Generation: The ultimate goal is for students to generate enough profit by the end of the third month to repay grandma's initial investment and have an additional $3000 in profit.

Through this immersive lab, students will develop critical skills in mathematics, financial literacy, problem-solving, and entrepreneurial thinking. It's a dynamic learning experience that bridges the gap between classroom learning and real-world application, preparing students for future success in business and beyond.

Business Planning (18 Minutes)

Students will read and understand that they have to convert the ingredients from kitchen units (cups and tablespoons) to standard units (pounds and gallons) before preparing the purchase order.

Students will use basic math to convert the units using the given conversion table -

Students will read and understand that the ingredients given are for preparing 25 cookies, but to start the business, it is important to know the cost of one cookie. They will use the rate card provided by the supplier to calculate the total cost of a cookie.

Students will utilize the rate card provided and the quantities of ingredients calculated in the previous step to determine the total cost of producing a single cookie.

Month 1 of Business (28 Minutes)

The first step in the Month 1 activities is to plan the number of cookies to be produced. Students will do simple calculations to decide the number of cookies to produce for Month 1.

Here is a sample filled worksheet -

Students will read and understand how to place the purchase order, they will understand that they are buying ingredients from a wholesale supplier and their task is to find the number of bags of each ingredients to buy.

Students will utilize a purchase order form to determine the number of bags of each ingredient to be purchased. The challenge lies in the fact that students must order bags of each ingredient, not exact quantities, potentially leading to overbuying or underbuying to match the available budget.

Common Core: MATH

Expressions & Equations

Write, read, and evaluate expressions in which letters stand for numbers.

Number System

Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. *For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) ÷ (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?*.

Ratios & Proportions

Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. *For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak." "For every vote candidate A received, candidate C received nearly three votes."*

Ratios & Proportions

Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. *For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger."*

Ratios & Proportions

Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

Ratios & Proportions

Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.

Ratios & Proportions

Solve unit rate problems including those involving unit pricing and constant speed. *For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?*

Ratios & Proportions

Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. *For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction ^1/2/1/4 miles per hour, equivalently 2 miles per hour*.

Ratios & Proportions

Recognize and represent proportional relationships between quantities.
