Storyline: The local community has decided to come together to organize a special Thanksgiving feast for everyone to enjoy. The student volunteered to take charge of the event and turn it into a memorable community gathering. The student is given $1000 as initial funds to purchase all the ingredients needed for a delicious Thanksgiving meal.
Each meal will include the following items:
The student's task is to find out how many meals can be prepared using the $1000 initial fund. To do so, students will first convert the measurement units of each ingredient from cups/tablespoons and ounces to pounds and gallons. Then they will use the given rate card to calculate the cost of each ingredient and finally, they will calculate the total cost of a meal.
The learning objectives are:
Common Core: MATH
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."*
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.
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?*
