In this lesson, students are introduced to rate in the context of music. They will explore beats per minute and compare rates using mathematical representations including graphs and double number lines.Key ConceptsBeats per minute is a rate. Musicians often count the number of beats per measure to determine the tempo of a song. A fast tempo produces music that seems to be racing, whereas a slow tempo results in music that is more relaxing. When graphed, sets with more beats per minute have smaller intervals on the double number line and steeper lines on the graph.Goals and Learning ObjectivesInvestigate rate in music.Find beats per minute by counting beats in music.Represent beats per minute on a double number line and a graph.

In this lesson, students explore rate in the context of grocery shopping. Students use the unit price, or price per egg, to find the price of any number of eggs.Key ConceptsA unit price is a rate. The unit price tells the price of one unit of something (for example, one pound of cheese, one quart of milk, one box of paper clips, one package of cereal, and so on).The unit price can be found by dividing the price in dollars by the number of units.The unit price can be used to find the price of any quantity of something by multiplying the unit price by the quantity.Goals and Learning ObjectivesInvestigate rate as a unit price.Find a unit price by dividing the price in dollars by the number of units.Find the price of any quantity of something by multiplying that quantity by the unit price.

Prices send signals and provide incentives for buyers and sellers in ways you possibly never thought about. In a market economy, price signals prevent massive shortages and ensure that consumer wants are largely satisfied. In this podcast, hear how price signals from gas prices influence decision-making for both a father of three and a production supervisor for an oil refinery. Do you see price signals influencing decisions in your life?

What exactly is a carbon price, and how does it work? What would it look like and how would it change everyday life? In this episode of TILclimate (Today I Learned: Climate), MIT economics professor Christopher Knittel joins host Laur Hesse Fisher to break down the complexities of carbon pricing. Together, they explain different types of programs, give us a sense of how much it would cost, and explore how countries and U.S. states are experimenting with carbon pricing now.

Students will navigate a Spanish supermarket website looking for different items in various departments. Students will also talk about foods, beverages, and restaurants. Students will express their likes and dislikes in regards to foods, beverages, and restaurants.

In this activity, students will go shopping at different grocery stores in search of the best prices for their foods. Students will use vocabulary involving food, money, and numbers. They will also learn about culture through the use of discussing grocery stores. Students will also learn how to ask and answer questions about shopping and selling. 

This seminar will prep you for the real shopping experience.  Be able to ask how much something costs and how to describe the price- is is expensive or cheap? You will be able to use adjective and clothing vocabulary to be specific in what you are asking about too!ACTFL StandardsCommunication: Interpersonal CommunicationConnections: Making ConnectionsLearning TargetI can understand a simple transaction between a customer and a sales clerk.Habits of MindStriving for accuracyCritical Thinking SkillComparing
