Lesson objective: Apply knowledge of using a given rule to create a pattern to a real-life problem.

This lesson provides an opportunity for students to apply their knowledge and understanding of patterns to a real-life situation. Students are asked to use a given rule to predict the number of liters of lemonade that will be sold in a lemonade stand, and to use that information to determine the number of lemonade packets that will need to be ordered.

Key Concept students will use:

• We can create patterns according to a rule, and find features of the pattern that are not explicit in the rule itself.

Skills students will use:

• patterns involve arithmetic (in the addition table or multiplication table), and can be explained using properties of operations. (Grade 3, Unit 8; 3.OA.D.9)

Students engage in Mathematical Practice 7 (look for and make use of structure) as they closely examine numbers to determine a pattern and think about the patterns seen in different operations. Students will begin to look for predictable ways that numbers may increase or decrease, such as looking for multiples. They will also begin to see commonalities between numbers in order to more easily decipher patterns and make conclusions on the features of patterns.

Key vocabulary:

• patterns
