Big Idea: An algorithm can be an effective and efficient way to multiply decimals. This lesson builds on students' experiences in fifth grade with visual and other conceptual models associated with multiplication of decimals. The purpose of this standard is to have sixth graders understand and fluently use the multiplication algorithm to solve problems with decimals. This builds towards multiplying rational numbers in 7th grade. Successful use of the standard algorithm is the goal of this lesson. However, conceptual models should be used to make connections to the algorithm and lead to students successfully multiplying decimals with the standard algorithm. In this task, students are asked to make an ice cream creation at Sweet Treat Ice Cream Parlor for a young girl named Jasmine. Students may use some addition of decimals as they build their own ice cream creations with ice cream and toppings. They will use multiplication of decimals to determine whether their ice cream creation will be less than $2.75 using the weight of their ice cream creation and the price per pound. Vocabulary: Factor Product Decimal Tenths place value Hundredths place value Thousandths place value Decimal point Special Materials: 1) Decimal place value charts (for adding decimals)
