This Instructional Activity is a part of the Lesson 5, Unit 5, Grade 6. In this activity, students continue to think about products of decimals using fractions. They use what they know about 1/10 and 1/100, as well as the commutative and associative properties, to identify and write multiplication expressions that could help them find the product of two decimals. While students may be able to start by calculating the value of each decimal product, the goal is for them to look for and use the structure of equivalent expressions, and later generalize the process to multiply any two decimals.
