This Instructional Activity is a part of the Lesson 14, Unit 7, Grade 8. In this activity, students answer questions about quantities in context. They use scientific notation as a tool for working with small and large numbers-to describe quantities, make estimates, and make comparisons (e.g., to express how many times as much one is as the other). If possible, display an attention-grabbing image of cats and people for all to see. Ask students, "How many humans do you think there are for each cat in the world?" Ask for estimates that are too high, too low, and as reasonable as possible.
