This Instructional Activity is a part of the Lesson 17, Unit 1, Grade 6. This activity introduces students to the exponents of 2 and 3 and the language we use to talk about them. Students use and interpret this notation in the context of geometric squares and their areas, and geometric cubes and their volumes. Students are likely to have seen exponent notation for 10^3 in their work on place values in grade 5. That experience would be helpful but is not necessary. Note that the term "exponent" is deliberately not defined more generally at this time.
