2. Exploring Exponents How exponents change the value of numbers

3. Next Generation Standard NxG.M.8.EE.1: know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 3 2 × 3 –5 = 3 –3 = 1/3 3 = 1/27. (CCSS Math.8.EE.1)

4. Defining Success re-write numbers with exponents approximate the value of numbers that have exponents

5. Compare 3 3 and 3 2 27 9 Know what a negative exponent means 5 -2 0.25

6. Let’s Get Started! 4 3 4 4 5 3 = 125 5 -2 = 0.25
