Look for patterns when powers of 10 are divided. Let's explore patterns with exponents when we divide powers of 10. Learning targets: students can explain and use a rule for dividing powers of 10. Students investigate fractions that are equal to 1. This is an important concept that helps students make sense of the exponent division rule explored later in this lesson. It is expected that students will try to compute the numerator and denominator of the fraction directly in the first problem.
