Students have been learning about Greatest Common Factors, Least Common Multiples, and exponents. We started with a review of what students had learned last year about GCF and LCM. Next, students were introduced to a new way of finding the GCF and LCM of 2 numbers, and also learned how to find the GCF and LCM of more than 2 numbers. Students were then introduced to monomials. They used their knowledge of finding the GCF and LCM of numbers to find the GCF and LCM of monomials. Next, students helped establish rules for multiplying and dividing powers, as well as determine what negative exponents are. Students were then able to put together all that they had learned in this unit to simplify fractions that have monomials as their numerators and denominators.
