This document provides an overview of a lesson on writing division expressions without using the division symbol. It includes examples of writing expressions for 1 divided by 2, a divided by 2, and expressions involving variables. Students are given exercises to write expressions using the division symbol and as fractions, such as 12 divided by 4 and the quotient of 6 and m. The lesson teaches that division expressions can be written as fractions by making the dividend the numerator and divisor the denominator.
