This document outlines a lesson on writing algebraic expressions using letters to represent numbers. The lesson includes 6 practice stations where students write expressions for word problems involving letters for unknown values. They work through examples like "The sum of a and b" and "Martha bought d number of apples and then ate 6 of them." The document provides the expression answers for checking understanding. It then describes 2 rounds of timed practice sprints for students to complete before finishing with an exit ticket assessment. The goal is for students to learn to write expressions recording all operations on numbers and letters standing in for unknown values.

One "station" at a time, you will
write down the problem and the
expression with variables and
numbers.
Then we will review the answers
before moving on to the next
station card
