This document includes a real world situation to help students understand the concept of variables, coefficients, constants, and algebraic expressions, along with practice problems. It is important to stress the fact that there is no name of the restaurant on the menu provided, meaning that the prices of the food items can VARY depending on the restaurant itself and/or the day. Next, there are guided notes on the formal definitions of each of these terms, along with guided practice. Finally, this document contains an activity for students to complete in pairs (or groups of 3) to consolidate their knowledge of these ideas. The idea is to have students complete the activity, then hang the final products around the room, and have the students complete a "gallery walk."
