At this level of the journey into mathematics, students are often writing expressions to solve problems. Many students, however, do not believe that this math applies to their daily lives. The activity Rewriting Expressions when Problem Solving is packed with familiar real world situations that allow students to write expressions in different forms and helps them to see different approaches to problem solving, as they deal with discounts, taxes, restaurant tips, trips to the movies, and more.
By writing expressions in different ways, students get a good sense of the relationships between the quantities, and are able to use different approaches to finding solutions. Students will understand different ways to approach these familiar real world problems, and understand that they can be solved by looking at the problem in different ways. This activity may just make that trip to the mall or restaurant a bit more interesting!
