Netflix vs. BingeNow – Write & Evaluate Expressions
In this engaging real-world activity, students explore how algebraic expressions can help them make informed financial decisions. Presented with three different streaming subscription options, students will:
- Write expressions to represent total costs using variables (e.g.,
12x + 20) - Evaluate those expressions for different values of
x(months) - Compare and interpret the results to identify the most affordable plan
- Set two expressions equal to determine break-even points
- Justify their decision based on their evaluations
This worksheet helps students strengthen their understanding of expressions, variables, constants, and coefficients, and see how math applies in everyday decision-making.
Interactive twist: If randomization is enabled, each student receives a unique set of subscription values, ensuring individualized learning and minimizing answer sharing.
Learning Objective
Students will write, simplify, and evaluate algebraic expressions to model real-world subscription costs over time. They will use variables to represent time, analyze how setup fees and monthly charges affect total cost, and apply reasoning to compare different pricing models. By the end of the activity, students will be able to make informed decisions by interpreting and using expressions in meaningful financial contexts.
Randomization Prompt
If randomization is enabled, each student will receive different pricing details for the streaming plans—such as setup fees and monthly rates. This ensures that:
- Each student generates and evaluates unique expressions
- Answers are individualized, discouraging copying
- Students must rely on their own reasoning to compare and choose the best plan
This approach supports differentiated learning while reinforcing the real-world application of expressions.
