In this performance task, students create their own word problems that can be solved using a linear equation (y = mx + b). The task contains step-by-step components and an example for each step, prompting students to...
(1) Identify two quantities that varies linearly and predict a logical relationship between them as increasing, decreasing, or constant.
(2) Create a rate of change (slope) and initial value (y-intercept).
(3) Model the scenario with a linear function in y = mx + b form.
(4) Create a question that gives a value for either x or y and requires solving for the other variable.
A handout is included for students to write their finalized word problems, at which point they switch with a classmate and attempt to write the equation and use it to solve the question. The partner is then prompted to interpret the meaning of the slope and y-intercept in context of the scenario.
- Includes a Common-Core Standards based rubric of 5 components, with room to write areas of strength and suggestions for improvement.
- Includes a Task Card for posting as a bulletin board assignment.
- Includes an idea handout for quantities that can be modeled by a linear relationship (differentiation for ELLs or SWDs).
- Includes a formal lesson plan, with teaching point, questions, vocabulary, etc.
