Algebra: Writing equation for perimeter
Activity Description
This worksheet helps students to write their own algebraic equations to solve a real-world problem.
Storyline:
Students got a new job in a painting company where their job is to estimate the paint needed for painting the wall baseboards, door trims, and door areas. The calculations were done manually, but the student is asked to automate this process by finding formulas that can automatically compute the paint needed when the dimensions of the room, doors, and windows are given.
Students will try to understand the relationship between different variables such as width, height, perimeter etc.. and write the formula to find the area of a room using these variables. They also are given the opportunity to validate their formula by running test cases against the formula. In the same way, they will write formulas to find the door trim area and door areas.
This is a good algebra refresher activity and at the same time, it is thought-provoking to create fresh formulas.
Learning Objective
Students use this activity to understand a problem and then to form an equation that can solve the problem. Students can validate if their equation is correct by running the test cases.
