Consider an assessment you could use in your professional context. For this assignment, I would like to revise a portfolio assignment that is used as part of the curriculum in Math 6 courses. The instructions on this portfolio can be confusing for students, and I often receive questions from students about what to do for this portfolio and how to complete it. I would like to revise this portfolio in order to make it easier for students to understand while still assessing them on the concepts discussed below.
Identify the purpose of your assessment. There are a couple of objectives for this assignment. First, it will assess whether students are able to calculate the area of a circle given the length of the diameter, and if students are able to calculate the area of rectangles and squares. Students will have to use critical thinking in order to create dimensions for a rectangle or square so that it has an area that meets the requirements of this assignment. Students ability to divide will also be assessed in this portfolio. This portfolio will be assigned to students during the review lesson before the Unit Test on Geometry and Measurement.
Name and describe the assessment you have in mind. This portfolio will be called "Create a Pizza Portfolio". Students will be given an example of a circular pizza with its dimensions that is sold at a pizza store, and also the dimensions of the box that it fits in. Students will have to create their own pizza that is a different shape, and show that it is approximately the same area as the given circular pizza, show that it will fit in the given box, and lastly show that it can be cut into 8-12 equal-sized pieces. This assessment will give students the opportunity be apply their skills to a real world situation to encourage higher order thinking.
Write instructions for this assessment. Below are the instructions I have created for students for this assignment. They may change as I continue to build and create this portfolio.
Directions: A large pizza at Tony's Pizzeria is a circle with a 14-inch diameter. Its box is a rectangular prism that is 14 1/8 inches long, 14 1/8 inches wide, and 1 3/4 inches tall. Your job is to design a new shape for a large pizza. For this portfolio you will:
1) Create a representation of your design that includes measurements.
2) Prove mathematically, using appropriate formulas, that your design is approximately the same area as Tony's large pizza.
3) Show that your pizza will fit in the box.
4) Prove that your pizza can be cut into 8-12 equal-sized pieces.
