Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: A penny is about $\frac{1}{16}$ of an inch thick. In 2011 there were approximately 5 billion pennies minted. If all of these pennies were placed in a s...

For this task, students use various approaches to solve a multi-step percentage problem.

In this task, students write an expression for the perimeter of a rectangle and use the expression to find the perimeter of a rectangle with a given length and width.

In this task, students determine the correct expression and how students may have been thinking when determining the perimeter of the rectangle.

This unit is loaded with phenomena. The real world task of being a member of Oregon's Energy Commission that must create a 50-Year Energy Plan propels students through a learning arc that includes electricity, magnetism, power production, and climate science. After the Request for a 50-Year Energy Plan students jigsaw energy sources and power production. They need to understand the basic physics of how generators works leads us to build and explore motors (starting with speakers which also connect to the Waves & Technology unit) and inefficient generators (electric guitars). The need for large amounts of energy and efficient generators motivates us to engineer wind turbines and optimize solar cells for a local facilities use. Creating the rubric to evaluate large scale power production launches us into climate science. With all the learning of the unit students and many real world constraints student finally complete, compare, and evaluate their 50-Year Energy Plan.

In this assessment, students draw polygons on a coordinate plane and solve real world problems with polygons on a coordinate plane.

In this assessment, students use coordinates and side length to find the last coordinate of a rectangle.

This task helps illustrate Mathematical Practice Standard 4 and engages students in
grappling with aspects of the problem to determine how to use mathematics to solve
it. Students must apply multiple mathematics standards in this real life problem
situation and discuss what needs to be painted, how the area should be calculated, and
how many cans of paint are necessary.
