This lesson unit is intended to assess students’ understanding of the four quadrants of the coordinate plane, while at the same time introducing them to a mathematical understanding of slope. The task helps students to link their intuitive understandings of steepness to a more precise,...

This unit, Go Figure!, focuses on the geometric concepts of perimeter, area, surface area and volume. Students begin by working on the coordinate plane to find the perimeter and area of rectangles. The formula for the area of a rectangle is then built upon to create a formula for the area of...

## Theme Park

CertifiedStudents will work independently to design a theme park and determine a variety of measurements using both algebra and geometric skills.

They will construct viable arguments concerning their design of a theme park and model with mathematics while using appropriate tools strategically....

In this task students will design and analyze an object made of regular shapes of their choosing. They will specifically analyze how changing the object's dimensions based on a set of self-created equations affects the properties of that object. They will then produce a poster to display their...

## Dog’s Play Area

CertifiedIn this task, students respond to a geometry problem in which a girl is attempting to find the optimal location to tether her dog so that the dog doesn't dig in the garden, but without reducing the play area for the animal.

Students are given a number of measurements and constraints and...
