Unit 8: (X, Y ) Marks the Spot!



  • This unit focuses on calculating the perimeter and area of two-dimensional figures and the perimeter, area, and volume of three-dimensional figures.
  • Many two-dimensional geometric shapes can be defined by a set of points or vertices and lines connecting the points in a closed chain, as well as the resulting interior points. Such shapes are called polygons and include triangles, squares, and pentagons.


  • Use concrete and graphic models to derive formulas for finding perimeter, area, surface area, circumference, and volume of two- and three-dimensional shapes, including rectangular solids, cylinders, cones, and pyramids.

Algebraic Thinking

  • Determine the impact when changing the parameters of given functions.
