Q3, W7: Geometry (February 18-22)

TeacherKristin Andreason
Subject AreaGeometry
Grade Level8
Week #Seven
Unit of InstructionUnit 6: Two-Dimensional Measurements
Standard(s) Taught

MAFS.912.G-GPE.2.7:  Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula.

MAFS.912.G-MG.1.1:  Use geometric shapes, their measures, and their properties to describe objects.

Learning Targets and Learning Criteria
  • Students will use the distance formula to compute the perimeter and area given the coordinates of vertices of a polygon like triangle, square, rectangle, kite, rhombus, trapezoid, etc.
  • Students will be able to decompose more complex figures whose vertices are given using coordinates into familiar shapes that are easier to work with.
  • Students will be able to represent real-world objects as geometric figures.
  • Students will estimate measures of real-world objects using comparable geometric shapes.
  • Students will find the area of a figure using nets.
Classroom Activities


  • Students will finish the packet on Area of Composite Figures.
  • Students will do IXL S.10


  • Students will continue working on IXL S.10


  • Second period students will take the DIA on Thursday.
  • 5th and 8th period will do a Real-Life Area of Composit Figures packet and also an Area on the Coordinate Plane packet.
Assignments Due
  • IXL S.10 due on Wednesday, February 20.
  • Real-Life Area of Composite Figures packet due on Friday, February 22 or Tuesday, February 26.
