Week #March 29-April 2
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-CO.1.3:  Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.

MAFS.912.G-CO.4.13:  Construct an equilateral triangle, a square, and a regular hexagon inscribed in a circle.

MAFS.912.G-CO.1.5: Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another.

Learning Targets and Learning Criteria
  • 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.
  • decompose more complex figures whose vertices are given using coordinates into familiar shapes that are easier to work with.
  • describe and illustrate how a rectangle, parallelogram, and trapezoid are mapped onto themselves using transformations.
  • calculate the number of lines of reflection symmetry and the degree of rotational symmetry of any regular polygon.
  • define inscribed polygons.
  • construct an equilateral triangle, a square, a hexagon inscribed in a circle.
  • explain the steps to constructing and equilateral triangle, a square, and a regular hexagon inscribed in a circle.
  • draw a specific transformation when given a geometric figure and a rotation, reflection, or translation.
  • predict and verify the sequence of transformations (a composition) that will map a figure onto another.
Classroom Activities


  1. Students will log onto the Zoom session.
  2. We will use the Math Open Reference website to learn how to construct a square, triangle, and hexagon inscribed in a circle.
  3. We will go to the Geogebra website and explore rotational symmetry and line symmetry,
  4. Students will do IXL L.11.
  5. We will review transformations and do a few problems on mapping a figure onto another one.
  6. We will do some notes and practice on finding the area and perimeter on the coordinate plane.
  7. Students will do IXL S.6.


  1. There are no Zoom sessions today.  Face to face students will participate in the Rainforest FSA/EOC Review Day!


  1. Students will log onto the Zoom session.
  2. Students will take notes on Population Density and do a few examples.
  3. We will learn how to find the area of compound figures and will do some practice problems together.
  4. We will do a few problems on Compound figures from the workbook (p. 167).
  5. We will do Quizlet Live to review properties of Quadrilaterals.
