Geometry Syllabus - Class 4 & 5

A. Participants engage in Triangle Investigations.

Participants should choose investigations that involve:

  • Classifying triangles according to their properties (e.g. acute, obtuse, right, isosceles, equilateral, equiangular, scalene)
  • Solving problems involving the area and perimeter of triangles
  • Making graphical representations of triangles and shapes composed of triangles
  • Using Pythogorean Theorem, right triangle rules (30-60-90, 45-45-90) and ratios for sine, cosine and tangent of angles to solve problems

Week 4: Choose from recommended investigations concerned with classifying and investigating a variety of triangles

Week 5: Choose from investigations focused on area, perimeter, and trigonometry with triangles

B. Participants add write-ups to their online portfolios

C. Introduction of the spreadsheet program
Triangle investigations using the spreadsheet program:
