Measurement and Geometry combined unit: the wonderful world of CIRCLES!!!!

Hello all,

Your child and I will be exploring circles in the month of January. It is suggested that students bring in their own calculator with the pi function built in as well as a compass for drawing circles.  The curriculum expectations explored will be as follows:

Measurement

  • measure the circumference, radius, and diameter of circular objects, using concrete materials
  • determine, through investigation using a variety of tools (e.g., cans and string, dynamic geometry software) and strategies, the relationships for calculating the circumference and the area of a circle, and generalize to develop the formulas 
  • solve problems involving the estimation and calculation of the circumference and the area of a circle;

  • Geometry
    • construct a circle, given its centre and radius, or its centre and a point on the circle, or three points on the circle;
    • investigate and describe applications of geometric properties (e.g., properties of circles) in the real world.
