Circle Measurement

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of circle measurement, plus two other related resources.

Circle measurement pack one contains nine work cards with a wide variety of activities covering finding the length of a running track and the circumference of a circle, naming different parts of a circle, and calculating the area of a circle.

Circle measurement pack two contains ten work cards with activities requiring students to investigate packing circles into a square, find the area of a sector of a circle, find approximations to pi, and find the area of non-uniform shapes.

Straight lines, SMILE card 1679A explores lines and regions formed on a sphere, calculating the length of a line on a sphere, and explores longitude and latitude as a method of fixing positions on a sphere.

Triangles, SMILE card 1679B explores how to make triangles on a sphere, how to measure the triangles on a sphere, nine statements about triangles, and how to calculate areas and angles of triangles formed on a sphere.

SMILE card 1679E is required when using the Triangles resource.

SMILE (Secondary Mathematics Individualised Learning Experiment) was initially developed as a series of practical activities for secondary school students by practising teachers in the 1970s. It became a complete individualised scheme based around a network of activity cards and assessments. Related resources include answers to all of the cards and test books and answers.
