This resource contains a number of activities and investigations designed to use basic geometrical properties of shapes to investigate the situations presented or solve the problems posed. Some of the tasks may appear a little dated but the ideas are valid and can be used for inspiration when lesson planning.
Task 7, Symmetry, presents three shapes made from squares and asks students to make as many different symmetrical shapes as they can. This task can be followed by Task 8, Polyominoes, in which students are asked to make as many triominoes, tetrominoes and pentominoes as possible.
Task 14, Triangles, presents a 3 by 3 pin board and requires students to make as many different triangles as possible. Task 18, Roofs explores how to draw quadrilateral shaped roofs on isometric paper.
Task 21, Crooked stars, asks students to investigate tessellating shapes. Task 25 Squares symmetry requires students to investigate how many different symmetrical patterns can be found. Task 28, Triangulating, asks students to investigate how many triangles can be formed when diagonals of larger shapes are drawn.
Task 32 explores the similarities involved in international paper sizes. Task 35 requires students to solve problems based upon tetrominoes.
