The Detective Adjective Exercise is a unique exercise which combines language skills with geometric recognition.  The set consists of sixty-three plastic triangles (twenty-one each in yellow, blue and red) of different sizes and types.  Students sort the figures by colour, size and type (i.e. equilateral, isosceles, obtuse) and then describe them according to their attributes.  For example, “the small blue isosceles right-angled triangle”.  The set comes in a storage box with lid measuring 25 x 17 cm (about 10″ x 6.5″).

• 7 different types of triangles in 3 sizes and 3 colours
• 63 pieces total
• Triangles are thick, flexible plastic
