SMP 11-16 Angle Measurers Pack of 5 (School Mathematics Project 11-16)

The SMP Angle Measurers and Pie Chart Scales The SMP angle measurer has many advantages over the half-moon protractor, helping with the difficulties that arise (positioning of the zero line, understanding the scale to use, conceiving angle as turning). Each pack contains five angle measurers. Referred to in the SMP Interact books but suitable for use with any course.
