Action on Angles

Angle, from Chalksoft, is a package of four programs which go together in pairs - a demonstration program and a program where the new know ledge is put into practice.

The first demonstration program measures angles as fractions of a turn, relates these fractions to degrees and then estimates angles in terms of degrees.

The second demonstration program shows how to use an angle indicator (a protractor to measure 360 degrees).

Angles are drawn and the angle indicator superimposed. The angle is then read off the scale. Both programs are clear and helpful, the second particularly so.

Each contain sufficient exam ples to put the points across clearly.

The interactive programs use the knowledge learned from the previous program and there were no ambiguous questions. Unfortunately there is no help if the wrong answer is given.'

This package is most useful in the classroom. The development of the content is well thought out and works well in practice.

The use of graphics is excellent throughout.
