Decimals tests a pupil's understanding of place-value series and the multiplication and division of decimal fractions by ten and 100. A question might ask, for example, 'what is 3.7 x 100?'. If the child gets it wrong a help window appears and the process is taught clearly and graphically, using the example in which the mistake was made. This very useful little program can be used to reinforce understanding of decimal fractions and place-value series.

Keyboard play: very good
Graphics: clear graphical representations in the help window, attractive colour
