Computer Decimal Comparison Test
The Decimal Games begin with the Decimal Comparison Test. Its purpose is to automatically diagnose how students are thinking about decimal notation. The student is asked simply to choose the larger decimal number from pairs of decimals, or to say if the decimal numbers are equal.
The computerised Decimal Comparison Test is marked automatically and the results are fed into the various games within the Decimal Games system, so that the games provide the students with tasks that reveal their individual misconceptions.
This computer version of the Decimal Comparison Test has a wider variety of items than that in the Test Section of this resource, so it provides a more thorough diagnosis. It is best if students complete all the items, but if they do not, the system makes a judgement based on whatever information is available.
