5:05Decimal cards

Decimal cards are set out in three columns; the first with numbers to one decimal place, the second with numbers to two decimal places and the third with numbers to three decimal places eg. 0.1, 0.01 and 0.001. These cards could be superimposed on each other to make other decimal numbers eg. 0.11 or 0.111. Decimal numbers are recorded in the pattern with cards for numbers from 0.0, 0.00, 0.000 to 0.4, 0.04, 0.004.
