Numerical Order

This program gives practice in arranging numbers in numerical order. The range of values and the order, ascending or descending, are selected by the user. The instructions are displayed on the screen and optionally heard.

Ten randomly generated numbers in the selected range are displayed in yellow circles. When the user clicks on a yellow circle in the correct order, it disappears and is replaced by a green circle at the top of the screen. When an incorrect number is selected, its circle momentarily turns red and then returns to yellow. A point is scored for every correct number selected and a point is deducted for every incorrect number.

When all the numbers have been selected, the score is divided by two and a success rating of up to 5 stars is displayed and the user is invited to try again. The success rating is not displayed if the user has less than two points.
