The object of this game is to make whole cookies using fractional pieces.

Press the <Start> button to display pieces of cookies. Use the mouse to drag the pieces onto the circle to make a complete cookie. When half or more of the cookie is made by dragging, a dialog (Cookie Making Machine) will slide on so that you may enter the exact remaining amount to complete the cookie.

When you run out of cookie pieces, the Cookie Making Machine dialog will let you enter the final amount to complete the cookie.

The timer starts after you drag the first piece onto the empty circle so it would be a good idea to plan your strategy before you start dragging. The timer stops when all the pieces are gone and the final cookie is complete.

After the cookie pieces are gone and the final cookie is complete, you may press the <New Pieces> button for more pieces. You may press the <Start> button to reset the minutes, seconds, and the number of cookies back to to 0.

The Cookies Per Minute score is the average number of times a complete cookie is made in one minute. Try to achieve a score of 3 or better. A score of 5 or more will make you a cookie builder expert.

By playing the Cookies for Grampy game you are learning addition, subtraction, and multiplication of fractions.

The <Report> button will open a dialog box that will ask for your first and last name . The <Send> key on the dialog box will open a browser window with your report card.

Have fun. Grampy loves cookies.
