If you print it out, it should format nicely with the problems on the first page and the answers on the second.

Be sure that you enable cookies, if you want to save your progress and keep track of which practice games you've finished and how long they took you. Parents and teachers- this is a great way to check your child's progress. Just click on "Show Scores" to see what games have been completed, how many problems were correct and how long it took to finish the worksheet. (Currently the program keeps track by computer. Soon we hope to add the ability to keep track of different players using the same computer.)
