Developers of free math worksheets primarily use either of two methods for displaying and printing worksheets on the Internet. PDF pages require an additional piece of software, Adobe Acrobat, which should automatically open worksheets in your browser. PDF worksheets theoretically cannot be manipulated and display/print precisely as the developer designed. The second mode of delivery, HTML code, displays worksheets directly in your browser window. The downside of using HTML based worksheets is they are prone to printing problems. A worksheet meant for one page can easily bleed over to a second sheet.
Whereís the answer sheet? Are the answers correct? Are the answers listed in a column that you have to match with the student worksheets or on a replica of the student page laced with answers? Last thing you need is to be in a hurry and red mark student worksheets...when their answers were correct all along.
