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.
Are there too many problems on the page? Some authors attempt to pack in the problems, leaving little room for students to show their work. The opposite can also be the case. Maybe there are not enough problems to accurately assess student knowledge. Are the digits on the printed page large or small? In my opinion and within reason, the numbers can never be too large. Exhibiting stress at an early age on elementary studentsí eyes from staring at small print can lead to stronger prescription lenses.
