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.
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.
