How many Worksheets can I Create within one Workbook? _ Prior to the release of Excel 2007 users could only create 255 within one workbook. However, since the release of Excel 2007 users can now create as many worksheets within one workbook as the memory of the computer can handle. Even if the user does not have access to one of the newest versions of Excel such as Excel 2007 or Excel 2010, they can still make as many worksheets as they would like, but earlier versions of Excel will require more workbooks.
If the materials do not specifically indicate "brain_based," determine if they are at least "brain_friendly." This would mean that you are looking for lots of color, material interesting to the child, many varied activities_especially involving movement, and using several of the senses. I saw one company whose worksheets included the instruction to "say the number out loud as you..." This is very good! Speaking out loud is very important for learning to occur. Ideally, all worksheets should include this instruction. If you can't find any that do, then you need to add that instruction yourself. NEVER use "skill and drill" worksheets. These are the worksheets just made up of columns of problems. There are better materials out there, so don't resort to skill and drill. The very worst problem of skill and drill worksheets is the greatly increased chance of a practiced mistake. The same problem will likely appear several times on the same sheet. A wrong answer once means a wrong answer several times; and a practiced mistake takes hundreds of correct repetitions to fix. This danger alone is important enough to never use any worksheet. I am quite serious about how difficult it is to repair a practiced mistake. Learning is hard enough. Re_learning is much more difficult.
