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.
Linking by creating a formula. With this method you can create an inter_active link between worksheets or workbooks. The linked cells do not need to be in the same location on all worksheets. You can perform any math operation while creating the link. For example, you could take a figure from one worksheet, multiply it times a figure form another worksheet and then subtract a number from a third worksheet. You can use this method to link cells across worksheets or workbooks. One disadvantage of this method is that it is time consuming because you are working with one cell at a time. Using named ranges can assist with this method of linking and make it easier to read your formulas once they are created.
