There are many opportunities to teach your child how to count. You probably already have books with numbers and pictures, and you can count things with your child all the time. There are counting games and blocks with numbers on them, wall charts and a wide variety of tools to help you teach your child the basic principles of math. Mathematics worksheets can help you take that initial learning further to introduce the basic principles of math to your child, at a stage in their lives where they are eager to learn and able to absorb new information quickly and easily.
There are many good workbooks available for kindergarten children. However with a regular workbook, a child can do each activity or worksheet only once. A good option is to use printable kindergarten worksheets. These are basically digital versions (like ebooks) of worksheets that can be bought and downloaded to your computer from the internet or from CDs and then printed out. The advantage is that you can print out whichever sheet you wish. If you need to re-inforce a certain concept more you can usually print out that sheet again. Of course you will therefore need to have a computer and a printer.
From a teachers perspective our competition is tough. Passing out a handout of 30 problems that are all in a format of 534x25= is not as stimulating in the students eyes as playing games such as Grand Theft Auto and Resident Evil. Granted, that will always be a tough uphill battle for math to win out over most video games, but the point is, students today are much more immersed in technology than ever before. So even if you need to pass out a math worksheet to review concepts and formulas, it will greatly benefit your cause if you design the worksheet to be as stimulating as possible.
