A lot of the websites charge high dollar amount for these math worksheets. Considering your willingness to spend the high dollar, you run in to a new problem - the uniqueness of the material, a lot of websites offer sheets packed with identical problems leading the child to almost rote memorization of the problems and solution. This leads to deprivation of student and his/her ability to solve the problems logically. And some websites offer sheets in portable document format. And to open such sheets you are forced to download special software.
A systematic set of mathematics worksheets will help you teach your child the basic principles of math and help them prepare for school. Worksheets can be used as the basis for counting and adding games and other activities. Teaching your child with worksheets also makes them more comfortable with doing worksheets - which will help them when they get to kindergarten and school, where worksheets are used every day. You can make math interesting and meaningful for children with fun materials, games and activities. Math for preschoolers goes beyond counting. Other math concepts include patterns, sorting and sets, number recognition, shapes, comparisons, measurements, time, money, addition and subtraction. Throughout the day children use these concepts and learn math in ways that are natural for them. Simply playing with blocks introduces them to shapes. When they remind you that the big hand is on the 12 and therefore it is time for lunch; they are telling time. Most of what preschoolers learn about math does not come from dittos and worksheets. It comes from activities.
