Care should be taken to give children worksheets that they are capable of doing. This involves understanding and monitoring the child continually, since the level of attainment of different children would often be quite different. The worksheet should challenge the child but not overwhelm her. If the worksheet is too easy or too repetitive, it may bore the child and she would not be happy. If the activity is too difficult it would frustrate her and she would not like to take up more sheets. The children should love to do the worksheets; they should not be thrust upon them. Also doing only worksheets alone repeatedly would not be very productive. You should have a range of physical games and activities as well that would reinforce the concepts learnt.
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.
