This will include counting to ten, recognizing shapes and colors, being able to hold a pencil or crayon properly, and coloring in without scribbling. Basic math concepts such as recognizing patterns, understanding quantity and some simple addition and subtraction will be useful.
Worksheets that include topics such as social and natural science will help to expand your child's horizons, teaching them about their environment and how things work, while improving their vocabulary at the same time. A worksheet about farm animals can initiate a visit to the farm area at the zoo, or to a real farm, where your child can explore and learn even more.
A step-by-step set of preschool worksheets will introduce new challenges to your child - skills and concepts they have not yet learnt. With your support and encouragement, your child will learn these new skills, achieve their goals, and gain confidence that will be vital when they start kindergarten or school. Starting 'big school' brings a lot of changes into a child's life, and your child needs to believe that he or she can face new challenges and cope well.
This sounds like an awful lot, doesn't it! A good set of preschool worksheets should cover all of this, and more. In the preschool years, repetition is the key to learning, but you should look for worksheets that teach the same skills in a variety of ways. This not only prevents boredom setting in, but also reinforces the concepts by encouraging understanding as well. The importance of reading to your child cannot be emphasised enough, and you should encourage them to 'read' as much as possible too.
