Keep preschool writing activities relaxed and fun. Don't expect or require perfection. Learning to write is a fun process that will give your preschooler a boost in confidence and solid foundation for future studies.
Do choose worksheets that are appropriate for the child's level, since children can get discouraged easily, if they are unable to perform the activity. Well illustrated worksheets with cartoons are also more likely to appeal to children. Worksheets that use common situations children come across at home, school, in the market place etc and that use common objects known to children would be more relevant.
Third grade can be particularly challenging when it comes to math, as this is the year that students are learning about fractions, measuring and weighing objects, graphing and counting money. Most importantly, third graders should be comfortable with the basics of math such as adding, subtracting, multiplying and dividing. If your child isn't comfortable with these basic components, it's almost inevitable that he or she will struggle with future math lessons.
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.
