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.
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.
Academically, parents can use preschool worksheets to help teach their children some of the basic skills they will need for kindergarten and school.
Make sure your child is not tired or hungry so that he or she can focus all attention on learning. Also try to keep the lessons consistent with what is being learned in school. A quick chat with the teacher or signing up for an online newsletter from the classroom are ways to keep tabs on the lesson plans.
