Ideally, children who have been introduced to reading modeling behavior enter kindergarten and first grade ready and eager to read on their own. For most children, the formal teaching of reading begins in these grades. Most educators, homeschool or otherwise, use a combination of phonics programs, worksheets, and actual books to teach reading. These are all tried and true methods and can result in reading success. A relatively new methodology, syllabics, extends the focus of phonics programs on the sounds associated with the consonant letters to simple rules for correctly using the variable sounds associated with the vowels.
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 comprehensive set of worksheets covering a variety of subjects can be used to expand your child's learning experience. A worksheet about shapes can be used as part of a game to find shapes around the house, counting worksheets can be used to count things you see in the grocery store and so on.
Almost everything you do with your child can be turned into an opportunity to learn - and worksheets can give you the guidance you need to find those opportunities.
