Quality worksheets for preschool can help you with a lot more than just academics. For example, once your child starts kindergarten, they will be expected to sit still and complete tasks for about 15 to 20 minutes at a time.
These are basically digital versions (like ebooks) of worksheets that can be bought and downloaded to your computer from the internet or from CDs and then printed out. The advantage is that you can print out whichever sheet you wish. If you need to re-inforce a certain concept more you can usually print out that sheet again. Of course you will therefore need to have a computer and a printer.
Book knowledge is the ability to recognize book formats and purpose. Early readers learn how to hold a book properly, to read English from left to right, how pictures supplement the story, and that books have basic components such as a front and back, spine, pages, covers, and more. Children automatically learn these things at a conceptual level long before they understand the purpose of each component.
The homeschooling education should include a strong textbook foundation as well as a thorough instructor and lesson plan. The home school education should not be exclusively based on education of the instructor or limited to a curriculum purchased.
