There are many good workbooks available for kindergarten children. However with a regular workbook, a child can do each activity or worksheet only once. A good option is to use printable kindergarten worksheets.
When your child is ready, move on to pencil and paper. Build confidence by letting your preschooler trace simple lines and shapes, then proceed to letters. You can eventually teach your child to write his name by letting him trace or copy it daily. If your child needs help remembering how to spell her name, practice with fridge magnets, letter tiles or alphabet blocks.
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.
To get your child ready to tackle 3rd grade math with confidence, it's time to introduce learning aids at home. Most parents assume that worksheets, word problems and visual representations are the most helpful tools, but many forget the importance of online tools that offer educational value.
