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.
Reading instruction is a component of the language arts curriculum that should be introduced across multiple subject matter content.

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.
