Home schooling can be expensive and difficult to implement, especially on a tight budget. If money is tight, homeschool worksheets that you can get for free can take the place of a textbook. The worksheet will be able to teach pretty much the same things that a textbook will, and yet you would not have to spend hundreds of dollars on books. Although some worksheet resources charge a small fee, you will be able to access thousands of printable worksheets that you can use for homeschooling.
There are also teachers who use these kinds of techniques to teach in a more animated manner. The idea is to keep children interested because without their attention, it is difficult to make them absorb what you are trying to teach.
