The same children can play the games but in different ways, since the programs are tailored toward the learning styles of each child. This is what makes adaptive learning an essential tool in classrooms as well.
Kindergarten worksheets are often of much value in helping kindergarten children learn and re-inforce basic concepts in an interesting way. Small children usually like to do things rather than just read or listen. They also get bored rather easily. Therefore giving them well-designed, illustrated worksheets to do makes it easier and more fun for them to learn. Completing a worksheet also gives a child a great sense of fulfillment. In fact, not just for kindergarten, but even for older learners worksheets can form a valuable part of the learning process.
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.
If your child is used to doing a worksheet or two, they will be able to do this quite easily, and will understand that they need to complete the task before they can move on to the next activity. Worksheets also help your child to learn how to follow instructions, and teach them about following rules.
