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. 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.
Early training is easier and faster, To illustrate, if you shape clay while it is still soft, it will be easier and flexible, similarly the childs young brain is easy to mold. We can start training them while they are still inside the mothers womb. And when the child is born his brain is ready to learn. Child fast development takes place during the first year after his birth. He starts to recognize movements, sounds, shapes, colors, and even counts. So if you develop your child earlier the result will be better. kindergarten will be too late. Shape your child the way you want, If you want your child to be a good speaker, you must always read and speak to him. If you want him to be a musician or a simply a music lover, sing to him or let him listen to music. Hugs and touches together with words of "I love you" can make him a loving person. The more new things he will be exposed to, the more he will learn. Developing other skills require variety of different stimuli. Though your child may not necessarily be a genius but pre-schooling him means preparing his mind and equipping him with the tools he needed when he goes to school.
