If you can't afford to enroll your child in Preschool, you can simply set aside a scheduled time each day to work with your child from home. This will allow your child to get used to the idea of sitting still and learning in a scheduled environment.
First off, reading with your child is one of the most important things you can do. Simply set aside a time each day to read a book to your child. Choose a quite uninterrupted time such as; before nap, before bedtime or after dinner time. Then allow your child to choose a random book each day. Be sure to read with much enthusiasm, as when you enjoy reading, your child will enjoy it too. However; one of the most important things to do when reading to your child, is to ask questions. Allow your child's mind to think of what will happen next etc. . This teaches children to comprehend, understanding what the story is all about and predicting what will happen next.
Teach your child to sing their abc's and say their 123's. Practice each day by singing and saying them together. Your child should be able to say their abc's before entering Kindergarten, as well as be able to count to 20 on their own.
Print out coloring pages online, so that your child can learn to color inside the lines. This will be great practice for Kindergarten. You can also print out shapes for them to trace, in order to teach them how to recognize shapes. This is something every child should understand before entering Kindergarten.
It is also helpful to have your child trace and practice writing their letters and numbers. Recognizing letters and numbers is very important. It's also helpful to introduce upper case and lower case before entering Kindergarten.
Teach your child the sounds of their letters. You can purchase educational videos online or have your child engage in free online activities in order to learn the sounds of their letters. This will help them prepare for Kindergarten, as by the end of Kindergarten most children will have started to read words on their own.
Last, it is not only important to mentally prepare your child for entering Kindergarten, it is also essential to physically prepare them, teaching them to use their motor skills, as well. Print out Preschool craft ideas online and have your child simply cut and paste different crafts. Simply teaching your child to cut a straight line and use glue will help them prepare for Kindergarten.
