To start with, kids online games are arguably the best way to teach a child everything about letters and numbers. For instance, draw an incomplete picture of an animal or say balloon on a large piece of paper. Finish the incomplete part with dots. Ask the child to join the dots and complete the picture. Next ask the child to identify the animal. The entire process would keep a childs restless mind fixed.
Once done with, the child will have a growing urge to go for more of it. You can put this urge to good use. Teach the child numbers and alphabets with dotted lines. Likewise, you can teach the child spellings. While teaching a kid, make sure you give the child enough breaks. With regular breaks you can prolong the childs interest.
Introduce the child to spelling bee contests on TV. Partake in the quiz along with the kid to keep it interesting. In no time the kid will get hooked the program. Once the child likes it, you can replicate the program at your home. Prepare a whole list of names of animals, fruits, birds, vegetables, colors and even all that your child prefers like chocolates and candies. Make placards of spellings with some missing letters. As the child is familiar with game, he will be keen to fill the letters to complete the spelling. Start with easy spellings so that the child gets the thrill of answering successfully. You need to get more ideas on themes as you go along.
What matters the most in kids educational games is getting the child along your way. You need to be patient and at same time innovative.
