Get a whole bunch of "counters" or similar objects. count a few out (say nine of them), and see if you can share them evenly (fairly) between you both. Nine is not a fair or "even" split because one person gets 4 and the other gets 5.
All even numbers split evenly between the two of you and you each get a fair share.
All odd numbers fail to give you both a fair share.
Try it for all the numbers from say 9 to 30 and the kid will get to recognize that it alternates between "fair" (even) and "unfair (odd). If you keep a record of the odd numbers and the even numbers, the kid may be able to spot that when ever the number ends in a 0, 2, 4, 6 or 8 it must be an even number, but all other numbers are odd.
Get the point across by asking if say 201 will be even or odd.
If the kid can tell you that correctly, and for say 422 as well he probably has got to grips with the ideas of odd and even.

Show them. They need a visual. Flash cards work
but if you use something they understand, like toys its much more efficent because they can relate. Seperate 10 toys, like race cars. Show them how 1 is odd because he is alone. 2 is even because they can race eachother. 3 is odd because 2 can race but 1 has no one to race against. So on and so forth. If you do it every day, eventually you can start asking. Put a certian number of cars out and ask, is it odd or even? There really is no trick to it, its just like learning to count. Its all about memorizatoin. So if you give your child something they are already familiar with it helps. Barbie shoes work too, because Barbie has 2 feet.
There are several different ways.
You can tell the child to hold up a certain number of fingers, then tell them to "partner up" the fingers. If every finger has a partner, the number is even. If a finger lacks a partner, it's odd.
You can do a chant. 2,4,6,8,10 - even numbers let's say it again! 1,3,5,7,9 - odd numbers, oh my!
Also, each day...you and the child can determine if the day is odd or even, and explain why it is odd or even.
You can write them down and then have him say them over and over and them play a little memory game, flashcards, or make a little song about it.
Send them to school, hope the teachers do it for you :)))
