Subject: Re: even numbers to asix year old


The way I was taught about that time was that the teacher used
something like domino patterns to show the even and odd numbers. 

For example, 2 can be represented by a pair like a marriage.

Three is a pair plus 1.  The extra 1 doesn't have a mate or friend.

Five is two pairs and one extra.  The odd numbers always have an extra
spot.

For older kids, you might explain that 2 times any number is always
even.  If that is so, then 2 times any number plus 1 is always odd.  

That idea helps in algebra sometimes.
