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.
