Lesson 6: Even and Odd Numbers
This is a very easy, but very important topic that comes up again and again.
Don't forget to watch the embedded YouTube video clip for this lesson at the bottom of the page.
It's important to be able to indentify even and odd numbers. Memorize this topic.
A number that ends in 0, 2, 4, 6, or 8 is even. Examples are 376, 832, 790, 24, 6, 118
A number that ends in 1, 3, 5, 7, or 9 is odd. Examples are 267, 135, 81, 3, 889
All that matters is the rightmost digit: the digit in the ones place.
One way to help you remember even numbers is that if you have an even number of an item, you can divide it evenly among two people. If you have 16 pieces of candy, you and your friend can each have 8 pieces. If you had 17 pieces, it would not divide evenly, and one person would get one more piece than the other. That's why 17 it's called an odd number, and not an even number.
