 

I have a younger brother who drives me crazy! If I have
something or get to do something, he yells, “Me too! Me too!” When I play the
piano, he wants to play too. He even wants to play the same number of keys! My parents
always have to make sure they can split things equally between the two of us. Do you know
how they do this? 


My parents told me that there are even numbers and odd
numbers. If a number is even, it can be divided into two equal groups. If it is odd, there
will be one left over. Do you know how to tell if there is an even or odd number of
balloons? 



There are different ways to tell if you have an even or
odd number of items. One way is to group the items in groups of two. Are they all paired,
or is there one left over? When we imagine the balloons in pairs, like the picture at the
right, we see that one is left over. Therefore, the number of balloons is NOT even. Three
is not an even number. It’s odd. 



Another way we could have decided if we had an even or
odd amount is by using skip counting. When you count by 2’s, you are naming even
numbers. If we had done this we would have seen that three is not included. Therefore, it
is NOT even. Three is an odd number. 



I asked my mom to buy some strawberries at the grocery
store because I really like them. My brother yelled, “Me too! Me too!” My mother
says she will buy them if there’s an even amount so we can split them. I count, and
there are eighteen. Is this amount even or odd? Try making pairs or counting by 2’s
to decide. Click on the answer. 



When I ask for other things at the store, my mother
checks to see if the amount is even. Look to the right and decide if each amount is even
or odd. Click on the correct button. 



You have really learned a great deal about
classifying numbers as odd or even. I think you will find that this skill comes in quite
handy. I certainly use it a lot with my pesky brother! Now you can practice the skill by
completing an art project. Click on the crayons to see the directions for the project.
