Today we are going to talk about EVEN and
ODD numbers. Its important to understand what the words EVEN and ODD mean.
An EVEN number is a number that can be paired equally. A pair means two, so when were
talking about EVEN numbers were talking about numbers that can be paired into twos.
An ODD number is a number that cannot be paired equally. An ODD number is a number that is
kind of left alone. Well talk about that more as we go through this lesson.
I went to a parade and I got some candy. I brought some home and now I want to figure
out if I have an EVEN amount of candy or an ODD amount of candy. I am going to put them
into pairs. Remember that pairs mean that I will put them into twos. I will put these
in a pair, these in a pair, these in a pair, and these in a pair. As you can tell, everything
here has a pair; and that means that this is going to be considered an EVEN number because
everything can be paired. So we have 1, 2, 3, 4, 5, 6, 7, 8; so 8 is going to be an EVEN
number. Now, lets say someone gets really, really hungry and they decide to come and
take these away from me. Now I have this much. Im not sure how many because I havent
counted yet, and I need to decide if its an EVEN or ODD number. Once again Im going
to try to put them into pairs. So I already have this pair, then Im going to take these
two and put them into a pair, and then Im going to put this one into a wait! I cant
put this piece of candy into a pair! Theres not another piece of candy to put it with!
Since I cannot put this into another pair, I realize that this is an ODD number. I cannot
pair this number. So 1, 2, 3, 4, 5 is an ODD number. I have two here, two here, and one
all by itself. 5 is an ODD number. Lets take a look at this whiteboard and
see how many EVEN or ODD magnets we have. Wait! I cant move these magnets! It looks
like were going to have to think of another way to figure out the EVEN and ODD numbers!
I have an idea! I can put them into pairs by adding a circle around twos when we
find twos. Lets do that together! Lets look at this top row right here and count
how many magnets we have. Heres 1, 2, 3, 4. Lets go ahead and put them into pairs.
This is a pair, and this is a pair. So 4 is an EVEN number because it can be put into
equal pairs. Lets look at the next row. Heres 1, 2, 3, 4, 5, 6. Some of you are
probably already catching on and you can tell right away. Is this an EVEN or ODD number?
Well, lets see! Lets put these into pairs and figure out if this is going to be
EVEN or ODD. Lets circle these two, and these two, and these two. Look! If you said
EVEN then you are right because they can all be put into pairs! Great job! There are 6
magnets here that can be put into pairs which makes 6 an EVEN number. Now lets look at
this last row. Heres 1, 2, 3, 4, 5, 6, 7. Lets go ahead and put these into pairs
to see if we have an EVEN or ODD number. Lets put these two together, and these two together,
and these two together and uh-oh. We can�t put this into a pair because theres not
another magnet to pair it with! Right away we should recognize that its going to be
an ODD number. We realize we cant put it with anything else, so 7 is an ODD number. Thank you for watching, please Share the video and Subscribe!
