Fin, Snoot and Plimble are fishing on the lake. They use division to share out their bait.
NARRATOR: Hello you three.
Gone fishing I see!
What are you trying to catch?
SNOOT: (ALIEN LANGUAGE)
NARRATOR: Oh, a bobble-eyed octopod.
Fascinating creature…
What are you going to use as bait?
SNOOT: (ALIEN LANGUAGE)
NARRATOR: Moon maggots, perfect.
How many have you got?
Let’s count them shall we.
1… 2… 3… 4… 5… 6… 7… 8… 9.
So, if there’s 9 moon maggots and 3 of you, to share them out you need to divide 9 by 3, which equals… 3.
FIN: (ALIEN LANGUAGE)
NARRATOR: Well if you’ve got a better way of doing it Fin, go for it.
I see, you’re going to count them out equally and make 3 rows of maggots, one row for each of you.
With all the maggots counted out, there’s 3 rows of 3 maggots each.
That’s a great way of dividing 9 by 3.
Just arrange 9 into 3 rows of 3.
BOTH: Aha!
NARRATOR: So, time to get these wrigglers onto the end of your fishing lines.
Oh no…
Looks like the octopod beat you to it.
Still, it’s nice to be out on the lake, isn’t it?
What is an array?
As array is a group of things arranged into rows and columns.
You can use arrays to help you divide one number by another.
Arrange the number of things you want to divide into the number of rows you want to divide by.
Count the number of things in each row to find the answer.
Example
10 ÷ 5 = ?
Make a group of 10 objects
Arrange them into 5 rows
How many are in each row? Did you get 2?
So 10 ÷ 5 = 2
