Fin, Snoot and Plimble try different ways to divide up their destructor bots.
NARRATOR: Hello Snoot.
SNOOT: (ALIEN LANGUAGE)
I like your destructor bots.
Ah look, it’s Fin and Plimble.
PLIMBLE: Plimble!
NARRATOR: Have you come to play?
Snoot, why don’t you share out destructor bots between 3 of you, so you can all play?
NARRATOR: Come on, Snoot.
It’ll be much more fun with 3.
SNOOT: (ALIEN LANGUAGE)
NARRATOR: So, there’s 3 of you, and there’s 12 destructor bots altogether.
So you need to work out, how many times does 3 go into 12?
The answer is 4.
FIN: (ALIEN LANGUAGE)
NARRATOR: I see you’re not satisfied Fin.
Do you want to have a go at dividing them up?
As there’s 12 bots and 3 of you, you prefer to take away 3 from 12 until you’ve got none left.
1 group of 3…
2 groups of 3…
3 groups of 3…
4 groups of 3.
That makes 1… 2… 3…
4 groups of 3 altogether, which means 12 divided by 3 equals 4.
BOTH: Aha!
NARRATOR: That’s a really great way of working it out.
To find out what 12 divided by 3 equals, just keep taking away 3 from 12 until you’ve got none left.
The amount of times you can take away is the answer: this time, 4.
Now then, let’s play.
I’ll count down from 3.
Everyone ready?
3… 2…
Bit quick on the draw there Plimble…
PLIMBLE: Plimble!
How can subtracting help you divide?
If you have to divide a number you can get the same answer by taking away the number you are dividing by over and over again.
Example
What is 10 ÷ 2?
Find the answer by taking 2 away from 10 again and again until you can't do it any more.
10 - 2 = 8
8 - 2 = 6
6 - 2 = 4
4 - 2 = 2
2 - 2 = 0
You have taken 2 away 5 times. So 10 ÷ 2 = 5
How can adding help me with subtracting?
While juggling, Fin and Snoot learn that subtraction is the opposite of addition.
