Speaker: Lots of things come in multiples.
You can look at multiplication as repeated addition.
For example, these cans are in 5 rows of 3.
Which you could think of as 5 times 3, or 3 + 3 + 3 + 3 + 3, or 5 + 5 + 5.
Here, there's 3 times 2, 3 times 1 and 2 times 3.
I need 5 nappies a day and I'm going away for 3 days.
5 for each day, 3 days鈥
5, 10, 15 nappies and 2 just in case.
Test your knowledge with this activity.
Speaker: This table decoration has 5 red roses in it.
But I need to make 10 of them which means I need 10 times as many flowers.
So that's 10 lots of 5, which is 10 times 5, or 5 times 10.
That equals 50. So I need 50 red roses.
Speaker: On average, we sell 144 red roses each week.
We are open 52 weeks of the year.
I want to know how many we sell each year.
That's 144 times by 52. If you don't have a calculator, the grid method can really help.
First, break down your numbers into hundreds, tens and units.
Then, do the multiplications for each square.
Then, I just have to add up the rows鈥
7,488 red roses. This is a very romantic town.
