rectangle using multiplication
- Be better and
faster at doing your Multiplication (x) and Addition Digits (+)
Process
Before you begin, you can brush up on your multiplication facts at AAA Math

Today, we will review to do
simple multiplication. Since you are in fourth grade, you probably have
been dealing with multiplication for a while, right? Well, you will
need your multiplication skills today as you are going to help the
penguins build an igloo!
Building the Igloo: Step 1:
Finding Prices
First, you have to order the blocks from the Penguin Manufacturing Co.
The blocks cost 5 penguin-dollars each. You need 10 blocks to build the
igloo.
So, use multiplication to figure this out:
If that problem seems to big
for you to solve, let's use picture to help
you solve this problem.
Count each of the following
ice cubes, and add then up, being they are 5 dollars each...
If you can't add them up in
your
head, then just count ten times by fives. That should be pretty easy.
5,10,15,20,15,30...and so on
and so on.
To see the correct price,
click
this, but only once you have finished counting
HURRAH! You added up the price of the blocks, which is the
exact same as 10 X 5
See? Multiplication can be very, very fun. Now, it's time to put our
igloo together.
Building the Igloo: Step 2:
Finding Area
Ok, now we have to find the area of each block. Each block
has a width of 2 feet, and a length of 4 feet. Look below:
Finding the area of the block is easy peezy. All you have to do is
multiply the length (4) by the width (2).
So, your problem looks like this:
If you've done multiplication before, this is very easy. Just think 2
groups of four...
If you cant do 2x4 in your head, just count up the black dots.
The answer is 8. So the area of the blocks therefore is 8! See? That
was very easy. Now lets find the area of all the blocks. This may be a
little tricky.
Let's think. If their are ten blocks, and each have an area of 8, our
problem looks like this
Ok, so now we gotta add up the prices of all the equipment. So, the
problem looks like this:
If you have trouble doing the problem in your head, you might want to
work it out on a separate sheet of paper...
