Review of Multiplication
Think of it like this; take a group of 3 bottles of water and draw it 3 times. Then add them all up together.
The first number is the number of water bottles in the first group. EX; you would count out 3 bottles of water
The second number is how many groups to draw out or count. EX; you would copy your first group3 times.
The last number is your answer!

Great job! Now lets review one more time..
Correct Again!
You just used bottles of water to help you multiply! Good job! Now imagine if multiplied every bottle of water you drink a day by how many people are in the United States…Lets say you drink 3 bottles of water a day and that there are 315 million people in the United States today. What if every person in the US drinks 3 bottles of water a day as well.
Then we would have to multiply 3 x 315 million!!! And that equals a lot of water bottles being dumped in landfills somewhere. These water bottles do not break down very easily at all and take up a lot of space in the environment. So remember to recycle, reuse water bottles or buy a water jug that can be reused over and over.
Also remember when your multiplying to take your time and work it out on paper. Do not rush through it and accidently add or subtract the numbers.
