Recently we’ve been learning all about integers. Integers are any whole number but can be positive, negative or zero. For example, -30, 4, 0, -7 and 182 are all integers. 3.82, 1/4, .5, and 7/4 are not. Those are considered to be rational numbers which are any number that can be turned into a fraction with integers as the numerator and denominator.

In the past we’ve done plenty with addition and subtraction. We’ve added and subtracted decimals, percents, and fractions this year. Most recently we learned how to add and subtract integers. Integers can be tricky because you can end up with both positive and negative numbers in a problem. However, we took a look at how to use number lines to help us solve the problems as you’ll be able to see in the videos we created.

After using number lines to understand the concept behind adding and subtracting integers, we took a look at other ways to solve the problems. We started with adding integers. Adding two negative numbers is very easy. We learned that to find the answer, you just add the two numbers and make the number a negative. For example – 3 + -5 = -8 because you’re going back 3 and then going back another 5 which puts you at -8 on a number line. If you have one positive number and one negative number, there are a few more steps involved.

After we discovered how to add integers, we took on subtracting integers. We learned that a subtraction sign can almost be looked at as the opposite of. For example, if you take away four of something it’s the same as the opposite of having four. We used this idea in helping to figure out problems dealing with subtracting positive and negative numbers.

Of course, some of newscasters from the Math Movie Network can probably explain it even better. Take a look at the videos below to learn a little bit more about adding and subtracting integers!

As always, an amazing job by our Math Movie Network hosts! Can’t wait to see what else you have in store this year!

**Which way do you prefer to solve problems with integers?**

**Where are some different places that you may find negative numbers?**

Dear Mr. Avery’s class,

I learned so much from the video. It reminds me of my math class at my old school. There must be a lot of circles in the world. This is important if you work on a construction job. You need to use geometry for cutting the right size to cut the wood.

Dear Mr. Avery,

I had a lot of trouble at first with adding and subtracting integers but it has been more clear since we started learning more about it. Like Allison, I also can’t wait until the bloopers video comes out. I am still sad…..

Dear Mr. Avery’s class

You all did a great job on the videos. I can’t wait until the blooper come out to the subtracting integer. When you said you were video taping I could not stop laughing.

Dear Mr. Avery,

I think these videos are awesome! A good job to Anna, Emma And, Moriah for the subtracting integers video. And for the adding integer video a great job to Ed, Kevin, Alexandria, and Faith. One place you might find negitive number is at the bank if you are in debt.

Sincerely,

Morgan

Dear Mr. Avery,

I loved the idea of making these two videos a Super Bowl edition to the Math Movie Network! GO PATRIOTS! Iloved the little symbol at the end of our classes video. I like integers too! I really think I understand them! The way you teach makes it easier for me to learn. I do better when I have fun doing it! I also cant wait for the field trip on the 9th! The science museum is so much fun! The Omni Theater is super cool. I cant believe that we get to see the volcano video! Then, we get two more trips at the end of the year plus more tutorials videos! This year’s been awesome and is going to get even better!

Nice job on the integers video! I thought it was very funny how Moriah had to run back to the introduction stage! Nice job everybody! Go Patriots! ๐

Dear Emma,

Thank you for commenting. I also liked the part were Moriah had to run back to the the green screen to do the ending.:mrgreen:
