Mental Math Tips and Tricks - Addition FLEX

Please note this is the flex class. There are NO live meetings for this class. The material will be posted weekly and you can view it during the week at your convenience.

OVERVIEW: 
Mental calculations in your brain! Does that sound cool or what? Mental math is basically a way in which you can do math in your head and get to the answer fast! It is useful for all students especially those who have trouble with math. These techniques are used in both school and everyday life. I speak from experience, being an engineer and traveling all around the world, I use mental math everyday. It can help you answer questions like:

	• Do I have enough money to buy this bar of chocolate? (I love chocolate)
	• How many more points do I need to win the game?
	• How many grapes and almonds did I eat yesterday? (A lot)

In this class we will be covering mental math techniques for Addition. These skills will help us improve our number sense and get to the correct answer fast! We will start by learning techniques for adding 0 + 0 all the way up to 9 + 9. From there we will add bigger numbers.

INTERACTION:
Each week:
- I will send out a video and a handout which you should use to test what you learned that week. After finishing the handout students must send me a photo so I can double check it and give you feedback
- we will share what we each think is the most difficult strategy/trick/idea to implement that we encountered that week
- I will post a theme where each student must bring up a topic where they use math to count and the other students must respond to whether they use it in that situation as well
- you can test out the interactive game I made and see if you improve week by week
