Before discussing your the Check-your-understanding Questions, turn to your neighbor and describe what a multiple is.
When you both agree, take turns showing each other one problem you thought represented the basic idea of how to find a LCM.
Did you notice that sometimes the LCM was simply the product of the two numbers?
But other times, finding the LCM took making a list (or using the Ladder Method).
If you could make up a rule for when to multiply to find the LCM and when to not multiply, what would the rule be?
On the blank side, write your first and last name and U5T2.
1. Find the LCM of 8 and 12
2. Ananya likes to go to Starbucks every 10 days and Anika likes to go every 12 days. Ananya and Anika both went to Starbucks today. After how many days do they go to Starbucks on the same day again?

Notes
The secret I use to multiply large numbers mentally is called the Distributive Property.
First, I decompose one of the factors in the expression.
For example, in the expression 7 ⋅ 12, I decompose the 12 into 10 + 2. Then, I multiply the 7 by 10 and the 7 by 2 and add up the products.
7 ⋅ 12 = 7 (10 ⋅ 2)
* to prove that this works, you can simplify both sides to get 84 = 84
I want you to think of the next 10 problems like puzzles.
When you figure it out, be sure to share the secret with each of your group members.

Notes
#1 notice that the number outside of the parentheses is a common factor of the numbers on the other sides of the equals sign

Due 11/14
1. CYUqs (Be sure to do at least 8 of the medium questions!)
You are all going to do some of these. But, there are three things for you to keep in mind. First, do your own. Second, you choose where to start. Third, check your work with the students around you, and if you need help, get help. And if someone needs help, give help.
Check answers to make sure you are understanding
2. Be sure that your notes are your notes are up to date:
3. Stuck? Choose to persevere: review your thinking, try different approaches, ask for help, search
