1. Greatest Common Factor!!!
By: Jack, Megan, and Heather

2. What is a Greatest Common Factor (GCF)?
The GCF is the highest number that divides evenly into 2+ other numbers.
Examples:
7 and 13 → 7 x 1 = 7; 13 x 1 = 13 GCF = 1
6 and 10 → 6 x 1 = 6, 3 x 2 = 6; 10 x 1 = 10, 5 x 2 = 10 GCF = 2
42 and 63 → 42 x 1 = 42, 21 x 2 = 42, 14 x 3 = 42; 63 x 1 = 63, 21 x 3 = 63 GCF = 21

3. A Fruitful Activity for Finding the Greatest Common Factor
The goal of the activity is to get students to understand the concept of greatest common factor before being given the term definition.
Kids partition fruits into baskets to make as many baskets as possible of even amounts
Helps develop the rules of divisibility
Helps kids see that if two number don't have a common factor, it’s 1
Use of art helps engage further students

4. Article #2 Building from Prime Number
This activity helps students develop a base understanding of prime and composite numbers, and the procedures for finding prime factorization.
Students create numbers using blocks, only making new ones when necessary
Use of colored block make it easy to see differences
Helps kids see why 1 can’t be a prime number

5. Game! Get into 4 groups GOAL:
make as many trick or treaters as possible happy with even amount of the two types of candies you are given
