Students break down composite numbers into their primes and find GCF and LCM of two composite numbers in this activity that doubles as classroom decor. Included are 10 each of the following question types:
1: Find the GCF of 2 composite numbers less than 100
2: Find the LCM of 2 composite numbers less than 12
3: Prime factorize one composite number
To make is easier to differentiate, a couple of the pennants go above the 100 and 12 listed below but most stick to that standard.
Once a pennant is complete, it can be hung along a string in your classroom to show the world that, "Hey, we know how to find GCF, LCM and Prime Factors!"
Included are 32 pennants, an optional student answer sheet and an answer key. There are also plenty of places on each pennant for students to color. Each group of students can be given a set of pennants, scissors and either glue, tape or a stapler. Students can be in charge of cutting out the pennants. Groups can compete to see which group can complete the most pennants or your entire class can add pennants to one string as they complete each one. You may also choose to have your students color their pennants to add to your classroom decor.
