Description
Greatest Common Factor and Least Common Multiple (GCF & LCM) Activity FREEBIE
Make finding the GCF and LCM fun with this code-breaker game. Students are asked to find the GCF or LCM of two or three numbers. Ideal as a bellringer or quick review activity.
The code is random to avoid your students attempting to guess a riddle rather than 'do the math'!
Follow me here on TPT where I have many similar activities!
Make it more engaging by offering a small reward for the first student to crack the code. This makes a great spiral review activity.
