Here’s a quick & visual way to DISCOVER least common multiples
DVDs and ATMs
LOLs, SMHs, and LCMs!
Oh, the power of initialisms! We can express much in only three letters!
If not for these 3-letter combinations, we mathematicians would have to constantly voice “least common multiple” verses the effortless “LCM!”
Why say “Digital Versatile Disc” when you can utter DVD (remember way back when)? Don’t waste your precious breath articulating “Automated Teller Machine” when you can enunciate ATM. Why type out “Shaking My Head” when SMH will do, or what about the classic LOL? Am I right? With initialisms, we’re saving time all over the place!
Introducing (drum roll) another triple-letter combo to the team: LCM, meaning “Least common Multiple!” Woo Hoo!
In this video lesson, Math Specialist Amy employs unifix cubes and color-coding, clearly aiding us to visualize the pure essence of “Least Common Multiple” or LCM! She digs into the etymology, the root of the word, “Multi,” meaning “many!” Then up from the vocabulary depths, we climb and venture into applications: Adding, subtracting, comparing, and ordering fractions! This is good stuff, people!
Quality indeed! This is our classic, compassionate method of teaching!
Speaking of fractions, have you tried out our Stress-FREE Fraction Course? There will be no SMH or FBI!
