This "secret message" activity will amuse your students and teach them about finding the least common denominator for two fractions.
Directions are printed at the top: In each row, determine the least common denominator for each pair of fractions. Circle the letter next to the LCD with the greatest value. The first one has been completed for you.
At the end, read the message from top to bottom. It reads, "Now we could add" (The other letters spell "List multiples").
These 13 problems involve fractions with denominators ranging from 2 to 15.
And all you have to do is copy it! The rest of the prep is all done for you.
