Show your students the number line from the first page of the Number Line Riddle worksheet.
Have your class think, pair, and share a three-letter word and its corresponding fraction or decimal on the number line (an example might be "car," where c is 3/4 , a is 1/4 and r is 4 2/4 or 4.5). Note how the number line is missing certain whole numbers; it’s tricky!
Let your students share out their answers with the whole class and challenge them to list both fraction and decimal form of their corresponding letters.
