A Quartet of Drawings
Have students work in pairs. Give each student one of the lists of words below and explain that each list has one word with each of these prefixes: cent-, hexa-, milli-, and quadr-. Tell students to hide their lists from their partners. Then ask them to look up their listed words in a class dictionary and draw a picture of the object named by each word. Have partners exchange drawings and label each one with the name of the object illustrated and its definition. Let students refer again to a class dictionary if necessary.
