Lesson 3 Word Knowledge
impossible
• Explain that the prefix ‘im’ means not.
• Explain the difference between possible and impossible.
•Brainstorm things that can happen vs. those that cannot happen. Elicit from students things
that are possible for people to do and write them on a large chart. Have students illustrate
their responses on cards. Show the students that if you add the prefix ‘im,’ it means not.
• Ask the students about things that they think are impossible to do. Write these on a chart and
have the students illustrate their responses. After all the illustrations are complete (both
possible and impossible), mix up the picture cards and have the students sort them into two
columns: possible and impossible.
•To reinforce the word believe, when you review each statement or picture, say: “I believe/
don’t believe that could happen.”
• Review the concept of what animals can and can’t do. Emphasize impossible tasks.
• Discuss some other words that begin with the prefix ‘im’ meaning not: impatient
(remind students that this is another key word in the story) and impolite.
•You may also choose to look in a dictionary with your students and point out that there are
several other words that begin with ‘im’.
electric blankets
• Explain that electric blankets are blankets that use electricity to become warm.
•Discuss what electricity is and how it works. Look around the classroom and point out things
that use electricity to work.
•Discuss and list things that can be electric: blankets, typewriters, appliances, lights, some
cars, radios, lamps, computers, vacuum cleaners, etc.
•Math activity: Have students keep track of how many times they use something that needs
electricity during a day? How many times at home? How many times in school?
