Lesson 5: Comparing Numbers


Activity 1: Would You Rather?

Pose the following questions. Ask your child to explain his answer to each one:
  • Would you rather have 10 dollars or 5 dollars?
  • Would you rather have 20 friends or 12 friends?
  • Would you rather have 18 cookies or 32 cookies?
  • Would you rather have 10 pieces of broccoli or 7 pieces of broccoli?
Allow your child to ask you similar questions, and explain your responses. Be sure to use the language "less than" and "greater than" in your explanations. For example, you might say, "I would rather have 10 dollars than 5 dollars because 10 is greater than 5."
Reading and Questions
Materials: More or Less by Stuart J. Murphy
Read More or Less by Stuart J. Murphy. Pose the given questions as you read. After you've read the book once and have gone through the questions with your child, reread it, and ask your child to provide more possible questions that Eddie could have asked in order to guess people's ages. For example, what else could he have asked on p. 13 about the woman's age?
  1. Stop at the bottom of p. 8 and ask your child, "What question would you ask next? Why?"
    Answers will vary
  2. After reading page 12, ask, "Why was Eddie smart to start at 42?"
    because he knew she was a grown up and he was using a grown up's age
  3. At the bottom of page 18, ask, "What should Eddie ask now? Why?"
    Answers will vary
  4. After reading the last page, ask, "What questions do you think Eddie should have asked Mr. Shaw? Why would those have been good questions?"
    Answers will vary
  5. When you've finished reading the book, look back at p. 7 where it says Eddie was "lucky." Ask your child if he thinks Eddie is lucky. Why or why not?
    Answers will vary
