Lesson 1

Exploring Even and Odd Numbers

Est. Class Sessions: 1

Summarizing the Lesson

  • Should you and your partner get the same answer using different tools? Why or why not? (Yes. There should be the same number of pets no matter how you find it.)
  • What does each number in this number sentence stand for?
  • What keystrokes did you use for this problem?
  • How did you decide if your answer should be more or less than ten?
  • Were all of your answers reasonable? What did you do if they did not make sense?

Assign the Rooster's Addition Story Assessment Master for students to complete individually. Remind students to use labels to show what the numbers in their number sentences mean. Students can use pictures or words when labeling.

Assign Home Practice Parts 1–2 as homework after Part 2 of the lesson.

Read Rooster's Off to See the World by Eric Carle aloud to the class before assigning the Rooster's Addition Story Assessment Master. While the story is not a prerequisite for completing the assessment task, it does provide context for many addition situations. A rooster sets off to see the world and is joined by two cats, three frogs, four turtles, and five fish. After reading the book, addition problems such as, "How many animals in all set out to see the world?" can be created. Allow the use of counters, cubes, drawings, or calculators to solve the problems.

Use the Rooster's Addition Story Assessment Master with the Feedback Box to assess students' progress toward the following Expectations:

  • Compose and decompose numbers using drawings and number sentences [E1].
  • Solve addition word problems involving two or three whole numbers using tools [E6].
  • Represent addition situations with stories and number sentences [E7].

This assessment can also be used to assess students' abilities to use labels [MPE6].
