Look for and make use of structure.

In this lesson, students review place value to the billions using the context of populations. Students will read, write, and order large numbers representing the population of States. They will also play a game to practice reading large numbers.

Content in this Lesson

  • Reading and writing large numbers [E1].
  • Comparing and ordering large numbers [E2].
  • Rounding large numbers [E3].
  • Using benchmarks to estimate quantities [E3].
  • Representing large numbers using number lines [E4].
  • Using estimation to place numbers on a number line.
  • Developing number sense for large numbers.

Materials for the Teacher

Materials Preparation

Assemble Decks of Digit Cards or Playing Cards. Before the lesson copy enough digit or playing cards for student groups of three to use in the Spin and Read Big Numbers Game. Each group will need 3 sets of Digit Cards 0–9.

Spinners. If you do not have clear plastic spinners to place over two spinners for the Spin and Read Big Numbers Game, students can use paper clips and pencils. Straighten out one end of the paper clip and place a pencil through the curved end. Then put the point of the pencil on the center of the spinner and spin the paper clip around the pencil, using the straightened end as the pointer. See Figure 1.

Figure 1: Using a paper clip and pencil as a spinner

Cut Out Flash Cards. Prepare copies on card stock and have students cut apart the Triangle Flash Cards for the 2s and 3s and place them in envelopes. You may want to provide each student with two sets, one to use at school and one to take home.
