Lesson 5

Growing Patterns

Est. Class Sessions: 1–2

Summarizing the Lesson

Compare Growing Patterns. Display a completed Hopping in Patterns page or other growth patterns recorded during this lesson.

Ask:

X
  • What is different about each of these growing patterns? (Some grow larger and some grow smaller; the size of the hop is different in each one; the start of the pattern.)
  • If you start at zero, how many hops of five will the math hopper need to make to land on 20? (4)
  • If you start at zero, how many hops of two will the math hopper need to make to land on 20? (10)
  • Why did the number of hops get larger? (Possible response: The hops got smaller; it takes more little hops to get to the same place.)

Play What Is My Pattern. Display the What Is My Pattern Game page from the Student Activity Book. Tell students that you will be Player 1 and select one student to be Player 2. Show four hops and circle four numbers on the first number line to show a growing pattern (e.g., 6, 8, 10, 12). Ask Player 2 to extend the pattern by circling four more numbers on the number line. Player 2 should then record the pattern in the boxes below the number line. If Player 2 records the pattern correctly, it is now his turn to choose a pattern to represent on the number line and for Player 1 to extend and record the pattern. If the pattern is not extended and recorded correctly, Player 1 leads the next round again.

After demonstrating a few rounds of the game, direct students to use the What Is My Pattern Game pages in the Student Activity Book to play several rounds of the game with a partner. Student pairs can play six rounds, three on each page, and save the remaining three game boards to play at home with a family member.

For the What Is My Pattern Game, draw a two-sided math hopper. Player 1 can place the math hopper on the number line either at the beginning, facing left, or facing right, depending on whether the pattern is decreasing or increasing.

Assign the Add to the Pattern page in the Student Activity Book.

X

Use the Add to the Pattern page with the feedback box in the Student Activity Book to assess students' abilities to identify, describe, and extend growing patterns [E4]; represent patterns using number lines [E6]; and count forward and backward by ones, twos, fives, and tens [E1].

Use the What Is My Pattern Game page to provide targeted practice with extending and representing growing patterns with number lines.
