Activity 1: Introduce Number Line Scoot, Twos, Fives, and Tens

Purpose:

The purpose of this activity is for students to learn stage 1 of the Number Line Scoot center. In this stage, Twos, Fives, and Tens, Students take turns spinning a spinner and moving their cube that interval on one of the shared number lines. Students may use the number they spin to move that number of length units on one number line or decompose the number and move on multiple number lines. Each time a cube lands exactly on the last tick mark of one of the number lines, the player who moved it keeps the cube and puts a new cube on zero on that number line. The first player to collect 5 cubes wins. The work of this activity builds a foundation for addition on the number line in upcoming lessons.

Gather:

Centimeter cubes
Paper clips

Copy:

Number Line Scoot Stage 1 Directions
Number Line Scoot Stage 1 Spinner
Number Line Scoot Stage 1 Gameboard

Launch:

Groups of 2

Give each group a spinner, paper clip, centimeter cubes, and a gameboard.

Display spinner and gameboard.

“In this game, you spin the spinner and move cubes along the number lines. If you are the one to move a cube directly on the end of a number line you get to keep that cube. You can split your spin between more than one number line.”

“Read the directions with your partner.”

Answer any questions or demonstrate the game for the class if needed.

Student Work Time:

8 minutes: partner work time

Activity Synthesis:

Display a gameboard with several cubes close to the end of some number lines. Then spin the spinner.

“This is my gameboard and my next spin. Since I have to land exactly on the end of the number line to collect a cube, what move would you make on the gameboard?”
