Materials Preparation

  • Number Lines. Display the class number line (0–130) where all students can see it and can reach it with a pointer. Tape a number line (0–100) on each student's desk for use throughout the year.
  • Number Line Target Game Learning Center. Place scrap paper, game markers, and the game directions in a learning center to provide targeted practice. Laminate copies of the Number Line Target Game Boards Master so students can record the moves in a round with a non-permanent marker then wipe them clean for the new round (optional).
