### Other Ideas For Teaching The Real Number System

Playing Real Number Darts

(many variations)

Give students the number, for example Pi.
Have them either

1. ball the number up and throw it at the right position on the diagram (irrational).

2. Have them make a spitball and shoot it at the right position

Pin The Real Number Tail on The Diagram

Use a poster to draw a number system on the wall. Cut up lots of numbers and place them in a bag/box
Have students come to you and pick a number out of a bag and take a piece of tape
Have students tape the number in the right position on the diagram

Jumping Toward The Real Number

Use a poster or sidewalk chalk to draw a number system on the ground. Cut up lots of numbers and place them in a bag/box
Have students come to you and pick a number out of a bag.
Then have students jump to the right position

Using small basketball hoops (you may use cups, or boxes), label each hoop Irrational, Rational, Natural, Integer or Whole Cut up lots of numbers and place them in a bag/box
Have students come to you and pick a number out of a bag.
Have students shoot a ball to the correct hoop

Real Number Twister
(Get permission from administrator)

Using a poster draw the twister board as shown above. Label each circle , Rational, Natural, Integer or Whole. Ask for three volunteers
Call out random numbers to make them stretch and reach the correct category

Creating a Real Number Maze
Create a maze by hand or print one through puzzelmaker.com

Label each street Irrational Rd, Rational Rd, Natural Street, Integer lane or Whole Street

Pick a few random numbers (pi, -3, 0) that need to move through the maze. Students will need to navigate each number through the maze while paying attention to each street so that they don’t disobey the real number system. For example, the number zero may not navigate through any street named Natural because it would violate the number system.
