General Activity Information
 Activity ID: 2599 Title: Is This Normal? Exploring The Normal Distribution Digital Tool/Resource: Quincunx Web Address – URL: http://www.mathsisfun.com/data/quincunx.html Overview: In this activity, students will be introduced to the Quincunx or Galton Board. The Quincunx is a device where marbles bounce off pegs and the chance of a bounce to the left or to the right is equal. The marbles fall into trays at the bottom of the device in a normal distribution. The students will complete a What Do I Notice?/What Do I Wonder? Table after playing the Interactive Quincunx. The purpose of the activity is to introduce students to normal distribution.This activity results from the ALEX Resource Development Summit.
