Jelly bean jarHave students guess the number of jelly beans in a jar. Then calculate the mean, median, mode, and range of their guesses. Make a box and whisker plot of their data. There is an excellent 10 minute video clip on the DVD called "The Code" to go along with this. Please see "The Code" under the resources tab for a slide show and additional information. Attached is the data for my classes. The jar was a 1 quart wide mouth jar filled with gourmet jelly beans. There were 797 jelly beans in the jar. I gave the jar of jelly beans to the student with the closest guess.

This 5 minute video clip shows proportions to demonstrate the size of an atom. Although it uses pictures instead of numbers it is an excellent resource to demonstrate proportions and equivalent fractions. An atom is to a grapefruit as a blueberry is to the earth. The students can visualize and recall these images for later discussions.

This slide show is about Thales of Miletus who stunned the ancient world by calculating the height of the Egyptian pyramids using proportions. It worked 2500 years ago and it still works today.
Have the students made a grid art project. You can have them measure two lines on the original picture and compare it to the corresponding lines on the enlarged picture to verify the proportions.

Do probability experiments and ask probability questions using coins, dice, and face cards.
|
Give each student 2 dice and have them roll them multiple times making a tally chart of the sums. Create a bar graph using the data. Also make a chart showing the possible outcomes. What is the probability of rolling a 2? What is the probability of rolling a 7? Etc.
