This Skittles Probability Investigation Activity explores both experimental and theoretical probability through investigating the claim that there are more red Skittles than any other colour in each packet.

Students use their own fun size packet of Skittles to make predictions, theorise and calculate expected value, construct bar graphs, frequency tables and make conclusions about the claim.

The files included are as follows:

• Skittles Investigation Booklet
• B&W Skittles Investigation Booklet
• Differentiated Skittles Investigation Booklet
• B&W Differentiated Skittles Investigation Booklet

The regular investigation booklet includes:

• Making predictions
• Constructing Bar Graphs
• Theoretical Probability
• Calculating expected value
• Frequency Tables
• Experimental Probability
• Distribution
• Disputing claims using mathematical reasoning

The differentiated booklet removes expected value and uses familiar vocabulary when describing distribution.

In order to implement this in your classroom, you will need one booklet printed per student/group and one fun size packet of Skittles per student/group.

The full booklet can be seen in the preview, so feel free to have a look!

My students love this activity and are always engaged, especially with their predictions and counting their Skittles! It is a lovely way to end the term or the probability unit. I hope your students love it as much as mine do!
