This zipfile contains notebook software and printable worksheets for a fun and informative learning experience about probability. The actvitiy invloves students spinning 2 different spinners and collecting data on the probaility of which color is more likely to land on. One spinner is a "fair" spinner with equally likely outcomes and the other spinner is "unfair" with outcomes that are not equally likely. Students spin the spinners, record & compare the data and answer the follow up activity questions. Great activity for a learning center or a stand alone lesson. I also have four other probability lessons posted on TPT that are great to accompany any probability unit. Check them out if you like.
