Data and Probability Games for Grades 2‑8

Data and probability help students make sense of the information around them. In these games players collect tallies, build bar graphs and line plots, find the mean and median and see how an outlier pulls them around, and run spinners to compare what should happen with what does happen. The habit to build is asking what a set of numbers is really saying. The games are short, work on a Chromebook or a phone, and give instant feedback on every answer.
