Animator Shuyi Chiou and the folks at CreatureCast give an adorable introduction to the central limit theorem – an important concept in probability theory that can reveal normal distributions (i.e. bell curves) across data that does not appear to fit a normal distribution curve.

Students will practice calculating and interpreting z-scores, normal distribution, and standard deviation in real world contexts by working through these 20 task cards. These are challenging and diverse questions that require students to read carefully. 8-12 $

This is an interesting way to discover probability distribution. The probability that a marble dropped from above will land in a given slot is clearly visible.
