In this animated activity, learners view the various hand, arm, and shoulder muscles in action. The students test their knowledge of the location of the muscles in a drag-and-drop exercise.

In this fourth part in a series, learners follow the steps of the “mathemagician” to examine three numerical curiosities: Be a Psychic by Predicting Birthdays, Predict a Card with Mind Reading, and Predict the Three Die Values Your Opponent Has Rolled. Learners will also study palindromic numbers and look at two alphametric puzzles.
