This year’s Mathical Readathon theme is Powers of Ten, as we see how numbers of books read and shared can become huge as we all participate. If you’re new to thinking about the mathematical idea of powers of ten or just not sure how to explain it to others, we gathered a few helpful videos to explore the concept:
From Khan Academy (free online math tutoring with Sal Khan & others):
- Introduction to Powers of 10 (Video)
- Powers of 10: Patterns (Video)
From Generation Genius (videos made with the National Science Teachers Association):
