## The Lowdown | Understanding Inflation: A Stop Motion Explainer, Parts 1 and 2

Icon:

Explore a real-life application of percentage—the math behind rates of inflation—in two animated videos about inflation from KQED. The first video provides an overview of inflation; the second explains the role of inflation in a healthy economy. In the accompanying classroom activity, students find the price of a given item (e.g., a pair of jeans) this year, last year, 50 years ago, and 100 years ago and compare percentage price increase with total rate of inflation over each time period. To get the most from this lesson, students should be comfortable finding percentage increase and interpreting percentages greater than 100. This resource is part of the Math at the Core: Middle School Collection.

## Ancient Math & Music

Icon:

Explore how Pythagoras and Plato found mathematics in music and nature in this video from NOVA: The Great Math Mystery. The ancient Greeks identified three pleasing musical intervals: an octave, a fifth, and a fourth. Pythagoras discovered that the beautiful musical relationship between the notes was also a mathematical relationship: the harmonious sounds are produced by vibrating strings with particular ratios of string length. Plato believed geometry and mathematics exist in their own ideal world and that certain shapes (now known as the Platonic solids) were associated with the classical elements from which the world was made: earth, fire, air, water, and the universe.
