Cracking Codes: Cryptology for Kids- Spys
Students will learn the language of spies and secret agents in this children's cryptology class. Cryptology is the science of secret writing which uses math and reasoning such as number patterns, sequences, and symbols to create and decode mystery alphabets. Each week students will learn one or more ciphers and will practice using them to write coded messages to each other and to decode class examples. Code systems in Quarter 2 include grilles, invisible ink, cover systems, number ciphers, and alphabet ciphers.

Geometry Challenge: Polygons
What in the world as a hexacontatetragon? Learn to name polygons (and add to your vocabulary) using Greek and Latin prefixes. Finding the area of a rectangle is easy. When is it easy to find the area of a pentagon? Or the area of a dodecagon? Employing a variety of representational methods, including Venn diagrams, students explore the naming, categorization and characteristics of familiar and perhaps not-so-familiar polygons. Students are guided to discover facts and patterns regarding convex polygons, their angles and their areas. By inscribing regular polygons in a circle, students explore the idea of the circle as the limiting case of a sequence of regular polygons. Prior to beginning the class, students should be able to identify acute, obtuse and right angles, and be able to measure angles using a protractor.

Intro to Probability & Statistics: Surveys, Experiments, and Observation
How did the New York Times get it so wrong with the headline “Dewey Defeats Truman” in 1948? The answer lies in data collection. You need good data to draw valid statistical conclusions, and they didn’t have it! Why not? How have statistical methods in data gathering improved since then? What are the weaknesses that still exist? What do we need to be alert for when we listen to news reports? In this class students will learn about quota sampling, random sampling, and bias in data gathering. They will have the opportunity to gather a variety of experimental data. We will examine statistics in the news with a skeptical eye, looking for issues of self-selection in the sample space and other sources of data bias. Prerequisite—students should have a basic understanding of probability.
