# Student Videos

• #### Parallel and Perpendicular

Ian Byrd

Students learn about parallel and perpendicular lines and then hunt for examples of both in pieces of art.

• #### All About Lines

Ian Byrd

Students learn about lines, line segments, and rays with a focus on some fascinating aspects of infinity. In the end, they ponder what one type would think about another.

• #### Area of Triangles

Ian Byrd

In this lesson, students will deduce the formula to find the area of a triangle, then use that to decompose more complex shapes.

• #### Math Curiosity: Odds & Squares

Ian Byrd

Here's a math curiosity involving squares and odds that turns out to be true for every case.

• #### Investigating Cost of Living

Ian Byrd

Students will work with authentic data to investigate th

• #### Picking A Travel Destination Using Temperature

Ian Byrd

Students will produce a multi-line graph, calculate averages, and calculate ranges using positive and negative temperatures.

• #### Doubling Dollars

Ian Byrd

Students will double a single dollar once per day and discover how long it takes to reach \$1 million. Along the way, they'll move from repeated multiplication to using exponents.

• #### Improving Unclear Sentences

Ian Byrd

Rewriting passive sentences into active sentences makes them clearer, shorter, and more interesting. This video will help students to identify and improve these passive sentences.

• #### Fractals: Sierpinski’s Triangle

Ian Byrd

Sierpinski's Triangle is an example of a self-repeating shape known as a fractal. Students will learn to create their own as well as extend this idea into other shapes, leading to interesting math-based art.

• #### Fractals: Koch Snowflake

Ian Byrd

The Koch Snowflake is an example of a self-repeating shape known as a fractal. Students will learn to create their own as well as extend this idea into other shapes, leading to interesting math-based art.

• #### The Thinking Hats

Ian Byrd

This video introduces Edward de Bono's "Six Thinking Hats", tools that give people six specific ways to think when they're working with others: facts, emotions, positive, negative, creativity, and organization. They're perfect for improving small group and whole group discussions.

• #### A Donut Investigation

Ian Byrd

In this video, students investigate a strange image that asks which has more sugar: a donut or a health drink? What about a salad? Using math and language arts skills, they'll determine if this image shows a complete picture or is misleading.

• #### Jabberwocky and Context Clues

Ian Byrd

Using Lewis Carroll's poem Jabberwocky, students will try to infer the parts of speech and meanings of nonsense words. Then they can try their hand at their own nonsense poems.

• #### Propaganda and Logical Fallacies

Ian Byrd

In this series, students learn about five types of logical fallacies then develop an argument *against* a great idea, invention, or character using these techniques.

• #### Showing A Character’s Trait

Ian Byrd

We tell students to "show not tell" in their writing, but this advice isn't effective until they experience the difference. In this video, we'll write two examples of a scene: one showing a character's trait, and one just telling.

• #### Math Curiosity: Waring’s Conjecture

Ian Byrd

Students will tackle Waring's curious conjecture from 1762: all odds are either primes or can be written as the sum of three primes. After 250 years, we still don't know if it's true or not!

• #### Investigating Caffeine Part 3

Ian Byrd

In this final part of the caffeine investigation, students will analyze advertisements, and then create a public service announcement.

• #### Investigating Caffeine Part 2

Ian Byrd

Students, now armed with data about five caffeinated beverages, will survey a set of peers and/or adults to uncover misconceptions about caffeine.

• #### Investigating Caffeine Part 1

Ian Byrd

This is the first of a three part interdisciplinary math project. Students will be investigating caffeinated beverages, dangers of caffeine, and how advertising affects our perceptions.

• #### Eulerian Paths

Ian Byrd

Have students tackle the classic "Seven Bridges of Konigsberg" problem - can you cross each bridge exactly once?
