In this lesson, students will deduce the formula to find the area of a triangle, then use that to decompose more complex shapes.
Here's a math curiosity involving squares and odds that turns out to be true for every case.
Students will produce a multi-line graph, calculate averages, and calculate ranges using positive and negative temperatures.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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!
In this final part of the caffeine investigation, students will analyze advertisements, and then create a public service announcement.
Students, now armed with data about five caffeinated beverages, will survey a set of peers and/or adults to uncover misconceptions about caffeine.
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.
Have students tackle the classic "Seven Bridges of Konigsberg" problem - can you cross each bridge exactly once?
In this video, we'll discuss how students can mentally prepare themselves for the big day and then look back on their work.
Now students will turn their outline into a storyboard and (pending your approval) move on to building their actual slides!
