Notes:
1. To ensure lesson plans can be sorted by date, please enter all dates in the format YYYY-MM-DD,
   including leading zeros: January is 01, not 1, for example. 

2. If you cannot find a date, use n.d. as the date (no date).

3. To ensure that the article/post will remain accessible for educators and students...
   a. Archive it at https://archive.org/web/ (use the "Save Page Now" form to generate a permanent URL).
   b. Paste that URL here as the source-archive-url.
   c. Enter the date you archived the source as the source-archive date.

4. Linking to a website helps the site. If the lesson plan is debunking disinformation, you may 
   avoid spreading disinformation by omitting the url of the original site entirely. In that case, 
   use the URL of the archived version as the value of source-url, and omit values for archive-url and archive-date.

==Activities==
''This is the main content of the lesson plan. Write as much or as little as needed to convey the main objective, the activities and tasks, and any other essential information. You may organize this content however you'd like.''

''You can use LaTeX to render mathematical symbols, such as <math>\sum_{k=1}^n k = \frac{1}{2}n(n+1)</math>. See the [https://en.wikiversity.org/wiki/Help:Formula Help:Formula] page for more details.''

''You may also wish to include helpful materials for an instructor, such as:''

* ''solutions to problems posed by the lesson,''
* ''anticipated points of confusion and suggestions,''
* ''discussion topics that may arise when working with students, or''
* ''any other relevant ideas or materials.''

==Assignments==
''You're welcome to suggest exercises, activities, assignments, or projects based on the material of this lesson.''

==Resources==
''(Include these sections at your discretion, keeping in mind that you and others can always edit and add more to these sections later.)''

===Background===
''You're welcome to share links to openly-accessible content (e.g. from Khan Academy, YouTube, Wikiversity, etc.) about domain knowledge or math skills students should have. Likewise, you may wish to include contextual information for the instructor.''

===Explorations===
''You're welcome to share references for additional learning and exploration, such as links to other articles, videos, spreadsheets, or computer code. When an open-access substitute is unavailable, links to paywalled sites are acceptable in this section.''

<!--CATEGORY TAG INSTRUCTIONS
Please follow these instructions so that people can find this lesson plan!

1. Select a primary event type from the following list:
business, culture, economics, education, finance, government, health, politics, science, technology

2. Select a primary math type from the following list:
algebra, arithmetic, calculus, combinatorics, geometry, logic, probability, statistics

3. Type your category tags directly underneath "[[Category: Eventmath lesson plans]]," 
at the bottom of this editor. For example, if you choose calculus and economics, 
you would have the following category tags on consecutive lines:

[[Category: Eventmath lesson plans]]
[[Category: Eventmath calculus]]
[[Category: Eventmath economics]]

NOTE: Be sure to use sentence casing for the category names (e.g. "Eventmath calculus" not "Eventmath Calculus").

FAQ
Q: Can I apply multiple event or math tags? 
A: Yes! For example, you might want both a probability tag and a statistics tag.

Q: Can I make a new category?
A: Yes! Just type it in the same format. Example: [[Category: Eventmath number theory]]

   However, this category will not automatically have its own display box on the Lesson plans
   page. If you think there should be one, you can add one. If you don't know how, leave a comment on the Lesson plans "Discuss" tab.

   Alternatively, you might interpret an existing category more broadly. For example, if you have a lesson plan for differential 
   equations, you might decide to include that under the calculus category. It's up to you.
