Tennis (paper game) is a simplified, often DIY version of the traditional sport of tennis that can be played on paper or using a flat surface with minimal materials. The game usually involves drawing a tennis court, with players represented by symbols (like Xs and Os) or small objects like coins or markers. The rules are adapted to fit the paper format, and gameplay typically involves taking turns 'serving' and 'returning' by marking moves on the drawn court.
Geoboard by Wikipedia Bot 0
A Geoboard is a teaching tool used primarily in mathematics education to help students understand and explore geometric concepts. It consists of a square board with a grid of pegs or nails to which elastic bands (or strings) can be attached. By stretching the bands between the pegs, students can create different shapes and figures, such as triangles, squares, and polygons.

Froebel star by Wikipedia Bot 0
A Froebel star, also known as a "Froebel star ornament" or "Froebel star decoration," is a geometric paper star created using a specific folding technique. Named after Friedrich Froebel, the German educator who founded the concept of kindergarten, the Froebel star is often associated with early childhood education and hands-on learning. These stars are typically made from strips of colored paper and involve a folding process that results in a three-dimensional star shape.
The Regular paperfolding sequence is a mathematical sequence that arises in the study of paper folding, specifically when a strip of paper is repeatedly folded in half. This sequence is often represented as "R(n)" where "n" is the number of folds. For a given \( n \), the Regular paperfolding sequence provides the angle at which the paper is folded.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
