Construction toys are a category of toys that allow children (and sometimes adults) to build and create structures, vehicles, and other objects using various pieces that can interlock, connect, or fit together. These toys often promote creativity, fine motor skills, spatial awareness, and problem-solving abilities. They can vary widely in complexity and materials, ranging from simple wooden blocks to advanced building sets with intricate components.
"Dolls" can refer to different things depending on the context: 1. **Toys**: Typically, dolls are toys designed to represent humans or anthropomorphic characters. They come in various forms, including fashion dolls (like Barbie), action figures, and baby dolls. They are often used for play and imaginative storytelling. 2. **Films and Literature**: "Dolls" can also refer to movies, novels, or plays that include themes involving dolls or use dolls as significant symbols.
Mathematical chess problems involve the application of mathematical concepts and reasoning within the context of chess. These problems can take various forms, exploring different aspects of the game, such as: 1. **Combinatorial Problems**: These may involve counting the number of possible positions that can arise after a certain number of moves or determining the number of legal moves available in a given position.
Mathematical games refer to a broad category of games that incorporate mathematical concepts, structures, or strategies. These games can range from simple puzzles and recreational math problems to more complex strategic games that require logical reasoning, combinatorial thinking, and problem-solving skills. Mathematical games can be both competitive and collaborative and can involve a wide variety of mathematical areas, including geometry, algebra, number theory, and probability.
Mathematical manipulatives are physical objects or visual aids that help students understand mathematical concepts through hands-on interaction. These tools can take many forms and are used in various educational settings to enhance learning, particularly in early childhood and elementary education. The primary purpose of manipulatives is to make abstract mathematical ideas more concrete and accessible for learners.
Mechanical puzzles are physical puzzles that typically involve manipulating parts or components to achieve a specific goal or solve a problem. These puzzles often require reasoning, dexterity, and spatial awareness. They can take many forms, including: 1. **Disentanglement Puzzles**: These consist of several interlinked pieces that need to be separated. Examples include metal wire puzzles or string puzzles. 2. **Assembly Puzzles**: These require the assembly of various pieces into a complete shape or object.

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.
