Human: Math Spinner, Arithmetic Wand, Extensible Snap Spinner Update: Added reinforced connectors with slight looseness for improved usability. Chamfered connectors on regular version for smoother handling. The math spinner is designed to inspire curiosity in children about mathematics. It may prompt them to ask questions like "What does that mod function do?" or "Is it valid to say 5 + 3 > -20?" It can be used as a random problem generator, providing an engaging way to explore mathematical concepts. Children often prefer problems they can relate to in the physical world. By incorporating snapping structures, I've created an extensible arithmetic spinner or math wand with four types of rings: 1. Digits (0-9), 2. Arithmetic operators (+, -, ×, ÷, mod). Modular arithmetic is a fundamental concept that simply involves keeping remainders. For example, 15 mod 7 = 1. 3. Relational operators (=, ≠, <, ≤, >, ≥) 4. Signs (+, -, blank/unsigned) 5. Cap 1 (optional) 6. Cap 2 (optional) Multiple sets can be printed, mixed and matched to create lengthy number sentences such as ### × ## = ##### or ## × # + # = ###. End caps are optional. When assembling the rings, please handle with care to avoid finger injuries. Gloves are recommended. To remove a ring after assembly, use a flat-end screwdriver and pry it off slowly. Have fun exploring math concepts with kids!
