## Guides

- [Best free AI math help for elementary kids](http://127.0.0.1:3847/guides/free-ai-math-for-elementary/): Free elementary math in this directory, split into lesson apps and AI tutors. Khanmigo is paid. CK-12 Flexi is free, and younger than 6th grade was not established.
- [AI homework apps that teach vs. give answers](http://127.0.0.1:3847/guides/teach-vs-give-answers/): How this directory sorts homework apps: teaches, gives answers, or mixed. Photomath, Mathway, and Brainly produce the solution. Khanmigo and the lesson apps ask the child to do the work.
- [Reading apps for early readers (K-3)](http://127.0.0.1:3847/guides/reading-apps-for-early-readers/): Early reading tools for about kindergarten through 3rd grade already in this directory: Duolingo ABC, Khan Academy Kids, Ello, ABCmouse, Epic, and SplashLearn, with the limits we could verify.
- [Is my kid old enough? Age limits on popular homework apps](http://127.0.0.1:3847/guides/age-limits-on-homework-apps/): Age and grade limits copied from the public pages behind this directory. Brainly and consumer Grammarly start at 13. Khan Academy Kids is ages 2–8. Several apps require a parent account.
- [A parent's house rules for AI and homework](http://127.0.0.1:3847/guides/house-rules-for-ai-homework/): House rules drawn from how these apps actually work: when a solver is a parent tool, which products say 13 or older, and what a parent account is for.
