Boethius (<a href="https://www.boethi.us/" rel="nofollow">https://www.boethi.us/</a>) is an app I made for my 7yo son to supplement his homeschooling curriculum. It involves completed "daily workouts" of exercises drawn from the seven classical liberal arts (grammar, arithmetic, astronomy, etc...).<p>The "Try Random Exercise" button lets you see immediately what it's like to use, but signing up is required to get most of the benefits, such as:<p>* A logical ordering of exercises (learn how to recognize nouns before learning about pronouns, learn what an argument is before learning the difference between validity and soundness, etc...),<p>* Spaced repetition (you review those you are struggling with most, but those you ace are brought up less frequently over time)<p>* Configuring your experience (select the number of exercises you need to complete each day for your "daily workout", whether to play audio by default or not, etc..)<p>* Creating any number of child accounts so you can keep tabs on your kids' progress over time<p>AMA
