Most classroom tool problems aren't pedagogical — they're logistical. The app requires SSO. The district hasn't approved it. The free tier ran out. The login takes five minutes of class time. So teachers give up, or make do, or build their own.
These tools exist because the gap between what's available and what students need is real. Strong mentor writing and frequent low-stakes practice matter. They shouldn't require a purchase order.
I'm an elementary school teacher currently teaching fourth grade at a Common Core school outside the United States. I teach all four core domains — math, science, social studies, and language arts — to the same group of kids every day.
I started building these tools out of frustration. The apps districts approve rarely match what students actually need, and the ones that do are usually locked behind SSO systems or paywalls that make them impossible to access. So I built my own.
Everything here was made to be used in my classroom first. If it works there, it's worth sharing. More tools are in progress.
