Frequently Asked Questions
Definitely. By 3rd grade, students are ready to move from basic turn-taking into real group problem-solving. Missions give them the chance to organize roles, compare solutions, and begin making collective decisions as a team.
Most Missions run 30–45 minutes, start to finish. That includes the action, collaboration, and a quick debrief — all in a single class period.
Not at all. Missions largely run themselves. Your role is more of a “guide on the side”—supporting students as they problem-solve together. We provide a quick-start walkthrough, a built-in library of short training videos, and even live chat if you need us.
Creating an account is free. You’ll get full access to the entire library for 30 days, then ongoing free access to rotating Missions that support our research. Upgrading is totally optional — no strings attached.
Missions are built for full-class collaboration. They’re optimized for 12–30+ students working in teams, but we can help you adapt if your group is larger or smaller.
Yes — and then some. Teachers consistently tell us that students beg to do Missions again and again. The stories, teamwork, and “we’re in it together” vibe make it one of the most engaging things you’ll ever do in class.
Our library is strongest in K–8 STEM, but every Mission also builds teamwork, problem-solving, and higher-order thinking. That means educators at any grade level can use Missions for collaboration and skill development.
Beyond academic content, students develop collaboration, communication, critical thinking, and resilience. These “real-world” skills are measured alongside knowledge to give you a complete picture of learning.
Nope. Mission.io is web-based. All you need is an internet connection and devices — no downloads, no extra software.
Yes. Every Mission is built around grade-level standards (with our strongest alignment in K–8 STEM) so the collaboration isn’t just fun — it’s academically rigorous and connected to what you’re already teaching.
Each student will need an internet-connected device (laptop, Chromebook, or tablet all work). You’ll also need a projector or large display at the front of the room so everyone can follow the story together, plus speakers or classroom audio. That’s it — no special equipment, downloads, or extra software required.
