Frequently Asked Questions

Are 3rd graders ready for full-class collaboration?

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.

How long does a Mission take?

Most Missions run 30–45 minutes, start to finish. That includes the action, collaboration, and a quick debrief — all in a single class period.

Do I need special training to run a Mission?

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.

How much does it cost?

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.

How many students can participate?

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.

Will students actually enjoy this?

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.

What grade levels is this best for?

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.

What skills do students practice in Missions?

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.

Do I need to install anything?

Nope. Mission.io is web-based. All you need is an internet connection and devices — no downloads, no extra software.

Are Missions aligned to standards?

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.

What hardware is needed to run a Mission?

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.
