How a Classroom Game Becomes an Embedded Assessment

Guest blogger Ross Flatt, a sixth grade teacher at Quest to Learn, demonstrates how studying geography with Galactic Mappers can be a viable strategy for embedding assessment in a classroom game.

Students are working on their a group project.

In Galactic Mappers, a social studies game about physical geography, students compete in teams to create the most geographically diverse continent in a shared hemisphere. This group mapping project encourages students to collaborate, design, iterate, and present a finished product in a single class period.

It's also a fun and informative way to assess my sixth grade students at Quest to Learn early in the school year -- and a powerful example of an embedded assessment that allows me to better support the learning process.

For anyone interested in learning more about Galactic Mappers or using games for assessment, here are some tips on preparation and gameplay from my experience using the game in my classroom over the years.

Embedding Assessment in a Game

Galactic Mappers provides many opportunities for me to assess my students, give immediate feedback, and track their learning across a class period as they attempt to reach their goal.

As they design their first continent, I might observe a group and note how easily they construct landforms without using notes or text. Better yet, I might see a student assisting her teammates. And I can always ask certain students to define the different landforms they are about to "unlock" as they play. In this way, the game enables me to clearly identify if any student is having difficulty understanding a concept, and then support or have a teammate support her.

The game also allows me to assess skills beyond content -- primarily social-emotional learning. Like most games, Galactic Mappers has time limits as well as winners and losers. In the time it takes to play a complete game, I can see which students are skilled time managers and collaborators, and how each student deals with frustration and challenges.

During gameplay, I check in with groups and individuals, and record observations. I use a rubric that assesses three areas:

  1. Geography Skills: Students can use a key and proper labeling skills, as well as demonstrate a firm knowledge of physical geography.
  2. Design: Students present a clear, neat, and visually pleasing continent that is appropriate for a map.
  3. Listening: Students have the ability to listen to their teammates and teacher, as well as be a positive force in their group.

Preparation and Planning

In order to successfully implement an embedded assessment in a game like Galactic Mappers, it's useful to lay some important groundwork in the days leading up to gameplay.


  • Content Preparation: First, students are required to come to class with a basic knowledge of maps and physical geography terms -- content covered in the weeks leading up to the game.

  • Strategic Grouping: It's important for the teacher to create balanced student groups that will function well. Students can also be assigned specific roles in their groups:
    • On-Task Manager: Manages materials, watches the clock, quiets group down when teacher addresses the class.
    • Scribe: Responsible for cutting materials, writing labels, drawing landforms and bodies of water based on map key.
    • Researcher: Looks up information in text or student notes when the group is stuck, examines classroom maps for design inspiration.
    • Presenter: Presents group's final design at the end of each round.

  • Transparency: Students should not be taken by surprise on the day of gameplay. As in test prep, they need to know what they are being assessed on, how the teacher will be assessing them, and possibly the format of the test itself. The day before we play Galactic Mappers, I show students the game cards, reveal the different rounds of play, and review student work from previous years. I make it clear that, while this is a game, it is also an assessment of their map skills, collaboration, and time management. They are aware that I will be asking them questions while they play and that I have high expectations for their teamwork skills.


Galactic Mappers is generally played during one 90-minute class period, but can be adjusted to fit different schedules. Gameplay is divided into several rounds that involve both group work and whole-class discussion. Opportunities for feedback and assessment differ in each round.

  • Round 1 (15 minutes): Students are given their supplies and initial continent, as well as first set of land cards. As they play, look for any initial group dynamic issues and check for basic understanding of gameplay. Reward some groups with extra land cards for demonstrating superior knowledge or excellent time management.
  • Presentation 1 (10 minutes): The class will circle around "the ocean" in the center of the classroom as each presenter shares out their group's continent and land cards. Reward each successful explanation with a Feature Card.
  • Round 2 (20 minutes): Students begin to place landforms and bodies of water on their continent maps, properly shading and labeling them. Start discussions with students about where and why vegetation might grow around certain feature cards (rivers, lakes), but not near others (buttes, mesas). With some groups, you may be able to have deeper discussions about where early humans might settle on their continent, while with other groups, you can talk more specifically about the basics of physical geography. (What is the difference between a river and a lake? A hill and a mountain?)
  • Presentation 2 (10-15 minutes): Students return to "the ocean" and place their finished continents on the class map. Presenters share out their continents and must correctly identify feature cards in order to earn points. Points are tallied and a winning group is announced.
  • Class Reflection (10 minutes): Before cleaning up the classroom, start a reflective discussion about the experience. Talk about the game itself, and what students may have learned from the experience. Try making a connection to future units, such as, "Where would people want to live on the map we created?"

Next Steps

I've been thinking about iterations on this game to challenge students further or teach different concepts -- for example, modifying it to focus on building actual continents or civilizations that students are learning about. While this may take away some of the more creative elements of the game, it would certainly ground it in the reality of the civilizations we will be studying over the course of the year.
