Setting Children Up to Play Games

*PDF showing how to set up student accounts.

  • When setting up your classroom, the age group of your classroom will create a default set of games for your students.
  • When adding students to classrooms, you will create an anonymous username and password (image-based).
    • Document these usernames and passwords for your own records. For example, create a Word document with your children's names (not kept in the system), usernames and passwords (which are kept in the system).
    • **If you get an error (red outline around the student profile; profile will not save), then please add additional numbers or letters to the username. This indicates that the username has already been used.
  • Provide the username and password to the students, and to families if you want the children to play at home.
  • Students have their own login at the top right of the page.

Once an adult has created an account, a child can be added to a class with their own user name and image based password. Adults can also play the games directly from the Explore Games tab once logged in. The benefits of creating a child log in is that the password is image-based and it may be easier for a child to login and play independently. 

Levels, Leveling, and Reporting

Many child can have fun starting at Level 1. The age of the classroom will set your students up at a default level that will typically be challenging for their age group.

If those games are too easy, or when they are ready for more of a challenge, try the games at Level 2 and so on… 

You can assign a level of games to your entire class through the 'Assign Games' menu. *Note: This will focus the students on only the games you assign. 

Automatic Leveling and Reporting: In addition to your ability to estimate your students' level by going to the bottom of the Learn About page, two games (Help the Turtle Get Home and Subitize Planets) will automatically change difficulty based on how children are doing with the game. These games will also generate data in Reports. As children play, their answers to the games will be stored and generate some movement across levels - either up or down.
