Materials and preparation

For this activity, you will need:
• Pencil;
• Paper or Cardboard;
• Tablet or smartphone (with an Android operating system). If you don’t have a tablet, you can do this activity on a smartphone, but it’s more complicated using these apps on smaller screens, like the ones on smartphones.

Ask an adult for help:
• Download and install the Assemblr app on the tablet or smartphone from Google Play Store;
• Download and install the Card Creator for CR app on the tablet or smartphone from Google Play Store;
• Print the cards that are created during the activity. We advise printing the cards on cardboard, so that they’ll last longer.
