The first set of cards above, really are just for younger children who are looking for ideas. Younger kids don't cope with competition too well, so it's better if these cards are optional and used for inspiration. The other cards are great if you have your class in groups. Each group gets the first card. When they have created the same robot as is on the card, their teacher says "next card", or "not quite", until the group has worked through the whole set of cards. Another option is that one or two people in a group need to describe to the rest what is on the card. Without the rest seeing the card, they have to construct the same robot that is on the card, using Cubelets. This works well with set 3.
Cubelets Blockley App
For students who want to use Cubelets in a more advanced way other than just construction or remote control, you can actually code these things in Blockly and even the text-based C programming.
