English:
- Play shiritor whereby the next person has to provide a word that starts with the last letter of the word provided by the preceding person.
- Choose a category e.g. animals. 1st participant provides a member of the category that starts with the letter A. Second participant provides one that starts with the letter B, etc.
- Go over the test results.

Observations: participants were very adept at constructing the circuits and then loading and running the tutorrial code.

Challenges: to make the class more interesting, I asked the participants to do an extra challenge, whenever possible, on every lesson. See above.

On the English part, the participants enjoyed the games.
