Stages

Discussion of solutions of additional tasks from Module I

Time to complete this part: about 15 minutes

At the beginning of the lesson we remind students what they were supposed to prepare between classes. We invite a volunteer to present his/her solution. We ask if anyone had a different way of finding a solution. We discuss the solutions (praising correct solutions to individual tasks).

If there was no homework, we start by repeating key issues from the previous module. We also ask if students have any doubts regarding their own projects. If anyone wants to show something he/she is proud of, we let him/her do it.

Introduction to the game scenario, changing the stage background and adding a new sprite

Time to complete this part: 15 minutes

We introduce the students to the lesson topic, which is to create a simple game with the characters of the Kitten and the Mouse. The Kitten’s task will be to catch the Mouse, who is to avoid being caught for as long as possible.

We remind students that during the previous class we learned how to change the appearance of the sprite, and animated it by changing its costume.
