Sparki and Robomind for age 9-11

I have started a series of 8 lessons for initiation to programming and robotics, 1h15 each.
12 students of 9 to 11 years old, French speaking with basic English skills.
The first 7 weeks follow a Robomind academy curriculum: … _1_Desktop
The Robomind software teaches programming basics with a virtual robot. Robomind can generate Sparki code, so at the end of each lesson two kids can test their programs on the Sparki. (I have bought only one Sparki for now) Also, students learn to read the generated Sparki code.
For the 8th lesson, the idea is to write Sparki code directly. If you have any ideas for that one, let me know.
Thanks for your feedback and ideas!
