Type: Lesson/Unit Plan

Overview:

The class programs their sprites to interact in new ways. After a brief review of how they used the isTouching block, the class brainstorms other ways that two sprites could interact. They then use isTouching to make one sprite push another across the screen before practicing with the four collision blocks (collide, displace, bounce, and bounceOff).

Content Standard(s):
Digital Literacy and Computer Science
DLIT (2018)
Grade: 6
5) Identify algorithms that make use of sequencing, selection or iteration.

Examples: Sequencing is doing steps in order (put on socks, put on shoes, tie laces); selection uses a Boolean condition to determine which of two parts of an algorithm are used (hair is dirty? True, wash hair; false, do not); iteration is the repetition of part of an algorithm until a condition is met (if you're happy and you know it clap your hands, when you're no longer happy you stop clapping).
