Parallelism

Sprite

Code

Algorithm

Vocabulary

Engage: Play the Simon Says game with the Simon Says Cards. Have students predict and act out the different motions. They can only move if they see a green flag code block..

1

Introduce: Show students the sample project. Ask what caused the sprites to start moving? (Click the green flag”) Connect with the Simon Says game experience.

2

Model: Demonstrate how to add a second sprite, add the flag event with some motion blocks. Ask students to predict what will happen when the flag is clicked. Observe that both sprites begin their movements at the same time. Define parallelism.

4

Model: Demonstrate how the flag event goes at the beginning of an algorithm. Show how clicking the flag at the top starts the action.

3

Code: Encourage students to add at at least 3 sprites to their project with algorithms for each. Use the flag event to start the motion for all the sprites at the same time.

Activities/Extensions

Have partners get together and follow each others algorithms with physical movement. Talk about Collaboration and how to work together and how it relates to coding and how when the characters are dancing together they are working together. Discuss about how you can work together to help solve problems and how dancing each others dances that they had to work together. Here are some sample videos you could watch about teamwork and collaboration.
Teamwork by Robert Munsch
A Little Spot of Teamwork by Diane Alber
Leadership and effective collaboration (several short examples)
