Introduce: Conditionals Blue Level: Unit 3, Lesson 1
Lesson Overview
View Full Lesson Plan
Students will be introduced to the computer science concept of conditionals through plugged and unplugged activities. A variety of activities are included below to provide the teacher with choice around best supporting their students' comprehension of this concept.
Agenda
- βοΈ Introduce: Use the pages in the Blue Workbook to introduce students to conditionals. (5-10 min.)
- π€ Engage: Select from the activities below to engage students in learning about conditionals and what they do in computer programs. (35-50 min.)
- π Reflect: (5 min.)
- Thinking about the activities you tried today, can you explain forever loops to a friend?
- Can you think of any way forever loops are used outside of the classroom?
Materials
varies, based on the activities selected from below
Blue Level Student Workbooks, pp. 10-11
Unplugged Activity:
Conditionals in Scratch:
Conditionals with Dash and Dot
- Learn about conditionals using Dash and Dot robots with these Challenge Cards!
Conditionals in Code Studio
Vocabulary
- conditional: a statement that only runs under certain conditions or situations
Standards
- CA CSS 3-5.AP.12 Create programs that include events, loops, and conditionals.

Students will first use, then modify, a project exploring conditionals in Scratch using the TIPP & SEE model. This will provide students with another opportunity to tinker with this concept in Scratch before starting an open-ended project in the next lesson.
Agenda
- π« Review: Use the pages in the Blue Workbook to gain a deeper understanding of conditionals. (5-10 min.)
- π Explore: TIPP & SEE Conditionals: Mini Golf Scratch activity (35-50 min.)
- π Reflect: (5 min.)
-
How did the Mini Golf program help you understand conditionals in computer science?
-
How would you explain conditionals to another person?

Lesson Overview
View Full Lesson Plan
Students will continue the creation of an Amazing Mazes project in Scratch that will show their understanding of conditionals. In this second lesson of a three lesson sequence, students will continue building their project using Scratch, then pause to provide feedback in small groups on each other's Amazing Mazes projects, using that feedback to revise and finalize their work.
Agenda
- π« Review: Using conditionals to create an Amazing Mazes project in Scratch (5 min.)
- π₯ Mini-Lesson: Conditionals in Scratch (5 min.)
- π§ Build: Amazing Mazes project in Scratch (30-45 min.)
- π¬ Peer Feedback: Providing positive and constructive feedback on 2 peer projects (15 min.)
- π Reflect: (5 min.)

-
What did you learn from your classmates' projects feedback?
-
What did you discover from looking at other projects?

- initialize: assign a starting point for an object
- input: any information going into a program
- parallelism: sets of instructions that run at the same time
Standards
