Computer Science STEM Scratch Coding Semester Class

In this semester-long course, students will explore core programming concepts by designing interactive projects using Scratch, a beginner-friendly coding platform developed by MIT. Through weekly guided lessons, learners will take on the role of a game designer—planning, coding, debugging, and showcasing their own digital creations.

This class is perfect for beginners or intermediate coders ages 7–12 who want to grow their skills in a fun and structured environment. By the end of the course, learners will have a strong grasp of computer science fundamentals, increased confidence in problem-solving, and a portfolio of games and animations they built from the ground up.

What Will Be Taught?
Throughout the semester, learners will build a deep understanding of these essential programming concepts:

Sequencing – Understanding the logical flow of code and how to organize actions in the correct order

Loops – Using repeat blocks to reduce redundancy and increase efficiency in code

Conditionals – Making decisions with “if-then” statements and exploring how programs respond to different inputs

Variables – Storing and updating values, such as scores or timers, and learning when and why to use them

Cloning – Creating multiple copies of characters to build more complex interactions

Sensing and Events – Coding responses to user input, collisions, and signals within the program

Pen Extension – Drawing with code to enhance visual design and creativity

Debugging – Identifying and correcting errors in logic and structure

Each concept is tied directly to a themed project, giving learners a hands-on opportunity to apply new skills immediately and see results in real time.

Class Format & Structure
Each session is 55 minutes and follows a consistent routine to support focus and creativity:

Welcome and Introduction (5 min): Brief check-in, review of prior concepts, and a preview of the day’s goal

Live Coding Instruction (45 min): Students code alongside the teacher using screen sharing, with step-by-step guidance and time to explore customizations

Project Showcase (5 min): Time for learners to share progress, celebrate wins, and build presentation skills

We cap our classes at 6 students to ensure individualized attention and support. The class is highly interactive, and the teacher will actively check in with each student to help troubleshoot, offer ideas, and encourage deeper exploration.

Weekly Projects and Concepts Covered:

Week 1: Introduction to Scratch interface, sprites, and stage design (Chase Game)

Week 2: Using sound blocks for interactivity and timing (Dance Party Project)

Week 3: Sequencing commands to create a functional game loop (Climbing Game – Part 1)

Week 4: Extending sequencing logic with complexity (Climbing Game – Part 2)

Week 5: Introduction to repeat and forever loops (Surfing Game – Part 1)

Week 6: Using clones to increase challenge and responsiveness (Surfing Game – Part 2)

Week 7: Drawing with code using the Pen Extension (Dolphin Game – Part 1)

Week 8: Sensing player input and character proximity (Dolphin Game – Part 2)

Week 9: Motion blocks and coordinate logic (Snake Game – Part 1)

Week 10: Creating and updating variables to manage game scoring and levels (Snake Game – Part 2)

Teaching Style: 
The teacher provides a blend of direct instruction and exploratory learning. Lessons are paced to ensure learners understand each new concept before applying it, with frequent check-ins and guided questions to prompt critical thinking. Students are encouraged to customize their projects, try new ideas, and embrace mistakes as learning opportunities. Peer-to-peer encouragement is also fostered through show-and-tell time at the end of each class.

Student Interaction
This course is designed to be hands-on and collaborative. Students will:

Code live with the instructor and receive real-time help

Ask and answer questions throughout the session

Share their projects with the group

Receive personalized feedback from the teacher each week

Note: iPads are not recommended with this class. Students will need a keyboard.  Please make sure an adult is on hand for the first five minutes of class to help set-up and tackle troubleshooting.
