Grade 3 Coding and Robotics – Introduction to Basic Algorithms
Materials Needed:
1. Interactive whiteboard or projector
2. Laptops or tablets for each student
3. Scratch Junior software or an equivalent block-based coding program
4. Printed worksheets with step-by-step coding tasks
5. Flashcards with coding terminology
6. Pencils and erasers
7. Pre-made robot models (optional for demonstration)
8. Chart paper and markers for group activities (optional)
Learning Objectives:
1. Understand the concept of algorithms as a sequence of steps.
2. Identify and use basic commands in a block-based coding environment.
3. Apply logical thinking to solve simple coding tasks.
4. Collaborate with peers to complete coding challenges.
Vocabulary:
1. Algorithm – A step-by-step set of instructions for performing a task.
2. Command – An instruction given to a computer program.
3. Sequence – The order in which commands are executed.
4. Loop – A set of instructions that is repeated.
5. Debugging – Finding and fixing errors in the code.
Previous Learning:
– Basic computer navigation skills.
– Familiarity with the concept of instructions and directions.
– Prior exposure to problem-solving activities.
Anticipated Challenges and Solutions:
1. Challenge: Limited understanding of abstract coding concepts.
Solution: Use tangible examples and visual aids.
2. Challenge: Difficulty in following multiple-step instructions.
Solution: Break tasks into smaller, manageable steps and use peer helpers.
3. Challenge: Technical issues with devices.
Solution: Ensure all devices are charged, software is pre-installed, and tested beforehand.
Beginning Activities (10% of time):
1. Introduction (5 mins): Begin with a relatable discussion on algorithms by comparing them to daily routines (e.g., brushing teeth, making a sandwich). This helps ground abstract concepts in familiar experiences.
2. Engage (5 mins): Show a short, engaging video illustrating how robots follow instructions (e.g., a simple robot performing tasks).
Middle Activities (80% of time):
1. Direct Instruction (10 mins): Demonstrate basic algorithms using Scratch Junior on the interactive whiteboard. Explain fundamental commands such as Move Forward, Turn Left, and Turn Right, using real-life examples for clarity.
2. Guided Practice (20 mins): Distribute laptops/tablets. Guide students through a simple coding task using Scratch Junior—creating a character that moves in a square. Provide step-by-step instructions and model the task live on the interactive whiteboard for visual learners.
3. Independent Practice (25 mins): Hand out worksheets with step-by-step coding tasks. Allow students to replicate these tasks independently on their devices. Circulate the room to assist and provide prompt feedback.
4. Collaborative Activity (15 mins): Pair students and give them a collaborative challenge, such as creating a simple story animation using coding blocks. Encourage discussion, peer teaching, and sharing of ideas to foster a collaborative learning environment.
End Activities (10% of time):
1. Review (5 mins): Gather the class together and review key concepts, such as defining an algorithm, explaining the basics of sequence, and discussing common commands used in the lesson.
2. Reflection (5 mins): Conduct a brief discussion where students share what they found easy or challenging, and what aspects they enjoyed. This helps reinforce learning and offers insights into student experiences.
Assessment and Checks for Understanding:
1. Observe students during guided and independent practice, providing real-time feedback.
2. Collect and review worksheets to assess accuracy and comprehension of coding tasks.
3. Conduct quick, informal quizzes with flashcards to reinforce vocabulary.
4. Use exit tickets where students jot down one thing they learned and one question they have, to gauge understanding and areas needing clarification.
Differentiation Strategies:
1. For Struggling Students: Provide additional guided support, offer simplified tasks, and pair them with more proficient peers for collaborative activities.
2. For Advanced Students: Provide extension tasks that involve more complex algorithms or introduce additional commands and loops.
3. For Diverse Learners: Utilize a variety of visual aids, hands-on activities, and adaptable tasks to cater to different learning styles and abilities.
Teaching Notes:
– Ensure Scratch programming software is preloaded and all devices are functioning properly before class begins.
– Be attentive to the pace of the lesson, adjusting as necessary based on student engagement and understanding.
– Foster a positive and collaborative classroom environment, emphasizing that making mistakes is a natural and valuable part of the learning process.
Cross-Curricular Links:
– Mathematics: Link the concept of sequencing in algorithms to number patterns and sequences.
– Language: Enhance vocabulary development through learning and using new terms related to coding.
– Life Skills: Promote teamwork and problem-solving skills through collaborative activities.
Indigenous Knowledge Integration:
– Discuss how traditional African stories and oral instructions can be seen as forms of algorithms—sequential steps used to tell stories and perform tasks.
Practical Considerations:
– Implement safety measures during practical activities, ensuring students handle devices carefully.
– Manage group sizes effectively to ensure all students are actively engaged and supported.
Overall Enhancement:
– Incorporate creative storytelling within coding tasks to make learning more engaging.
– Add ‘Teaching Tips’ to encourage interactive questioning, foster critical thinking, and ensure active participation.
This refined lesson plan ensures a structured, engaging, and CAPS-aligned approach to teaching Grade 3 students the basics of algorithms and coding.
