Grade R Coding and Robotics Lesson Plan: Developing and Executing Algorithms

Materials Needed:

  • Flashcards with different steps (e.g., move forward, turn left, turn right)
  • Grid mats or floor mats with a simple grid pattern
  • Toy robots or simple programmable tools (like Bee-Bots or similar)
  • Coloured tape for marking paths on the floor
  • Whiteboard and markers
  • Printable worksheets with pre-designed grids and tasks
  • Stickers or tokens for rewards

Learning Objectives:

By the end of this lesson, students should be able to:
1. Understand what an algorithm is.
2. Create simple sequences of steps to perform a task.
3. Translate their sequence of steps into actions for a robot or model.
4. Debug sequences to correct errors.

Vocabulary:

  1. Algorithm – A list of steps to complete a task.
  2. Sequence – The order in which steps are taken.
  3. Forward – Moving in a straight direction.
  4. Turn Left – Changing direction to the left.
  5. Turn Right – Changing direction to the right.

Previous Learning:

Students have previously explored basic commands like “go”, “stop”, and “turn” through interactive games and stories. They are familiar with following and giving simple instructions.

Anticipated Challenges and Solutions:

  • Understanding Sequence Order: Some students may struggle with placing steps in the correct order. Solution: Use physical manipulatives like cards they can move around to visualize the sequence.
  • Debugging Errors: Students may find it hard to identify where they went wrong in their sequence. Solution: Encourage peer observation and suggestions to foster collaborative problem-solving skills.

Beginning Activities (4 minutes):

  1. Introduction (2 minutes):
  2. Briefly explain the concept of an algorithm in simple terms, using an everyday example (e.g., steps for brushing teeth).

  3. State the lesson objectives clearly.

  4. Activate Prior Knowledge (2 minutes):

  5. Ask students to recall a simple routine they follow and break it into steps (e.g., preparing for school).

Middle Activities (32 minutes):

  1. Direct Instruction (5 minutes):

  2. Demonstrate how to create a simple algorithm using a grid mat and a toy robot. Explain each step and highlight the importance of sequence.

  3. Guided Practice (12 minutes):

  4. Divide students into small groups. Give each group a set of flashcards with steps and a grid mat.
  5. Provide a task (e.g., guide the robot to reach a target on the grid).

  6. Walk around and assist groups, ensuring they discuss and agree on the sequence before executing it.

  7. Independent Practice (15 minutes):

  8. Hand out individual worksheets with simple grid tasks.
  9. Ask students to draw their sequence of steps first and then execute the algorithm using a toy robot on the floor grid or their desktop grid mat.
  10. Encourage students to debug and adjust their sequences if the robot does not reach the target correctly.

End Activities (4 minutes):

  1. Consolidation (3 minutes):

  2. Gather students and ask a few groups to share their algorithms and demonstrate with the toy robot.

  3. Exit Ticket (1 minute):

  4. Ask students to draw one step they found most challenging on a small piece of paper and place it in the exit ticket box.

Assessment and Checks for Understanding:

  • Observe group discussions and individual student engagement during guided and independent practice activities.
  • Review worksheets and exit tickets to assess understanding.
  • Use questioning during the demonstration to gauge comprehension and correct misconceptions.

Differentiation Strategies for Diverse Learners:

  • For students who need more support, provide additional visual aids and one-on-one assistance.
  • For advanced learners, introduce more complex tasks or encourage them to create their own unique grid challenges for peers.

Teaching Notes:

  • Emphasise the importance of the correct order in sequences.
  • Encourage collaboration and peer learning to strengthen understanding.
  • Be patient and give positive feedback to build confidence.
  • Use accessible mats and manipulatives to ensure all students, including those with motor skills challenges, can participate fully.

This lesson plan provides an engaging and interactive way for young learners to grasp the fundamental concepts of algorithms and sequences, which are critical building blocks in coding and robotics.
