Grade 3 Coding and Robotics – Introduction to Pattern Recognition

Lesson Plan Title: Grade 3 Coding and Robotics – Introduction to Pattern Recognition


2. Materials Needed

  • Interactive whiteboard or projector
  • Printed pattern cards (simple sequences)
  • Laptops or tablets with coding software (e.g., Scratch Jr)
  • Graph paper
  • Markers or crayons
  • Pattern blocks or manipulatives

3. Learning Objectives

  • Understand the concept of patterns and their importance in coding and robotics.
  • Identify and extend basic patterns using different mediums (shapes, colors, numbers).
  • Recognize and create patterns in simple codes.

4. Vocabulary

  • Pattern: A repeated decorative design or sequence.
  • Sequence: A particular order in which related events, movements, or items follow each other.
  • Algorithm: A process or set of rules followed in problem-solving or calculations.
  • Repetition: The action of repeating something.

5. Previous Learning

Students should be familiar with basic shapes, colors, and numbers. They should also have basic counting and sequencing skills.


6. Anticipated Challenges and Solutions

  • Challenge: Understanding the concept of patterns.
    • Solution: Use concrete examples and manipulatives to visually and physically demonstrate patterns.
  • Challenge: Varying levels of familiarity with technology.
    • Solution: Pair students with different skill levels to encourage peer learning and provide additional support as needed.

7. Beginning Activities (10% of time)

  • Activity: Introduction to Patterns
    • Time: 10 minutes
    • Steps:
    1. Discuss patterns in everyday life (e.g., zebra stripes, days of the week).
    2. Show visual examples of patterns on the board.
    3. Ask students to share any patterns they have noticed in their daily lives.

8. Middle Activities (80% of time)

  1. Activity: Pattern Cards
    • Time: 15 minutes
    • Steps:
      1. Distribute printed pattern cards.
      2. Instruct students to identify and extend the patterns on their cards.
      3. Discuss their observations as a class.
  2. Activity: Creating Patterns with Manipulatives
    • Time: 15 minutes
    • Steps:
      1. Provide pattern blocks or manipulatives.
      2. Ask students to create their own patterns using the blocks.
      3. Have students walk around to observe and discuss each other’s creations.
  3. Activity: Coding with Scratch Jr
    • Time: 40 minutes
    • Steps:
      1. Introduce Scratch Jr and demonstrate how to create a simple sequence using the app.
      2. Guide students to create a basic repeating pattern using Scratch Jr (e.g., making a character move in a repeating sequence).
      3. Allow students to experiment and create their own patterns in the software.
      4. Circulate to offer assistance and ensure understanding.

9. End Activities (10% of time)

  • Activity: Review and Reflection
    • Time: 10 minutes
    • Steps:
    1. Gather students in a circle.
    2. Ask volunteers to share what they created and learned about patterns.
    3. Summarize key points from the lesson.

10. Assessment and Checks for Understanding

  • Observe students during activities to check for understanding.
  • Review completed pattern cards and manipulative patterns.
  • Assess student-created sequences in Scratch Jr.
  • Use questioning throughout the lesson to gauge comprehension (e.g., “What comes next in this pattern? Why?”).

11. Differentiation Strategies

  • For Struggling Students:
    • Provide additional manipulatives and simpler patterns.
    • Pair with a more advanced peer for collaborative learning.
  • For Advanced Students:
    • Introduce more complex patterns.
    • Challenge them to create multiple sequences and identify algorithmic patterns in Scratch Jr.
  • For Students with Disabilities:
    • Adapt materials (e.g., larger pattern blocks, high-contrast cards).
    • Allow more time for activities and provide one-on-one assistance.

12. Teaching Notes

  • Ensure laptops/tablets are preloaded with Scratch Jr and charged.
  • Prepare pattern cards and manipulatives in advance.
  • Allow flexibility in the lesson plan to accommodate various learning paces.
  • Encourage a positive and inclusive environment where all students feel comfortable sharing their ideas.
