Grade 2 Coding and Robotics Lesson Plan: Coding

Lesson Plan Title:
Grade 2 Coding and Robotics Lesson Plan: Recognise and Interpret Patterns in Symbolic Sets of Data or Visualisations

Materials Needed:
– Computer or tablets with age-appropriate coding software (such as Scratch Jr)
– Projector and screen or interactive whiteboard
– Printed worksheets with visual patterns
– Coloured markers or crayons
– Flashcards with symbolic patterns
– Interactive coding app (optional)

Learning Objectives:
– Students will be able to recognise and identify patterns in symbolic sets of data.
– Students will interpret simple visualisations and understand the concept of pattern repetition.
– Students will apply their understanding of patterns in a basic coding activity.

1. Pattern – A repeated or regular arrangement of elements.
2. Symbol – A mark or character used as a representation of something else.
3. Data – Information, especially facts or numbers, collected to be examined and used.
4. Visualisation – A visual representation of data.
5. Repetition – The action of repeating something that has already been done or said.

Previous Learning:
Students have been introduced to basic concepts of coding and robotics, including understanding commands and sequences. They have also worked with simple visual patterns in their mathematics classes.

Anticipated Challenges and Solutions:
Challenge: Some students may struggle with identifying patterns.
Solution: Use clear, simple examples and provide plenty of guided practice.
Challenge: Students may find the transition from visual patterns to coding unfamiliar.
Solution: Bridge the learning with step-by-step instructions and visual aids.

Beginning Activities (10% of lesson time):
– Welcome and introductions (2 minutes)
– Briefly review the previous lesson on simple sequences. Use flashcards to refresh their memory (2 minutes).
– Introduce today’s lesson by explaining what patterns are and showing a few examples using slides or the interactive whiteboard (4 minutes).

Middle Activities (80% of lesson time):
1. Direct Instruction (10 minutes):
– Explain how patterns are found in coding and robotics.
– Show a simple visualisation of patterns on the screen and discuss repetition using everyday examples (clapping pattern, walking steps, etc.).

  1. Guided Practice (15 minutes):
  2. Distribute printed worksheets with incomplete patterns.
  3. Work through one or two patterns as a class, guiding students to identify and complete them.
  4. Use the projector or interactive whiteboard to illustrate how these patterns can look in a simple code.

  5. Independent Practice (15 minutes):

  6. Let students work independently or in pairs to complete the pattern worksheets.
  7. Circulate the room to offer assistance and observe student participation.

  8. Application to Coding (15 minutes):

  9. Transition to using computers or tablets.
  10. Demonstrate a simple coding activity in Scratch Jr. where students have to recognise and create patterns within the code (e.g., making a character move in a pattern).
  11. Allow students to try their coding pattern activity, offering guidance as needed.

End Activities (10% of lesson time):
Review and Exit Ticket (6 minutes):
– Summarise lesson points and ask a few students to share the patterns they found and created in their coding exercise.
– Hand out a quick exit ticket activity where students draw or write a simple pattern and describe it.
Closure (2 minutes):
– Praise students for their effort and explain what they will learn in the next lesson.

Assessment and Checks for Understanding:
– Observation of students during guided and independent practice.
– Completion and accuracy of pattern worksheets.
– Coding activity performance and final patterns created.
– Exit ticket responses to gauge individual understanding.

Differentiation Strategies for Diverse Learners:
For Struggling Students: Provide extra one-on-one or small group coaching, use simpler patterns, and allow more time for tasks.
For Advanced Students: Offer more complex patterns to complete and allow them to create their own patterns in coding, adding more steps or characters.

Teaching Notes:
– Emphasise the concept of repetition in patterns as it is crucial for understanding coding sequences.
– Encourage students to verbalise their thought process when identifying and creating patterns to solidify their understanding.
– Ensure that students with disabilities have access to adaptive technology or modified worksheets as needed.

Accessibility Considerations:
– Use high-contrast visuals and large print materials for students with visual impairments.
– Provide hands-on manipulatives for kinesthetic learners.
– Ensure that digital tools and software are accessible to all students, including those with physical disabilities.
