Introduction to Code

Unit #1

Duration

10 minutes

Class Size

10 students

Subject

Python Basics

Standards Alignment

• Common Core State Standards (CCSS)

  • CCSS.Math.Content.8.F.A.1: Understand that a function is a rule that assigns to each input exactly one output.

• Next Generation Science Standards (NGSS)

  • MS-ETS1-1: Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution.

Learning Targets

• Students will understand basic programming concepts including variables, data types, and simple arithmetic operations.
• Students will create a simple program that demonstrates these concepts using Python.

Materials Needed

• Laptops or tablets with Python installed (or access to an online Python interpreter)
• Whiteboard and markers
• Printed handouts with example code

Differentiated Instruction

• For advanced students: Introduce the concept of functions for optional exploration.
• For struggling students: Provide a one-on-one support option and additional resources with visual aids to reinforce understanding.

Lesson Outline

1. Introduction (2 minutes)

• Objective: Briefly introduce Python as a programming language.
• Method:
  • Engage students with a rhetorical question: "Have you ever wondered how your favorite apps were created?"
  • Explain that Python is a powerful yet beginner-friendly language used in various tech fields.

2. Basic Concepts (4 minutes)

• Objective: Teach the basic concepts such as variables, data types, and arithmetic operations.
• Method:
  • Variables: Introduce the concept of variables using a relatable analogy (e.g., boxes that store information).
    • Example: "Think of a variable like a box where you store your favorite number."
  • Data Types: Explain the difference between integers, floats, and strings.
    • Use a whiteboard to illustrate:
      • Integer: 5
      • Float: 5.0
      • String: "Hello"
  • Arithmetic Operations: Demonstrate simple operations (+, -, *, /).
    • Write example codes on the whiteboard:

      x = 5
      y = 3
      print(x + y)
      

3. Hands-On Activity (3 minutes)

• Objective: Allow students to apply what they learned by writing a basic program.
• Method:
  • Instruct each student to open Python and write a program that assigns values to two variables and prints their sum.
  • Provide support as students work, answering questions and encouraging peer collaboration.

4. Wrap-Up and Reflection (1 minute)

• Objective: Solidify understanding and encourage feedback.
• Method:
  • Ask students to share their outputs and discuss how changing variable values affects the results.
  • Encourage students to reflect: "What other operations would you like to explore in Python?"

5. Homework (optional)

• Students can extend their learning by attempting to create a simple program that uses inputs to ask for their name and age, and then prints a message back to them.

Assessment

• Observe students during the hands-on activity, providing feedback and noting who requires additional support.
• Collect outputs from their programs to assess if they understand the concepts taught.

Inclusion Practices

• Use clear, concise language and visual aids to support English Language Learners (ELL).
• Arrange students in pairs or small groups to facilitate peer support and increase engagement.
