Free 10th Grade Variables Practice Lesson Plan (Computer Science Principles)

Topic: Debug and Write Programs that Use Variables and Expressions

Objectives & Outcomes:

• Understand how to debug and write programs that use variables and expressions.
• Understand how to identify and fix syntax errors in programs that use variables and expressions.

Materials

• Computer with a text editor or IDE
• Sample code for the class to work with

Warm-up

• Ask students to name some things that variables can be used to represent. Examples could include numbers, words, or strings of text.
• Have students brainstorm a list of different types of expressions that can be used in programs. Examples could include additions, subtractions, or comparisons.
• As a class, create a list of the different types of variables and expressions that will be covered in the class

Direct Instruction

• Introduce the concept of variables and expressions in programming. Explain how variables are used to store information in programs, and how expressions are used to perform actions on that information.
• Provide a brief overview of the different types of variables and expressions that will be covered in the class. Emphasize the importance of debugging and testing variables and expressions to ensure that they are working properly.

Guided Practice

• Provide the students with a set of sample code and a set of problems to solve using the code. The code should include examples of variables and expressions being used correctly.
• Have the students work through the problems with guidance from the instructor, analyzing the code and the problems to ensure that they are correctly solving them.
• As the students are working through the problems, provide feedback and assistance as needed.

Independent Practice

• Have the students work on a project-based independent practice, where they use variables and expressions to write a program to solve a practical problem. The students can choose their own problem to solve, or the instructor can provide a problem for them to solve.
• Have the students use the sample code and the support provided to them to write their program, using variables and expressions correctly.
• Provide support and guidance as needed to help the students complete their programs.

Closure

• Review the key concepts of variables and expressions, and have the students give examples of their own.
• Ask the students to reflect on their learning and what they found most challenging about the lesson.

Assessment

• Observe the students during the guided practice and independent practice activities.
• Collect and review the students' completed worksheets.
• Administer a quiz to assess the students' understanding of variables and expressions.
