Free Algorithms Introduction Lesson Plan for 10th Grade Students

Topic: Algorithms Introduction

Objectives & Outcomes

Introduce algorithms to students and demonstrate their practical applications in solving problems

Materials

Handouts with examples of algorithms

Computers or tablets for students to write code and execute algorithms

Warm-up

Ask students to think of a problem they have faced in their lives.

Have them formulate a solution to the problem and explain how they would go about solving it.

Ask them if they have ever used a proven solution or a step-by-step procedure to solve a problem. If so, ask them to provide an example.

Direct Instruction

Explain that algorithms are step-by-step procedures for solving problems.

Introduce the concept of an algorithm by using a hands-on activity. For example, have students work in pairs to solve a simple problem using an algorithm. For example, have them use the algorithm for solving a multiplication problem to solve a multiplication problem. As they work, have them explain the steps of the algorithm and why each step is necessary.

If time permits, present additional examples of algorithms and have students work in pairs to solve the problems using the algorithms.

Guided Practice

Have students work in pairs to solve a set of problems using algorithms. For example, have them solve a series of multiplication problems using the algorithm for solving a multiplication problem. As they work, have them explain the steps of the algorithm and why each step is necessary.

If time permits, present additional examples of algorithms and have students work in pairs to solve the problems using the algorithms.

Independent Practice

Have students work on a project-based activity in which they must create their own algorithm for solving a problem. For example, have them create an algorithm for solving a quadratic equation or solving a system of linear equations. As they work, have them explain the steps of their algorithm and why each step is necessary.

Closure

Review the main points of the lesson: algorithms are step-by-step instructions for solving a problem, they can be expressed as -lists, flowcharts, or diagrams, and they can be implemented in -computer code.

Ask students to share any interesting or challenging aspects of the independent practice activity.

Assessment

Observe students during the guided practice and independent practice activities to assess their understanding of the concept of an algorithm and their ability to create and implement algorithms in -computer code.

Have students complete a short written reflection on their experience with creating and implementing algorithms during the independent practice activity.
