In this activity, students will use a model of a computer, taking the form of a sort of board game, to explore writing programs that include input, output, variables, and arithmetic. Students will read, write, and debug pseudocode as they work on solving simple programming problems using manipulatives. This lesson is part of the ECS+Python lesson set, providing supplemental Python curricular material for the Exploring Computer Science curriculum.

In this project, students create a program that performs calculations on input values to produce formatted output. Students will choose a project to create from a list of three options, or generate their own option that meets the activity requirements. This lesson is part of CodeVA's ECS+Python lesson set, providing alternative units for the Exploring Computer Science curriculum covering basic Python coding concepts.

This lesson is designed to teach students basic encryption using the Caesar cipher method. This is a simple letter shift cipher that takes a plaintext message and encrypts it into cipher text by shifting each letter of the message by a value between 1 and 25 (1 less than the total number of letters in the English alphabet). This technique was used by Julius Caesar to encrypt messages by shifting each letter of the message by 3 letters. The message would be decrypted by taking each letter and shifting back 3 letters to reveal the plaintext message.

Students will be able to describe how “intelligence” differs between machines and humans.

Students will be able to describe computer hardware and choose appropriate components for users.

 Explore the four main phases of the problem-solving process. Analyze a problem and use the steps in the problem-solving process to solve a problem.

 Hyperlinks help us to navigate easily to other websites and find information more quickly.

Students will learn to write lines of code as conditional statements and they will learn to write equations of circles and transformations as lines of code to accomplish a goal. At the end of this lesson, students will have created an animated greeting card.

This activity will allow students to create a simple bank account program using the Java programming language. This activity could also be edited to use any programming language.

This lesson introduces 9-12 grade students to the tuple data type using Python. Students will learn what tuples are and how to create and use them.

What is Random? Through this project, students will discover what makes an outcome random. Emphasis will be placed on the difference between deterministic and nondeterministic outcomes.  The project starts out with a discovery activity where students will see the difference between creating data with a coin toss where they just make up the data and creating data through actually tossing a coin.Students will end the project by studying pseudorandom number generators, specifically the Middle Squared Algorithm. They will even create a program that uses this algorithm.  Enjoy!
