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.

In this lesson, students will explore the “Testing Random Numbers” program to learn how to generate random numbers and use if-statements to make comparisons. Then, they will create a “Roll the Dice Game” to learn how to work conditionals and random numbers. At the end, students will create a simple program applying their knowledge of randomization and conditional control structures. 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.

In this lesson, students will implement Python programs that use “while” loops and logical operations as they consider how they might make their programs more interactive and control the flow of commands in their programs. They’ll read and modify examples, explore the new concepts through paired programming, and complete a short mini-project where they will demonstrate their new skills.

 This activity will allow students to compare Brute Force and Divide and Conquer sorting algorithms.This activity will show the sorting process of a Brute Force algorithm and a Divide and Conquer algorithm that is used by a computer when sorting data.

This activity will show the sorting process using the Bubble Sort Brute Force algorithm that is used by a computer when sorting data without using a computer.

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.

This activity allows for students to Identify the quantitative and qualitative benefits of going to collegeUnderstand common costs associated with collegeExplain the difference between sticker price and net price

In this activity, students will explore computational sequencing (the process of putting specific instructions to be executed by a computer in order) by engaging with recipes. Students will think through how a computer might interpret instructions, create instruction sets based on these insights, and share favorite recipes as they try to arrange instructions in a format that a computer might understand.

In this lesson, students will learn about using binary encoding to represent numbers and text. They’ll use several different encoding techniques, and then develop and test their own protocol for encoding other kinds of information into binary.

In this activity, students will write code that includes semantic HTML elements, and explore how semantic HTML helps make HTML easier to read, and increases the accessibility of websites for people who use screen readers and other assistive technologies.

This resource has a YouTube video link and a website link on how the German Enigma Machine worked to encrypt messages during World War II.

This is a short activity designed to help students understand more about the iterative process and how to develop algorithms that help define and implement that process.

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.
