# 4.2 Input, Output & Variables Coding Practice (ECS+Python)

(View Complete Item Description)

"In this lesson, students will read and trace a “Hello World'' Python program to learn how to display simple output. Then, they will create an “Addition Calculator” to learn how to work with variables and arithmetic operators. At the end, students will modify and complete partially-written Python programs, applying their knowledge of variables and arithmetic operations. 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.

# 4.6 Loops & Logic Coding Practice (ECS+Python)

(View Complete Item Description)

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 lesson is part of CodeVA's ECS+Python lesson set, providing alternative units for the Exploring Computer Science curriculum covering basic Python coding concepts.

# ECS 1.1-2: Computing Concepts

(View Complete Item Description)

Students will explore how computers are embedded in the activities of their ‘every day’ through keeping a technology journal and sharing their timeline with a group of students or the class. Through this activity, students learn to find examples of their own definition of computing before engaging in the class discussion about how we might choose to classify computers by their characteristics. Students end the activity by designing a technology that solves a common/current problem in their own routine (“I wish there was a computer that could help me…..”). Through this examination, students will learn that computers can do many things to help humans solve problems on micro and macro levels.A supplementary lesson plan for ECS Unit 1, days 1-2 by Perry Shank

# ECS 1.11-1.14: Data Representations

(View Complete Item Description)

In this project, students will create artistic data representations, expressive artifacts based on data sets. Before engaging in their own projects, students will briefly research and discuss data-based art making in history and in contemporary times. Then, students will use the remaining 3 instructional days to create their art. The resources below provide support for two kinds of representational projects—data-based music, and data-based visual art on a grid (similar to the weaving art discussed in ECS 1.11-14).

# ECS 1.15-16 Recipes

(View Complete Item Description)

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.

# ECS 1.10: Data Scramble

(View Complete Item Description)

In this activity, students will explore the idea of “data” and how it provides a lens through which to view different aspects of human experience. Students will interrogate the affordances and constraints of data as a form of representation and speculate about the effects data can have on human perception and behavior by fitting data into different schemata, developing their own data schemata, and comparing the data schemata of different institutions in their lives with the schemata they develop to represent themselves.

# ECS 3.12-13 Website Design Ideation

(View Complete Item Description)

In this activity, students will develop an idea for a new website they will create to practice their new web accessibility knowledge & development skills. Students will assess what sorts of websites they might create to serve as a platform for information sharing, serving the needs of a particular user group in their school or community, or curating resources around a particular topic.

# ECS 3.17-19 File Size & Internet Speed

(View Complete Item Description)

In this lesson, students will explore the relationship between website file size, request volume, and internet speed. They will then unpack how website design impacts accessibility for web users with slow or unreliable internet, outdated computers, or other constraints that lead to information access issues.
