Optional Review

Welcome to CodeHop!

Students will learn how to log in and use the CodeHopJr Playground. This short introductory lesson can be used on its own or right before a full lesson.

Introduction to Programming

Students will be able to navigate the programming interface to create a scene with characters.

Events

Students will be able to explain what an event is in programming and use multiple event blocks in a program.

Introduction to Repeat Loops

Students will be able to use repeat loops to run a section of code multiple times.

Forever Loop Dance Party

Students will be able to create a sequence using a “repeat forever” loop to make characters repeat actions.

Introduction to Message Events

Students will be able to program a relay race that uses messages to cause characters to interact.

Getting Started

Computational Thinking: School Day Routines

Students will be able to use computational thinking concepts to identify patterns, break down tasks, sequence steps, and simplify processes in their school day routines.

Sequences & Events

Introduction to the Grid

Students will be able to use the grid feature to move characters to a specific location on the stage.

Tap-a-Mole Game

Create an interactive game using events.

Debugging: Events and Sequences

Students will be able to find and fix errors in provided code.

Loops

Loops: Follow the Path

Students will be able to identify patterns, and create a program using loops.

Making a Timer

Students will be able to use loops, wait blocks, and turn blocks to create and compare two timers with different speeds.

Two-Step Dance & Feedback

Students will be able to create a program and revise it based on peer feedback and give attribution to a peer who helped improve their work.

Algorithms: Connecting a Path

Students will be able to create and adjust simple algorithms to move characters based on their size, shape, and starting position.

Message Events

Message Events: Scout Plays in the Forest

Students will be able to use message events to control the flow of a program.

Programming a Cycle

Students will be able to use message events to model a cycle.

Pages: Scout's Travels

Students will be able to use messages to help Scout travel between pages in a program.

Debugging: Message Events and Loops

Students will be able to find and fix (debug) message event and loop errors in the provided code.

Exploring the Design Process

Students will be able to use the design process to plan, create, and improve a program with loops that models a solution to a simple real-world problem.

Culmination Projects

Code Block Review

Students will be able to use a variety of coding blocks in a program and explain their function within the program.

Racing Game

Students will be able to create an interactive racing game with events, loops, and messages.

Moving Targets Game

Create a moving target game using sequences, events, and pages.

Computing Systems

Computer Basics: Connections

Students will be able to learn what a computer is, how we use it, and what to do when it doesn’t work. They will also be able to identify input, output, hardware, and software, and explain how they work together.

Exploring Computer Networks

Students will be able to describe how networks connect devices to share information and model the sending and receiving of information using message blocks.

Safety & Responsibility

Responsible Digital Citizens

Students will be able to explain what it means to be a responsible digital citizen, including understanding digital footprints, discussing cyberbullying, and knowing how to report concerns.

Practicing Responsible Technology Use

Students will be able to demonstrate ways to use technology safely and responsibly.

Data & Analysis

Data Explorers

Students will develop an investigative question and collect data using a survey. Then, students will create a program to present their collected data visually.

Managing Data Storage and Files

Students will be able to recognize that computers store data as files and model how data is collected and stored.

Choice Research

Students will be able to collect and assess sources to answer a research question and communicate their findings visually.

Impacts of Computing

Careers in CS: Fashion-Retail

Students will be able to explain how coding helps create and improve fashion designs and will create a program to design and animate a fashion character.

Impacts of Computing: Changing World

Students will be able to identify examples of computing devices in their daily lives and use programming to explain how technology has changed the way people live, work, and play.

AI Exploration

How AI Helps Us

Students will be able to explain how AI assistants answer questions by observing a demonstration and describe how AI helps people by solving problems and changing jobs.

Machine Learning: AutoDraw

Students will be able to describe how AutoDraw uses AI and a classifier to recognize and suggest drawings.

Preparing for Next Year

From CodeHopJr to CodeHop Blocks

Students will be able to navigate the basic interface of the CodeHop editor to create a simple program.

From CodeHopJr to CodeHop Blocks: Part 2

Students will be able to create a CodeHop program that uses an event and a loop.

Variables: Keeping Score

Students will be able to create a program that simulates keeping score using a variable.
