Optional Review

Welcome to CodeHop!

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

Introduction to ScratchJr

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

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

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.

Practicing Responsible Technology Use

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

Coding Card Game: Conditionals

Students will be able to work together to create a sequence of instructions with conditionals to move Scout through a maze.

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

Debugging: Events and Sequences

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

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

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.

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.

Culmination Projects

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.

Maze Game Project

Students will create and explore multiple ways to program an interactive game using events, messages, loops and sequences, as well as revise their program based on feedback.

Digital Literacy

Password Protectors

Students will understand the importance of usernames and passwords and demonstrate strategies to keep login information safe.

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.

Exploring Spreadsheets

Students will use spreadsheet software to review and present data on class pets and favorite colors.

Choice Research

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

Data Patterns and Predictions

Students will be able to identify and describe patterns and trends in data visualizations, then create a program using events to communicate patterns, trends and predictions from a given data set.

Advanced Data and Programming

Students will be able to develop an investigative question, collect data using a survey, and create a program to present the data visually.

Interdisciplinary Computer Science

Story Problems: Add and Subtract within 100

Students will be able to create a program to model a math story problem.

Place Value: Ones, Tens, and Hundreds

Students will be able to connect a digit’s place in a number to its value and create an interactive program that uses events.

Identify Shapes by Attributes

Students will be able to create a program to draw and identify shapes with specified attributes.

Greater Than and Less Than: Three-Digit Numbers

Students will be able to use events to create a program that tells if a number is greater than, less than, or equal to another number.

Designing Solutions from Nature

Students will be able to create a program using events that show how humans survive in their environments by mimicking plants and animals.

Properties of Matter

Students will be able to use conditionals to program a robot to make accurate decisions and to group different types of matter according to their properties.

Seed Dispersal

Students will create a program using message events and loops to model how an animal can help disperse seeds.

Preventing Erosion

Students will create a program to compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.

Punctuation: Write a Great Sentence!

Students will be able to create sequences with loops to write sentences with correct punctuation and spacing.

Original Story Animations - Fiction Story

Students will be able to develop an original story and create a program to animate a story.

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.
