UNITS - 8 (38 lessons)
This optional review module revisits foundational programming concepts from the prior year, including navigating the interface, using events, and applying repeat, forever, and message-triggered loops.
Students learn how computer hardware and software work together, then apply computational thinking to sequence and simplify their school day routines.
Students use the grid feature to precisely position characters, practice debugging sequence and event errors, design algorithms to connect paths, and explore how coding applies to fashion design careers.
Students use message events to control program flow and model cycles, combine messages with pages to move characters between scenes, and introduce variables to keep score in a game.
Students identify patterns and use loops to build programs like a maze-following animation and a timer, practice debugging loop and message errors, and create and revise an original animated story based on peer feedback.
Students apply the design process to build and revise culminating game projects, including a racing game, a moving-targets game, and a maze game, and conduct a data investigation to identify patterns and make predictions.
Students build digital literacy by researching topics of their choice, comparing software applications, exploring how technology has changed the world, practicing password safety and responsible digital citizenship, and modeling how networks and data storage work.
Students transition from CodeHopJr to the CodeHop block-based editor and practice sequencing conditional logic through unplugged maze card games in preparation for next year's course.
2nd grade students use the grid, message events, loops, and variables to build programs, practice debugging, giving feedback, and the design process, and complete projects including a racing game, a moving targets game, and a maze game. They also collect survey data and use it to make predictions, explore a fashion-retail career, research questions they choose, practice digital citizenship and password safety, explore how technology has changed the world, and learn how networks and file storage work.
Optional lessons at the end of the course introduce the programming blocks students will use in 3rd grade and beyond, and introduce conditionals through team card games.
The course includes 36 lessons, each about 45 minutes long, providing a full year of instruction when taught once a week. Every lesson is built in a ready-to-teach format, with step-by-step videos that walk students through the lesson. Lessons are designed to be teacher-led using an "I do, we do, you do" format, and a self-paced option is also available. Optional review lessons at the start of the course are not counted in the 36 lessons.
No. There are no prerequisites, and the course is designed to support all learners regardless of prior computer science experience. Optional review lessons at the start of the course help students who are new to CodeHop review events, loops, and message events before moving into 2nd grade content.
Maryland Computer Science: 2nd Grade is aligned to the Maryland K-12 Computer Science Standards. Lessons required to fully meet the standards are labeled in the course syllabus with the standards they address, and all Digital Literacy lessons are required because they cover essential non-programming computer science concepts.
