Computer Science
Grade 3 · US Curriculum Standards
Third grade computer science introduces decisions. Students combine sequence, loops and conditionals so a program can respond differently depending on what happens, and learn to break a task into smaller parts before building it.
They begin working with data (entering it into a spreadsheet, sorting it and making a chart to answer a question) and learn how a search engine finds results and why some sources are more trustworthy than others.
