OverviewStudents learn the basics of conditionals through an unplugged activity using the sticky notes and plastic baggies from the Variables Explore lesson. Flowcharts are introduced as a way to understand how computers make decisions using Boolean expressions. GoalsStudents will be able to:Use appropriate vocabulary to describe Boolean expressions and conditional statementsEvaluate expressions that include Boolean values, comparison operators, and logical operatorsTrace simple programs that use Boolean expressions and conditional statementsPurposeThe warm up activity is designed to provide context for the Conditionals progression. The subsequent activity provides students a physical mental model they will be able to use when they start programming with conditionals in the subsequent lessons.ResourcesCS Principles: Conditionals - Part 1 Boolean Expressions (Video)Code.org CSP Unit 4 - Variables, Conditionals, and Functions (Presentation Slides)Getting Started (5 minutes)Discuss: Imagi...
