# Booleans ![micro:bit Combo Box](/static/courses/csintro/booleans/cover.jpeg) This lesson introduces the use of the boolean data type to control the flow of a program, keep track of state, and to include or exclude certain conditions. ## Lesson objectives Students will... * Understand what booleans and boolean operators are, and why and when to use them in a program. * Learn how to create a boolean, set the boolean to an initial value, and change the value of the boolean within a micro:bit program. * Learn how to use the random true or false block. * Apply the above knowledge and skills to create a unique program that uses booleans and boolean operators as an integral part of the program. ## Lesson structure * Introduction: Booleans in daily life * Unplugged Activity: Two Heads are Better Than One * micro:bit Activity: Double Coin Flipper * Project: Boolean * Assessment: Rubric * Standards: Listed ## Lesson plan 1.
