Trixie the Elf needs helping searching for the perfect outfit for each day of the week. Learn how to use boolean expressions to narrow down exactly the right outfit in this Christmas Elf boolean logic activity.
Boolean logic sounds like a pretty complex concept, but it’s actually very easy to understand. Booleans are a type of data that has two values either true or false that can be used to evaluate logical questions.
Booleans are named after Philosopher and Mathematician George Boole, who first defined an algebraic system in the mid 19th century. Have you ever played the game Guess Who? Then you’ve used Boolean logic!
How are Booleans used in Programming?
Booleans are used to produce more effective search results by using Boolean functions to eliminate or provide search parameters for logical questions.
You start off with the idea that a statement is either true or false. It can’t be anything else. After your statement, you can form other statements that are true or false by combining the statements with a Boolean function such as AND and OR.

DRESS THE ELF BOOLEAN LOGIC ACTIVITY
This activity focuses on the comparison operators and boolean operators in selection statements.
== and != are comparison operators
AND and OR are boolean operators
== means “is equal to?” and != means “is not equal to?”
The outfit picked must meet both conditions in an AND statement and one condition of an OR statement.
Each comparison is a boolean and results in either a True or False answer. Use the selection and boolean statements to dress Trixie the Elf! There will be multiple answers for each day, so check your work to make sure that the final pieces fit the search parameters.
