Boolean logic worksheets

These sheets from cse4k12 are excellent activities to help students understand Boolean logic and Boolean conditions. The sheets present students with a series of 2D shapes with different properties. Students must identify and use different Boolean conditions (e.g. isTriangle, isShaded) to select particular groups of shapes.

PDF and SVG versions of the documents are supplied, and they are licenced under CC-SA, so you can make alterations if you wish (e.g. adding colour)

The site also has several related worksheets, such as Boolean logic to Venn diagram handouts and truth tables for logic gates.
