11th Grade Logic Puzzle Worksheets

High school logic covers formal reasoning: conditional statements, valid and invalid arguments, common fallacies, ciphers and probability. Puzzles and practice sheets sharpen the analytical thinking used in geometry proofs, computer science, debate and standardized tests, and make careful reasoning a habit. These eleventh grade logic worksheets are free printable PDFs for review and test practice, many with answer keys for grown-ups.
