A collection of handouts, worksheets and other documents to help teach Computer Science and Engineering concepts.
These materials primarily target middle-school students (6th - 8th grade), but most can be used without modification for younger or older students.
Number Systems
Materials for teaching binary, octal, decimal and hexadecimal.

Octal countingThese worksheets introduce the students to a non-decimal number system (in this case, octal) by having them count objects in both octal and decimal. |
Octal dotsThis worksheet has the students take an octal number and draw that many dots. After finishing, they count the number of dots in decimal to check their answer. |
Counting in octalIn this simple worksheet, the student counts from 0 to 77 in octal (which corresponds to 0 to 63 in decimal). |
Counting in binaryIn this worksheet, the student counts from 0 to 111111 in binary (which corresponds to 0 to 63 in decimal). |

Binary magic trickA set of 6 cards for a simple magic trick where you guess the secret number chosen by a student. Understanding the trick requires knowledge of binary. |
Perfect Card Shuffling (Binary)Knowledge of binary numbers and the ability to perform 'perfect shuffles' can allow you to shuffle the top card down to any desired position in the deck. |
Crossbin puzzles (Binary, Hexadecimal)These are "crossword" puzzles where the clues are in hexadecimal and the answers are binary numbers. When the puzzle is complete, the grid forms a simple black & white image. |
Counting in HexadecimalIn this worksheet, the student counts from 0 to 63 (but in hexadecimal, so it's really 0 to 4F). |
