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 counting

These 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 dots

This 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 octal

In this simple worksheet, the student counts from 0 to 77 in octal (which corresponds to 0 to 63 in decimal).

Counting in binary

In this worksheet, the student counts from 0 to 111111 in binary (which corresponds to 0 to 63 in decimal).

Converting from binary to decimal

Worksheet showing how to convert from binary to decimal.

Converting from decimal to binary

Worksheet showing how to convert from decimal to binary.

Converting from binary to octal

Worksheet showing how to convert from binary to octal.

Converting from binary to hexadecimal

Worksheet showing how to convert from binary to hexadecimal.

Binary magic trick

A 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 Hexadecimal

In this worksheet, the student counts from 0 to 63 (but in hexadecimal, so it's really 0 to 4F).

Number cards (Binary, Octal, Decimal, Hexadecimal)

Playing-card sized cards that can be used to compare the different number systems.

Bitmaps (Binary, Hexadecimal)

Worksheets to encode black and white images as binary numbers.

Boolean Logic

(Worksheets AND TeacherNotes) for (Teaching OR Practice OR Homework)

Object Properties

Assign boolean properties to objects and then use those properties to select a subset of the objects.

Boolean Logic : Nethack

Review of basic boolean operations using examples from Nethack.

General Computer Science

Materials on general computer science topics.

How Computers Work

An activity for 3 students to act out the various parts of a computer: CPU, ALU/Memory and Display.

How the Internet Works

An activity for a group of students to act out the various parts of the internet: websites, routers, nameservers, ISPs and home computers.

Miscellaneous
