Bits and Integers

Compression, the process computers use to store information, is the focus of a resource that presents two different stories that describe the concept of compression by eliminating repeated letters and replacing them with a pointer. The...

How do you modify digital pictures? In this lab learners write methods that modify digital pictures. They how to traverse a two-dimensional array of integers or objects, and are introduced to nested loops, binary numbers, interfaces, and...

Binary graphing ... bit by bit. Pairs work together to develop a protocol in order to send the points of a graph. One partner sends the points and the other receives them and tries to recreate the graph. The pupils use the rubric to...

Imagine drawing with zeros and ones. The third lesson in a unit of 15 introduces the class to creating black and white images. Pairs get together to create an encoding scheme in order to make these images. They move on to a using a...

A bite of bits. The first activity in a unit of 15 introduces the class to the byte. Pupils learn about other standard units for measuring file sizes, develop an understanding of relative sizes and the kind of units used to measure...

Show your class how to develop a protocol to solve a problem. Pupils then continue with working with binary messages but refine a protocol to assist with the distinction of individual bits by including a bit rate. Finally, the pairs use...

All you need is a zero and a one. Build pupils' understanding of binary values and number systems to gain familiarity with binary numbers. Using a hands-on activity and technology, scholars learn how the binary system works and its place...

Ah, the numerous number of numbers. Individuals research different ways of encoding numbers. After conducting their initial research, they find classmates who have researched a different article and the pair share information. The lesson...

Encoding What I did Last Summer. Class members develop a way to encode a personal experience using a top-down approach to determine components and sub-components of their experience They then pick one portion of the experience and go...

Investigate how public key cryptography works. Scholars continue their study of one-way functions and asymmetric keys and apply this information to public key cryptography. They use an app to explore public key cryptography and its...
