Students rotate through three classroom stations and identify similarities and differences between machines with and without memory, such as typewriters and computers, and illustrate how machines with memory fit into their world.

In this machine representation of a number worksheet, learners explore definitions such as floating-point, round-off error, binary representation of a number, mantissa, and sign bit. They identify significant digits and determine how...

Students locate transistor devices in school. They explain the importance of transistors.

Students explore the concept of fractions, decimals, and percents.  In this number sense lesson, students use a worksheet to guide them through the exploration of the relationship between fractions, decimals, and percents. ...

This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and...

The process of converting between different number bases is actually fairly simple, but the thinking behind it can seem a bit confusing at first. And while the topic of different bases may seem somewhat pointless to you, the rise of...

An overview of the binary number systems in computer science.

Bits and binary data are explained.

Create programs with sequencing, loops, and events. Translate your initials into binary, investigate different problem-solving techniques, and learn how to respond to cyberbullying. At the end of the course, create your very own game or...

Check your understanding of number precision, overflow errors, and roundoff errors in computer programs.
