### What is Digital Media and Digital Communications?

Everywhere you look you’ll find something that is “digital.” Computers, smart phones, streaming movies, video game consoles, household appliances, cars and thousands of other gadgets use digital information. We use these items every day but few people understand what the term “digital” really means.

**What does the word “digital” mean?**

It comes from “digit,” one of ten symbols used to write numbers. Precisely speaking, the digits are 0, 1, 2, 3, 4 ,5, 6, 7, 8 and 9. But in talking about computers, “digital” refers to just the digits “0” and “1.” Digital machines store and communicate information as 0’s and 1’s.

### What is a Math Trail?

The math trail was first conceived as a way to help students become active learners by finding the math that exists in their communities.

There is no one “right way” to conduct a math trail. The basic activity is simple: students observe the environment outside the classroom, to discover examples of math concepts that they are studying. They then create problems for others to solve based on their observations.

### What is a Dimension?

##### By Beth Walker *Ph.D. Mathematics Education*

What do you know about space; not the final frontiers of cosmic explorers but our most immediate environment? We live in three-dimensional space, eat off two-dimensional tabletops, and drive or walk in one-dimension at a time. Like a riddle, we don’t create space, but often try to contain it. We assign space measures, but often don’t understand what those measures mean. In mathematics, the study of one-, two- and three-dimensional space is often referred to as geometry. What are dimensions and are there really more than three?
