"In the 3rd century BCE, Eratosthenes calculated the circumference of the Earth to high precision."

"The Noon Day Project Measuring the Circumference of the Earth The Goal of the Noon Day Project is to have students measure the circumference of the earth using a method that was first used by Eratosthenes over 2000 years ago. Students at various sites around the world will measure shadows cast by a meter stick and compare their results. From this data students will be able to calculate the circumference of the earth."

To define a function: f = (x,y) -> x^2 + y^2 To evaluate: show f(3,4). If you exclude the arguments: show f you get: *function (x, y) { return add(pow(x, 2), pow(y, 2)); }*. That's really cool.* *Provides a great way to discuss functions both mathematically and computationally.

"The standards stress not only procedural skill but also conceptual understanding, to make sure students are learning and absorbing the critical information they need to succeed at higher levels - rather than the current practices by which many students learn enough to get by on the next test, but forget it shortly thereafter, only to review again the following year."

"Common Core State Standards. The standards clearly communicate what is expected of students at each grade level. This will allow our teachers to be better equipped to know exactly what they need to help students learn and establish individualized benchmarks for them. The Common Core State Standards focus on core conceptual understandings and procedures starting in the early grades, thus enabling teachers to take the time needed to teach core concepts and procedures well-and to give students the opportunity to master them."

"The Glean ComboCoin tool provides multiple levels of problem difficultly and works with classrooms at various grade levels. It's a fun tool to integrate with your teaching of fundamental--and typically serious--multiplication skills, including the distributive and associative properties of multiplication. Lesson Ideas and Classroom Activities: ComboCoin Jeopardy - large group (with a projector): Have students work individually or in teams to come up with combinations as quickly as possible. When they have a combination, they raise their hands and enter it into the ComboCoin game board. Each time a team finds a new combination, they receive a point."

"it is a powerful resource, very simple to use and available for students to use at home. Several new features have been added"

"Welcome to the Desmos Calculator! Use this calculator for graphing, for calculating, for sharing, for creating. Look on the right for help or inspiration. "

"Cool Stuff to do @ Home The activities are a part of The Tech's new IDEA (Innovation, Design, Exploration Activities) kits. They're a new endeavor for us here in the Programs Department, and we need your help and insight to make the kits program bigger, better, and more fun."

"A mathematician needs functions for the same reason that a builder needs hammers and drills. Tools transform things. So do functions. In fact, mathematicians often refer to them as "transformations" because of this. But instead of wood or steel, functions pound away on numbers and shapes and, sometimes, even on other functions."

"Brian Hayes explores this problem in the title essay of his recent book, "Group Theory in the Bedroom." Double entendres aside, the "group" in question here is a collection of mathematical actions - all the possible ways you could flip, rotate or overturn the mattress so that it still fits neatly on the bed frame."
