Khan Academy Geometry Projects - PBL Anybody can aim a laser pointer to hit a target. But can you do it with an obstacle in your way? How about multiple obstacles? In this project, students will create and play a game in which the object is to maneuver a laser through a maze of obstacles to hit a target. To maneuver a laser, students will calculate the exact placement of multiple mirrors to reflect the beam of light through the game board. Challenges added throughout the game require students to understand and apply various geometric concepts.

Explore the properties of a straight line graph Move the m and b slider bars to explore the properties of a straight line graph. Look at The effect of changes in m The effect of changes in b The effect of a negative value of m The effect of a negative value of b How to create a horizontal line Read more about the Equation of a Straight Line Now see how two points can change the line equation. Try to make: y = 2x + 1 y = -2x -1 y = x y = 1 x = 1 Computational Skills for Biology Students June 2006 Why is it important to develop computer savvy students of biology? Understanding quantitative research is critical to grasping biology. A good fraction of modern biology is heavily quantitative. Photo: Microsoft Images. Gross: A good fraction of modern biology is heavily quantitative, and one of the main complaints that I have heard for a very long time from biologists is that students do not have the capability to carry out the basic quantitative research that is critical to all modern biology across the spectrum. Graphing is a required basic skill. One of the most distressing comments has been about the simplest things: reading, interpreting, and producing graphs—simple graphs that students have seen again and again since they were in elementary and middle school. Perhaps the simplest illustration of this point is the basic way we communicate science, which requires a quantitative framework for understanding. How do teachers go about helping students become more computer savvy?

Math in Daily Life When you buy a car, follow a recipe, or decorate your home, you're using math principles. People have been using these same principles for thousands of years, across countries and continents. Whether you're sailing a boat off the coast of Japan or building a house in Peru, you're using math to get things done. How can math be so universal? Join us as we explore how math can help us in our daily lives. Ready to get started?

Monthly Index page::2011 10 Why do this problem? This activity can be a good start for exploring the special properties of shapes. Children benefit from lots of informal play with linking shapes such as Polydron, during which time they conceptualise the different characteristics of 2-d shapes and visualise how they might fold up to make 3-d shapes. Possible approach Ask the children to make some squares using Polydron. What is the same/different about them? You could bring in the language of similarity - all squares are the same shape but may be different sizes. The pentomino activity is not a new one, but using Polydron allows children to try lots of examples. Key questions What can you tell me about the square polydrons and the triangular polydrons? What is the same about them? What could 'bigger' mean? Before you fold them up, can you tell what 3-d shape they will make? Possible extension What if you had six squares joined together (hexominoes)? Possible support

NSDL.org - National Science Digital Library Web 2.0 Tools for Math Educators By Laura Turner This is a continuing series on Web2.0 and other web-based tools for educators.
