Geometry Pad is a dynamic geometry application for iPad.  With the Geometry Pad you can create fundamental geometric shapes, explore and change their properties and calculate metrics. The shapes are displayed on a scrollable and zoomable workbook with a rectangular coordinate system. The following tools are built into the application:  - Move and scale. Scroll the workbook by your finger. Pinch and zoom the content of your workbook. Move and modify shapes.  - Point. Plot a point on the workbook. Customize point name and color.  - Line. Create a line. Customize line style, color and start/end points. Calculate line length (distance between points).  - Midpoint for lines. Show/hide midpoint for lines and polygon sides. Snap to midpoints.  - Parallel, perpendicular and tangent lines. The lines can be created as easily as regular lines. Just create and move the line until it automatically snaps to parallel, perpendicular or tangent.  - Angle. Create an angle with up to 1 degree precision. Customize angle line style and color.  - Triangle. Create a triangle of one of the predefined types: regular, right triangle, isosceles, equilateral. Customize sides style and color. Calculate triangle perimeter and area. Calculate inner angles of the triangle and length of its sides.  - Triangle lines. Create altitude, bisector and median lines in a triangle. Calculate length of triangle lines. Customize lines style and color.  - Quadrilateral. Create a quadrilateral of one of the predefined types: regular, square, rectangle, parallelogram, rhombus. Customize sides style and color. Calculate quadrilateral perimeter and area. Calculate inner angles of the quadrilateral and length of its sides.  - Circle. Create a circle. Calculate circle perimeter and area. Easily create circles inscribed into a triangle by placing circle's center close enough to the incenter of a triangle.  - Circle radius and chord. Create radius and chord lines for a circle. Customize lines style and c

SUPERB! Place the numbers on the number line. Loads of levels. Negative numbers and decimals. Play against the clock for a score. My class's favourite warm up, useful throughout school from year 3 to year 6.

Registration opened earlier this week for a new short intervention course on Stanford University's free on-line platform. Designed for teachers of math (K-12) or for other helpers of students, such as parents, "How to Learn Math" consists of eight 10 to 15 minute-long sessions intended to change students' relationships with math. In addition to videos of Professor of Mathematics Education Jo Boaler, research ideas, and peer- and self-assessments, her course includes interviews with students, Udacity's Sebastian Thrun, Stanford Professor Carol Dweck, and others. The self-paced course launches Monday, 15 July, and closes Friday, 27 September. Boaler, the author of books such as What's Math Got To Do With It?, also serves as editor of the research commentary section of NCTM's Journal for Research in Mathematics Education (JRME).

This lesson involves students in collecting data, organizing data into a line plot, discussing statistics, calculating mean, median and mode and consumer awareness.

A rare and fascinating look inside the world's largest computer manufacturer, Dell Inc., where thousands of computers are custom-built and shipped around the world every day. From the call center to the assembly line, one thing is certain: The whole operation relies on math skills every step of the way.

"In this section, you will find some fun ways to learn about math. You can start out with Estimation of Length, Place Value and Weight and Capacity. If you want something more challenging, take a look at Line Symmetry, Patterns and Tangrams."

Informal Geometry comes to us through MathMastery -- November's Featured Partner. This video-rich content provides students with the concepts and skills necessary for finding the perimeter, area, surface area and volume of common geometric figures; graphing equations on the coordinate system and deriving the equation for the third line from a pair of points; using the Pythagorean Theorem to solve problems involving right triangles; determining if triangles are similar and finding an unknown side in similar triangles; and determining unknown angles in figures by calculating the sum of the interior angles.
