Mathematics classroom resources

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).

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
