With a nifty extension running in a Chrome browser, you can: EquatIO renders the mathematics that you dictate (or type or write) on your computer or Chromebook. Watch it in action here: https://www.youtube.com/watch?v=smh5esAYWFA Then check out how EquatIO can enhance the use of exit tickets in the classroom, and four other classroom applications for it: http://okt.to/PbksOq Creators Texthelp developed this browser extension out of g(Math), a product more limited in scope. The free version of EquatIO lets you add its speech-to-text and other output to Google Docs. The premium version offers unlimited handwriting recognition, plus integration with Google Forms, Slides, Sheets, and Drawings. https://support.texthelp.com/index.php? action=artikel&cat=27&id=406&artlang=en -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- PoW taking place: Math problem-solving moment of the week "While I was doing this problem, I realized that you always have to look before you start just to make sure all units are the same, and if they aren't you need to convert them to one common unit. My answer is reasonable because ..." - Shell, highlighted in the Pre-Algebra PoW's latest solution http://mathforum.org/pows/solution.htm?publication=4923 -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- DRAWING WITH MATHPIX http://draw.mathpix.com/ The makers of Mathpix recently posted the results of "some fun" they had with their API and HTML canvas. Mathpix is the "snap, solve, graph and go" app first highlighted here in December. It instantly digitizes photographs of handwritten math taken on a smartphone, then simplifies or solves it step by step, with relevant lessons along the way. This latest experiment with Mathpix's optical character recognition technology typesets the math that you write in the graph-paper region of their new drawing interface. Click the "copy to clipboard" button to capture the LaTeX code for that formatted output. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- Now taking place: Math education conversation of the day "Trickier to work out -- which might be why the question.... The distance from the vertices of a sqrt(2), sqrt(2), sqrt(2) triangle to its center is (scribble, scribble) sqrt(2/3).... More could be said, but that's a start." - Jim, posted to the sci.math discussion http://mathforum.org/kb/message.jspa?messageID=10168018 -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- POLYHEDRON TEMPLATES http://polytemplate.com/ A website recently launched for interactively designing polyhedron models. Build your own net by choosing from among the five Platonic solids (tetrahedron, hexahedron, octahedron, dodecahedron, icosahedron), or using the lighter blue "advanced" button to specify its dimensions and the number of sides. Polyhedron Templates lets you truncate the resulting model as often as you like. To print out and fold up the your model, pick the tab types and sizes that you'd glue. The "data" link leads to a table of the edge length and vertex angle of every face of your 3D creation. We first learned about Polyhedron Templates as a suggestion to the Internet Math Library, which today boasts over 11,100 math and math education websites.
