      EquatIO | Drawing with Mathpix | Polyhedron Templates



 Have you ever wanted to display perfectly typeset mathematics
 just by speaking symbols and numbers?

 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:


 Then check out how EquatIO can enhance the use of exit tickets
 in the classroom, and four other classroom applications for it:


 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.



    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 ..."

                      DRAWING WITH MATHPIX


 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


                      POLYHEDRON TEMPLATES


 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. Share your own by visiting
