Image from store Graspable Math Sidebar
Description from store Graspable Math lets you turn static mathematical expressions into dynamic objects! Use our full-size app at https://graspablemath.com/canvas or this sidebar extension. Both allow you to drag most static math expressions from Wikipedia or many other pages onto the canvas to make them interactive. Our dynamic algebra notation is backed by research from Indiana University Bloomington and Worcester Polytechnic Institute. Use this extension to open a sidebar that lets you work on any algebra on the page. After you drag and drop formulas into the sidebar or enter them directly, you can then interact with the terms to create algebraic derivations. Drag and drop from other pages than Wikipedia might or might not work. Contact us about adding support for your favorite page! Features: – drag text and Wikipedia images of math expressions into the sidebar to make them interactive – interact with expressions using mouse gestures: https://graspablemath.com/tutorial/ – move whole derivations around by picking them up on their margin – pack and unpack lines of a derivation by dragging their handles up and down – copy a line of a derivation by dragging its handle to the side and dropping it on a free space – substitute values by dragging one side of an equation onto matching targets Why does this extension need access to all my tabs? This is necessary to add the GM sidebar into the current page when you press the GM extension button. Nothing happens unless you press the GM button and we do not gather information about the content of the page. Recent Updates: Version 1.3.0 - update to GM version 2.23.9 (new math actions, many fixes) - fixes dragging math expressions onto the sidebar Version 1.2.0 - update to GM version 2.3.3 (new fraction gestures, better target visualizations, many bugs fixed) - better login flow when saving your work (no need to log into Chrome) Version 1.1.0 - updated to lastest GM version 2.1.6: now shows where to place picked up terms - new saving, loading and sharing menus, connected to your https://graspablemath.com/canvas account Version 1.0.1 - added a how-to video for the sidebar to the help menu Version 1.0.0 - update to Graspable Math version 1.0.2 - new substitution system, more control over when to trigger algebra actions, and much more - replaced input field with insert menu + math keyboard Privacy note: We are using google analytics and our own server to record anonymous usage data that helps us improve Graspable Math and this extension.

  • (2018-10-03, v:1.2.0) marwoo99: extension not working
    I have successfully downloaded the extension onto Chrome (which is up to date). I get the sidebar when I click the extension icon but it is 100% blank. When I attempt to use the canvas, it too is blank. No tools appear. I watched this being used by a fellow teacher on her computer yesterday. Neither of us could get mine to function. I'm very disappointed - my son really needs this!

  • (2017-05-29, v:1.0.1) Thành Vinh Lê: Use a standalone screen instead of sidebar
    I think you should make a standalone screen instead of importing it into the webpage as a sidebar. Because other webpages might use side bar too (examples: Facebook, Youtube). When I use this extension on Facebook, the chat bar is in front of the Math sidebar so I can't use it on facebook. Same as youtube.
  • (2017-04-27, v:1.0.1) Add tutorials
    i think it would be really helpful for students like me. For example, i couldn't understand the lesson our teacher discussed. we can review it here for more productivity. I wish this was helpful. I wish you would add this for people who aren't good at math like me. =)

    Hi, I am interested in acquiring your extension "Graspable Math Sidebar". Please contact me at: [email protected]
  • (2015-09-26, v:0.0.2) Ryan Sonognini: Adding equation properties
    I think it would be helpful to see which properties were used as an equation is changed. The properties could be listed to the side and pasted after a user changes something. Maybe there could be an option to toggle this info on and off as it would clutter the info a little bit. For example: 2x+4=2 2x=2-4 Sub. prop. of eq. By the way, I am a math teacher and will be using this with my students. Thank you. I love it!
  • (2015-09-26, v:0.0.2) Ryan Sonognini: Distributing a negative
    Absolutely love it! When clicking a negative number to distribute, it grabs the whole expression instead of just the negative number.
