Ready for a little rainbow magic to brighten your "false spring" this month?  Check out these template for Jamboard from Control-Alt-Achieve (Eric Curts).  Much like the rainbow paper that kids can scratch off, these templates use the Jamboard eraser tool to uncover a brightly colored background as they write and draw shapes and letters on the Jamboard.  Try using one of these in your upcoming lessons and you can probably even get a smile out of your most jaded high school senior!
