Objective: Using the unit fraction blocks provided, find a way to make 1 in two different ways.  Click and drag the fractions to move them around.  The fractions will snap to the corners of the boxes, but not to each other; I couldn't figure out how to program that!  So you might need to look closely to make sure things align.  There are many different solutions, 
at least eighteen nineteen twenty-five distinct ones.  Thanks go to jQuery for powering this!  Created by Paul Varley (Bluesky: @paulpower.bsky.social). Last updated 26th August 2025;
