There are three versions of this stencil.
The first is simply just the infinite cloner letters to drag in a box to create words. (A teacher adaptation I use is to premake the words and fade them with properties to create a match, see the sample page included at the end.)
The second version adds sound on each letter.
The third version adds sound, plus a musical "timer" of 30 seconds when the WORD OF THE DAY box is pressed.
