Willie Wiggle Wiggle Worm
Willie Worm is an enjoyable and challenging visual spatial problem, which encourages persistence in problem solving, as well as providing students with a purposeful reason for practicing counting and writing numbers from 1 to 25.

Here is an extension from Willie Wiggle Wiggle Worm: Given that Willie Wiggle Wiggle Worm is in some position, find the fewest number of clues you must give so that somebody else can figure it out.
For this position I think that five clues are needed, but I’m really not sure. This is difficult to prove, but a fun mini-competition. I wonder: For all positions in an NxN box, what are the greatest and smallest number of clues required?
Standards for Mathematical Practice
MathPickle puzzle and game designs engage a wide spectrum of student abilities while targeting the following Standards for Mathematical Practice:
MP1 Toughen up!
This is problem solving where our students develop grit and resiliency in the face of nasty, thorny problems. It is the most sought after skill for our students.
MP3 Work together!
This is collaborative problem solving in which students discuss their strategies to solve a problem and identify missteps in a failed solution. MathPickle recommends pairing up students for all its puzzles.
MP6 Be precise!
This is where our students learn to communicate using precise terminology. MathPickle encourages students not only to use the precise terms of others, but to invent and rigorously define their own terms.
MP7 Be observant!
One of the things that the human brain does very well is identify pattern. We sometimes do this too well and identify patterns that don't really exist.
