Virtual Pentominoes

Henri Picciotto

Move the pieces by dragging them.
Drag the o vertex to rotate them.
Some can be flipped by clicking the • vertex.
Change the size of the rectangle by dragging its • vertex.
Use the checkboxes to hide or show those vertices, and the rectangle.
Use the Polygon tool to create non-rectangle puzzles.

Why do only some of the pentominoes have a "flip" option?
What size rectangles can be covered with pentominoes?
Make puzzles by doubling or tripling pentomino dimensions.

This book, co-authored with Prof. Robin Pemantle, is a 360°
view on math pedagogy. We acknowledge the complexity of
teaching, avoid one-size-fits-all oversimplification, and offer
discussion questions for departments and preservice classes.

There Is No One Way to Teach Math:
Actionable Ideas for Grades 6-12.
