ADDverse includes two beautifully illustrated poems for young children: Farmer Yercle’s Circles provides a visit to the Circle 8, a farm where nothing is square or even oval; Peter Pattern explores the concept of repeating pattern, providing a hidden pattern game on every page. Both the geometry of two and three dimensional shapes and pattern recognition, which leads to the iterative functions of algebra, are important strands within mathematics’ curriculum standards in the early grades.

“Penn is a Pied Piper; no child will be able to resist the music of her numbers.” – Duncan Robinson, CBE, Master of Magdalene College, Cambridge University
