New to the OBH bookshop - The Great Deci-Balls & The Magic Number Box, by L.J. Tytula, illustrated by Sarah Tytula.
A fun, clever book that explains to children how the decimal system works, using multiple intelligences.
The book follows Deci-Ball characters falling into the Magic Number Box using a nursery rhyme style that can be sung as a melody. At the end of the book, children will understand why the number ten is represented by 1 and 0.
