This counting book takes the idea of 'one family' and shows just how many different combinations can make up this single entity. Colourful double-page spreads celebrate all kinds of family units ranging from single parent to multi-generational groupings, with many variations on racial background, skin shade, gender combination and age. The simple rhythmic text builds a cumulative refrain on the unity of these by its examples of other individual items with multiple components ('one ring of keys'; 'one shelf of books') whilst offering lots of opportunities for counting from one to ten whilst enjoying the visual detail of domestic interiors and friendly neighbourhood street scenes.
