LOTS AND LOTS

The tricky concept of relative number receives a cheery elucidation in this oversized board book. Buzzy the donkey has “one balloon”; his rabbit friend has “some balloons”; together with their hot-air balloon–flying alligator pal, they have “many balloons.” Bolam’s bright, sharply outlined characters brim with energy; each spread makes its concept manifest, with gentle humor. A winner.
