10 Little Rubber Ducks by Eric Carle
"Ducks overboard!" shouts the captain, as a giant wave washes a box of 10 little rubber ducks off his cargo ship and into the sea. The ducks are swept away in various directions. One drifts west, where a friendly dolphin jumps over it. A whale sings to another. But as the sun sets, the 10th little rubber duck is left all alone, bobbing helplessly on the big wide
sea. Young readers and listeners will empathise with the little duck's plight - and will rejoice at the heartwarming surprise ending.
This book provides opportunities for children to count to ten as they follow the journey of each rubber duck. Each duck is referred to as the first, second, third, etc. which could be a nice starting point for a discussion of how we can use ordinal numbers to refer to objects.
