( )1. This picture book explores the life of a tree that has deep roots,long arms,and many children. She

provides shelter for many animals and bears fruit. The author uses colorful, simple, yet detailed watercolor

illustrations to convey her words. The charming pictures show the many aspects in the life of a tree down

to the caterpillars that eat the leaves. It is good for pre-school children.

( )2. This charming picture book highlights the life of a garden, from planting seeds to harvesting. With

the narrator as guide, the reader is led through a variety of free verse and occasionally rhymed poems that

fill in the story of a garden and its inhabitants. The pictures, delightful watercolors in bright pastels, add to

the whimsical feel of the poems. Young readers will certainly enjoy this fun and fanciful text.

( )3. This is a story from 1956 which introduces a little boy who likes to go fishing with a tree limb, a

woman, and a pin. Although he never catches anything, on this particular day he finally does hook three big

ones, but the little one gets away. The boy pulls them home in his wagon and his mother cooks them for

supper. The swinging rhythms of the text and the good humor evident in the illustrations remain fun for the

youngest readers.

( )4. This useful, attractive, oversize volume uses its height well, employing a tree metaphor to show the

earth's various kinds of life and how all living things from bacteria to the largest mammals, are related. Each

spread covers one branch of the animal kingdom. To make the enormity of species understandable, Strauss

equates individual species (e. g.,1 0,000 bacteria) with one leaf on the tree.

( )5. This is a story about how a grandfather teaches his eager granddaughter to catch speckled trout from

the stream in springtime. After a whole day on the lake, only Grandpa is lucky. The next morning the young

fisherman hurries to the dock alone, and soon she hooks the catch of a lifetime. Young readers will appreciate

this story that celebrates the special bond between the older and younger generation, while brilliant watercolor

illustrations capture the beauty of the natural world.
