Dear Teacher,

We all know that children enjoy nature around them- the trees, the

plants, the animals, the birds and the rain. This book starts from their life

experiences i.e what they have seen and enjoyed. The activities are

based on their own experiences, about the people and the world around

them .

Children may know a few songs and stories when they come to school.

Quite naturally they enjoy listening stories, singing songs and playing games. So

we have included pleasant songs, enjoyable stories, thought provoking

activities and games. Several opportunities have been provided to kindle the

imagination of the children. They can make up stories, act them out, sing and

dance joyfully.

Children love to draw. This natural ability to draw and be creative has

scope in simple line drawing, imaginative drawing and colouring activities. Every

chapter has "I can" activities that provide a scope for self-evaluation. Every

child has different life experiences. We need to provide time for discussions

so that children share their thoughts, ideas and observations. An atmosphere

conducive to raise questions must be provided in the classroom.

Learning does not take place only in the classroom. Learning should be

extended to the outdoors where children will learn happily. Many people help us

in our daily life. If children can interact with them, it will widen their

understanding and build respect for their work.

Science is a part of everyday life and can be understood by observation.

A love for nature and caring for it should be inculcated in the formative years ofchildhood.
