The Hummingbird series of Primary Books from I to V are based on National Curriculum Framework (NCF) 2005 and the new Syllabi for classes at the Elementary Level.
In the guidelines some of the objectives of teaching the different subjects at primary stage are:
• to train children to locate and comprehend relationships between the natural, social and cultural environment;
• to nurture the curiosity and creativity of the child particularly in relation to the natural environment;
• to develop an awareness about environmental issues;
• to engage the child in exploratory and hands-on activities.
The Hummingbird series focuses on themes that allow for a connected and interrelated understanding to develop and trigger the child’s thinking in new directions. They connect knowledge to the child’s life outside the classroom and also provide an overall development of children.
The series comprises of textbooks on:
MATHEMATICS Children need to develop a positive attitude towards and a liking for Mathematics at the primary stage, along with the cognitive skills and concepts that they acquire. The content includes Mathematical games, puzzles and stories that help in making connections between Mathematics and everyday thinking.
ENGLISH An integrated approach to the teaching of language is of particular relevance at the primary level. The books address different skills of language, namely listening, speaking, reading and writing, which focus on across the curriculum approach through a variety of genres – poems, stories, role-plays and drama to develop the language skills creatively.
SCIENCE Science education should develop competence and encourage inventiveness and creativity. The textbooks incorporate activities, observation, experimentation and encourage an active approach to science, connecting it to the world around the child, rather than information based learning.
SOCIAL SCIENCE The textbooks provide the social, cultural and analytical skills required to adjust to an increasingly interdependent world. The focus of the books is on a conceptual understanding rather than lining up facts to be memorized.
ENVIRONMENTAL STUDIES Environmental Studies is a subject dealing with Man’s relation to his whole environment, viz. his surroundings, his home, his neighbourhood, his city or town, extending ever outward. The books contextualize the relevance of the subject and bring it to life.
The textbooks present the subjects in a clear, concise, logical and chronological manner. It is expected that this new series will inspire the children to analyse, demonstrate and transform their world view.

To show 4-digit numbers on an abacus, we need an abacus with 4 spikes, starting
from the right, the number of beads in the spikes should show ones, tens, hundreds
and thousands respectively.
The abacus shows the numeral 5,346. We read it as :
Five thousand three hundred forty-six.
Read the abacus and write the numeral and number name.
