, FOREWORD
The National Education Policy (NEP) 2020 envisages a system of
education in the country that is rooted in an Indian ethos and its
civilisational accomplishments in all fields of knowledge and human
endeavour. At the same time, it aims to prepare students to engage
constructively with the opportunities and challenges of the twenty-first
century. The basis for this aspirational vision has been well laid
out by the National Curriculum Framework for School Education
(NCF-SE) 2023 across curricular areas at all stages. By nurturing
students’ inherent abilities across all five planes of human existence
(pañchakośhas), the Foundational and Preparatory Stages set the
Stage for further learning at the Middle Stage. Spanning Grades 6 to
8, the Middle Stage serves as a critical three-year bridge between the
Preparatory and Secondary Stages.
The NCF-SE 2023, at the Middle Stage, aims to equip students with
the skills that are needed to grow, as they advance in their lives. It aims
to enhance their analytical, descriptive, and narrative capabilities,
and to prepare them for the challenges and opportunities that await
them. A diverse curriculum, covering nine subjects ranging from
three languages—including at least two languages native to India—
to Science, Mathematics, Social Sciences, Art Education, Physical
Education and Well-being, and Vocational Education promotes their
holistic development.
Such a transformative learning culture requires certain essential
conditions. One of them is to have appropriate textbooks in different
curricular areas, as these textbooks are intended to play a central role
in mediating between content and pedagogy’s role that helps strike
a judicious balance between direct instruction and opportunities
for exploration and inquiry. Among the other conditions, classroom
arrangement and teacher preparation are crucial to establish
conceptual connections both within and across curricular areas.
The National Council of Educational Research and Training (NCERT),
on its part, is committed to providing students with such high-quality
textbooks. Various Curricular Area Groups (CAGs), which have been
constituted for this purpose, comprising notable subject-experts,
pedagogues, and practising teachers as their members, have made all
possible efforts to develop such textbooks. Ganita Prakash, the textbook
of mathematics for Grade 8 (Part 1) is designed to make learning fun,
engaging, and meaningful. Aligned with NEP 2020 and NCF-SE 2023, the
textbook continues to foster the spirit of experiential and inquiry-based
learning, a spirit already introduced in the mathematics textbooks for
Grades 6 and 7. It encourages students to ask questions, think critically,
and understand concepts of mathematics through real-world contexts.
