# CCE : List of Activities in Mathematics For Classes III To VIII - 2008

## Mathematics Laboratory

The concept of Mathematics Laboratory has been introduced by the Board in its affiliated schools with the objective of

• Making teaching and learning of the subject interactive, participatory, funfilling and joyful from primary stage of schooling.
• Strengthening the learning of mathematical concepts through concrete materials and hands-on-experiences.
• Relating classroom learning to real life situations and discourage rote and mechanical learning.

The Board has already published detailed guidelines for Mathematical Laboratory in schools for class IX and class X including hands-on activities to be done during these academic years.

Given below is the list of activities to be done by the students in classes III to VIII during each academic year.
