With a larger goal to promote 21st century skills such as critical thinking and problem solving, the Central Board of Secondary Education has shared a Mathematical Literacy: Practice Book for Students.
This Work Book is designed to allow learners of classes 7th to 10th to examine problems related to real life situations and solve such problems.
The design of this book promotes learners to work in a self-directed manner with minimal support of teachers or parents.
This Practice Book is available here - Mathematical Literacy: Practice Book for Students
You can also download from CBSE Website at the link http://cbseacademic.nic.in/web_material/Manuals/math-literacy.pdf and on the DIKSHA portal at http://bit.ly/MathsCCTPractice.
It is hoped that students and teachers would circulate this widely for the benefit of the students. Students would enjoy working in this Practice Book, especially during the time when regular classes/schools do not resume.
