The Central Board of Secondary Education has launched a Mathematics practice book on its official website. It is designed for students of class 7 to 10. The Mathematical Literacy: Practice Book will help students examine the problems related to real-life situations and help them solve such problems.
The Mathematics Workbook is designed in such a way that students can understand the concepts by themselves and solve the mathematical problems with minimal support from teachers or parents. The book also provides an opportunity for students to explore their reasoning and quantitative skills. Since CBSE reduced the syllabus by 30%, this is the first insight into what the changed syllabus pattern question papers would look like. You must go through it once before sitting for your board exams.
