In this module, you will learn: To round off the given number to the nearest tens, hundreds or thousand, observe the digit at ones, tens and hundreds place respectively. 2. If the observed digit is less than 5, keep the digits to its left same and change the considered digit and the digit to its right to zero. 3. If the observed digit is greater than or equal to 5, increase the digit to its left by one and change the considered digit and the digits to its right to zero.
In this module, you will learn:- The questions related to the estimation of sums and differences, For estimating the difference (or sum) to the nearest tens, hundreds or thousands, round off the given numbers to the nearest tens, hundreds or thousands respectively. Then the difference (or sum) of the rounded numbers.

Ten years from now, what do you want or expect your students to remember from your course? We realized that in ten years what matters will be how students approach a problem using the tools they carry with them—common sense and common knowledge—not the particular mathematics we chose for the curriculum. Using our text, students work regularly with real data in moderately complex everyday contexts, using mathematics as a tool and common sense as a guide. The focus is on problems suggested by the news of the day and topics that matter to students, like inflation, credit card debt, and loans. We use search engines, calculators, and spreadsheet programs as tools to reduce drudgery, explore patterns, and get information. Technology is an integral part of today's world—this text helps students use it thoughtfully and wisely. This second edition contains revised chapters and additional sections, updated examples and exercises, and complete rewrites of critical material based on feedback from students and teachers who have used this text. Our focus remains the same: to help students to think carefully—and critically—about numerical information in everyday contexts.

Improving the quality of education is an important endeavor of educational policy and TAL aims to contribute to this. TAL is a project initiated by the Dutch Ministry of Education, Culture and Sciences, and carried out by the Freudenthal Institute (FI) of Utrecht University and the Dutch National Institute for Curriculum Development (SLO), in collaboration with the Rotterdam Center for Educational Services (CED). The quality of education can be improved in many ways. TAL proposes to do this by providing insights into the broad outline of the learning-teaching process and its internal coherence. It aims to be a support for teachers alongside mathematics textbook series. Furthermore, TAL can provide extra support for teachers if it is incorporated into a circle of implementation.
Targeting Mathematics series consists of nine textbooks; one for Primer and eight textbooks for classes 1–8. These books have been formulated strictly in accordance with the Continuous and Comprehensive Evaluation (CCE) approach of Central Board of Secondary Education (CBSE) and are based on the latest syllabus. The series also conforms to the guidelines of National Curriculum Framework 2005. The books have been written by experienced and renowned authors.
Learning Objectives :- Learn estimating the products and estimating the quotients, Learn rounding off the given numbers and then find the product and quotient for the required estimated number.
Engaging Mathematics is a series of eight books for classes 1 to 8 based on the CISCE syllabus. The series follows an activity-oriented approach to make mathematics engaging for students through emphasizing connections between mathematics and day-to-day experiences.
