CLASSKLAP AND NCF Education plays a crucial role in shaping the future of our children and 251 empowering them to become well-rounded individuals. The latest National 4 3 Curriculum Framework (NCF), furthering the vision of the National Education Policy (NEP) 2020, focuses on fostering creativity, critical thinking, and problem-solving skills while also nurturing values of inclusivity, collaboration and democratic citizenship. The development of foundational literacy and numeracy is also a core goal of the NCF. ClassKlap by Eupheus partners with schools, supporting them through the steps of planning, teaching, learning, personal revision and assessment to equip students with the desired knowledge and skills relevant to the 21st century. The present series is a learning resource that not only meets the requirements of the NCF but also engages and captivates young minds. Here are some salient features of this series. NCF-aligned learning tool Description Skill-based lessons in textbook and workbook Lessons are structured as per Bloom’s Revised Taxonomy Inquiry-based lessons (Remember-Understand-Apply-Analyse-Evaluate-Create) and LSRW in textbook and (Listening-Speaking-Reading-Writing) skills for English. workbook Lessons are structured based on a Socratic approach using a Highlight features question-answer format, aiming at discovery-based learning as per NCF guidelines. Exploratory activities in the workbook facilitate holistic Practice Worksheets learning of the skills and concepts and foster a sense of curiosity and exploration among students. Features such as Poetry Appreciation, Maths Lab, Think Like a Scientist, Life Skills and others help learners engage in research, application-oriented learning and the development of scientific temper; Student Reflection sheets foster the skill of reflecting on one’s own learning progress. Practice Worksheets are aligned with the goals of sharpening critical thinking, evidence-based thinking and higher-order thinking skills, as per NCF guidelines. The books contain the following overarching features recommended in the NCF: a logical and spiralling progression of frameworks adopted for Grammar, Maths and EVS inclusive representation of gender and diversity for the heterogeneous Indian classroom learner-centred content, vibrant illustrations, diagrams and photographs along with age-appropriate language a variety of question types with scaffolded and independent practice to meet the needs of different students We are confident that this series will serve as a valuable tool to accomplish the aims of the NCF and help transform teaching-learning in classrooms. We sincerely hope that our young learners develop genuine curiosity and love for learning. Nameslip_Visa_G3_Maths_TB_P1.indd 6 7/21/2023 7:04:20 PM

DO It Yourself Do you know that estimation and rounding off can help us in different kinds of situations? Read this scenario. Suhas used a calculator to do some calculations. He added 436 881 and 745 and this is what the calculator showed: Suhas wonders if that is correct. He quickly calculates an estimate in his mind: “400 plus 700 is 1100. So how is 436 + 745 less than that? Oops! I must have typed 1 instead of 4.” Without estimating the sum by rounding off, he would have made a mistake even though he was using a calculator. Remember to always double check by estimating when you use a calculator or a computer to avoid errors. Estimation is an important and useful skill. In fact, estimation is not always about calculating. You can also try to estimate the number of things you see in a place, how long something will take and so on. 24 Addition Ascend_Maths_Book_WB_Part1.indb 24 7/13/2023 6:22:38 PM
