Book excerpt: This is part of a revised series of books based on research on the teaching of mathematics for class 4 in India earlier published on www.vidyaonline.net. This covers the NCERT syllabus for class 4.  The focus here is on laying a foundation for further learning of mathematics and understanding of concepts and procedures. Concepts are presented by videos, manipulatives, pictures, real-world situations, spoken and written words, and symbols. Automaticity (answering without thinking) of multiplication and division facts are emphasized. The teachers should provide more practice if necessary for mastery of the concepts, and procedures and use situations for exercises that are familiar to the children in the class. Ample opportunities are provided for applications of mathematics to real-world situations, reasoning, communication, and problem solving. The schools that can afford should provide concrete manipulatives such as counters, geometrical models, tangram pieces, blocks, geoboards, balances, fraction pieces, graphs, scissors, ropes. The schools that cannot afford teachers and/or students can make some of these and improvise for others. For example, they can make tangram pieces, 3-D models, balance, use dot paper for Geoboard, draw small circles for counters, use fraction chart for fraction pieces. Some activity sheets are provided that can be removed and used. Answers to selected exercises are provided.
