Teaching content: PEP primary school mathematics third grade Volume 58 page fifth unit first lesson case 1 and do one. Teaching Objectives: 1. In the process of solving specific problems, master the whole ten, the whole hundred multiplied by ten and two digits multiplied by ten, the whole hundred of the port count method, and can make the port count. 2. In specific situations, through self-exploration and understanding of the diversity of problem-solving strategies, we can strengthen the arithmetic and algorithm in solving practical problems. In the process of solving practical problems, enrich students' inquiry experience. Teaching heavy and difficult: Teaching focus: Ten, the whole hundred multiplied by ten and two digits multiplied by ten, the whole number of mouth count method. Difficulties in teaching: the whole ten, the whole hundred multiplied by ten and two digits by ten, the whole hundreds of arithmetic and algorithm.
