【Teaching content】 Sujiao version of the fifth grade mathematics “the nature of decimals.” Teaching Objectives 1. Let students in the real situation through the conjecture, verification, comparison, induction and other mathematical activities to perceive, understand and grasp the basic nature of the decimal; develop students’ abstracted abilities, abilities. 2. Let students learn to use the nature of decimals to simplify or rewrite decimals; infiltration transformation mathematical thinking. Difficult teaching hard to understand the nature of decimals, the nature of the decimal will be used to simplify or rewrite the decimal. 【Teaching aids】 squares of paper, small blackboards and cards. 【Teaching Design】 First, set the problem - guide thinking 1. Careful observation, serious thinking, what did you find?
