估算,作为一种传递数学知识的重要方式,它代表着一种教学思想。只有让学生在数学学习的过程中真正认识到估算的强大应用效果,学生才能够充分发挥主观能动性,积极主动地参与到数学估算学习中,才能提升估算速度以及准确性。本文针对教师在估算教学中所存在的问题,并根据自己的教学实践,为提升学生数学估算能力,探讨“让估算与智慧相遇”的一种新的教学策略。一、活学活用,为估算走进现实生活创造条件1.利用情境创设的教学方式,让学生感
Estimating, as an important way of conveying mathematical knowledge, represents a teaching philosophy. Only by enabling students to truly recognize the powerful application of estimation in the process of mathematics learning can students fully utilize their initiative and participate actively in mathematical estimation learning to improve their estimation speed and accuracy. In this paper, aiming at the existing problems of teachers in estimating teaching and according to their own teaching practice, in order to improve students’ mathematical estimation ability, this paper discusses a new teaching strategy of “Encounter Estimation and Wisdom”. First, learn to use, to create conditions for estimation into the real life 1. The use of context-based teaching methods to enable students to feel
