估算（Estimate） How to make estimation teaching more exciting? Abstract: estimation is an important mathematical thinking method and mathematical ability. Students grasp the scientific methods of calculation and can flexibly use it, which will play a positive role in improving the students ability of analysis and judgment and training students thinking depth, flexibility and originality. Therefore, it is imperative for teachers to teach them to estimate and to estimate them well. Teachers make the teaching more exciting estimates, a reality through the following ways, cultivate awareness of estimation; two, the cultivation of students number sense of estimation; three, on the three level to improve the estimation of teaching; four, through Bisuan effectively promote the teaching of calculation. Mathematical estimation should be the principle to follow, it is the mental form in the allowed range, as simple as possible. But its formation is not accomplished overnight. It requires teachers to pay more attention to the teaching of estimation, and needs teachers to develop it more effectively and scientifically for a long time [key word]: estimate the importance of teaching, the necessity, the training way is wonderful Estimation is an important mathematical thought, method and mathematical ability. Students grasp the scientific methods of calculation and can flexibly use it, which will play a positive role in improving the students ability of analysis and judgment and training students thinking depth, flexibility and originality. [1]. But the estimation teaching situation is unsatisfactory, and it is not clear how to make estimation teaching more exciting. Mathematics curriculum standard clearly pointed out: estimation has been widely used in daily life and mathematics learning, cultivating students awareness of estimation, estimation of ability development of the students, let the students have a good number sense, has important value. Estimation has become a hot topic in
