To this end teachers should be based on the content of teaching materials, to seize the psychological characteristics of children’s curiosity strong, carefully set suspect, create suspense, deliberately put some mathematical knowledge cast a mysterious color, so that students in a kind of Up to mouth to say but failed "imbalance, causing students to explore the desire to promote their active participation in learning.
