Abstract: Associative ability plays an important role in improving students' mathematics ability, promoting students' thinking development and activating students' mathematics knowledge.In mathematics teaching, by constructing a mathematical knowledge network, constructing a student's association system, using the method of the combination of number and shape, pattern complement, and similar contrast method to cultivate students' associative ability can improve students' associative ability in mathematics, so that students in mathematics learning can draw inferences about other case from one instance and bring all knowledge together and understand thoroughly.

Key words: mathematics teaching, associative ability, number combination method, pattern complement method
