Abstract Two dimensional map integrated element valence, composition of matter particles and transformation between substances into one map. Teaching practice proved that construction of two-dimension map of elements could well connected the main knowledge of junior and senior high school chemistry, relieved teaching time pressure, promoted students' cognition development, realized the students' autonomous learning ability, expanded students' creative thinking, and prepared students for their lifelong development. The construction of "two dimensional map" provided a feasible teaching mode for the infiltration of core chemistry concepts.
