Summary: 
Geometric thinking is considered to be one of the most controversial thinkings. Many researches have observed that children have various opportunities to cultivate the elements of geometric thinking at different levels throughout mathematical activities. Having experimented, we found out that these puzzle games are both attractive and potential to develop visualization, imagination and thinking in terms of shapes. Tri Uan is a seven-piece tangram, which is popular in Vietnam. This article presents the research of geometric thinking components and geometric activities through Tri Uan in order to develop geometric thinking at each level in children.
Keywords:
