摘要：This study has been prepared with the purpose to investigate proof teaching on early grades. The purpose of this study is to investigate proof on 7th grades and 7th grade students’ performance on proof. Data have been obtained during lessons focused on proof teaching by video recording. At the end of the research it is seen that proof can be adapted to this elementary grade and students could prove depending on their mathematical knowledge, their ion capacity, and their algebra knowledge.
