This diagnostic session aims to evaluate students' foundational knowledge of Colonial America, covering essential topics such as geography, economics, and significant historical figures. The session is structured into three parts: the first section focuses on identifying original British colonies using a historical map, assessing confidence in geographical understanding. The second part involves defining key economic and political terms including 'mercantilism' and 'monarchy,' with an emphasis on vocabulary confidence. The third section encourages critical thinking by discussing the geographical implications of the Ohio River Valley on potential conflicts between Britain and France. Following this, students will review historical figures that influenced colonial policy, predict the impact of trade on border policies, and reflect on the implications of competing land claims. The session concludes with a section for student reflection and notes for continuous improvement in understanding Colonial America.
