What is the purpose of assessments done before starting a unit?

The purpose of assessments conducted before starting a unit primarily focuses on gauging students' knowledge of the upcoming unit topic. By identifying what students already understand, teachers can tailor their instruction more effectively, ensuring that lessons build on existing knowledge and address any misconceptions before introducing new content. This initial assessment provides valuable insights into the students’ starting points, allowing for differentiated instruction that meets the diverse needs of the classroom. It sets the foundation for a more targeted and effective teaching strategy, ultimately enhancing student learning and engagement in the unit.
