Selecting appropriate activities is the first step in a lesson progression.

The statement that selecting appropriate activities is the first step in a lesson progression is indeed true. When planning a lesson, the selection of activities is crucial because it sets the foundation for how students will engage with the material and how effectively they will learn. Appropriate activities are tailored to the learning objectives and the students' existing knowledge and skills, making them essential for fostering an effective learning environment.

In lesson design, determining activities first allows the instructor to ensure that the chosen methods align with the overall goals of the lesson. It also helps in creating a structure where subsequent steps, such as assessment and reflection, can build upon the initial activities. Thus, by selecting the right activities, educators can better facilitate student engagement and understanding throughout the lesson.
