What approach should Ms. Klein take to improve her teaching practice regarding tessellations?

Providing clear instructions and a worksheet before the activity is a highly effective approach for improving Ms. Klein's teaching practice regarding tessellations. This method helps students understand the objectives, expectations, and steps involved in the activity, which is crucial for engaging them effectively. By having a structured framework, students can focus better on the concepts being taught and feel more prepared to tackle the activity.

Clear instructions also promote a better understanding of key concepts, such as the properties that define tessellations, and guide students through the process of creating or recognizing them. This approach lays a solid foundation for learning and helps prevent confusion, allowing students to fully engage with the subject matter. Worksheets can reinforce these instructions by giving students a tangible resource to refer to, ensuring they can follow along and actively participate in the lesson.

This method contrasts with the other choices, which do not adequately foster understanding or engagement with the concept of tessellations.
