Discuss how the chosen standards and problems build student understanding of plane geometry or measurement of plane figures across the three K–6 grade levels selected in part A1.

A. Study the plane geometry or measurement of plane figures content standards for your state and do the following:

1. List three content standards from your state that apply to plane geometry or measurement of plane figures for grades K–6. The three selected standards must represent three different grade levels.

2. Write a sample problem for each of the three standards to illustrate the evolution of student understanding.

3. Provide a solution for each problem that demonstrates each step or explains the thinking process involved in determining the solution.

4. Discuss how the chosen standards and problems build student understanding of plane geometry or measurement of plane figures across the three K–6 grade levels selected in part A1.

B. Watch the “A Table for 22” video and do the following:

1. Describe one instructional strategy the teacher successfully incorporates in the geometry lesson and explain how it helped students develop a deeper understanding of plane geometry.

2. Explain how you could incorporate one strategy from this lesson into your own instructional practice.

3. Describe how you would modify this lesson for students with special needs.

C. Prepare to create an original lesson plan on plane geometry or measurement of plane figures by doing the following:

1. Describe an evidence-based instructional strategy that will be incorporated into your original lesson plan.

a. Explain why the chosen instructional strategy would be beneficial in a lesson on plane geometry or measurement of plane figures using evidence from a credible source to support your selection.

D. Using the attached “Direct Instruction Lesson Plan Template,” design an original lesson plan for elementary (K–6) mathematics that addresses the topic of plane geometry or measurement of plane figures. Submit the lesson plan as a separate document from parts A–C.

Note: The lesson plan should be detailed, complete, descriptive, and reflective. As a general rule, include enough detail so that a non-mathematics substitute teacher could teach the lesson using your plan.

1. In the “Instructional Strategies and Learning Tasks” section of the lesson plan template, identify the instructional strategy that was selected in part C1 and explain how it was incorporated into the lesson.

E. Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or summarized.

F. Demonstrate professional communication in the content and presentation of your submission.
