**Evidence 1 **: EDT 654 – Google Earth Lesson on Finding Perimeter and Area 

**Rationale 1 **: For this unit on perimeter and area that I taught for summer school, I started by having students find the perimeter and area of shapes that were drawn out for them. All students had to do was decide what shape the figure was and use the appropriate formulas to find the perimeter and area. After a day of practice, students were given a quiz on this skill.

The next part to this unit on perimeter and area was students had to find the measurements using a ruler to find the perimeter and area of a shape. We spent one day practicing this skill and then as their assessment, students had to find the perimeter and area of real buildings using Google Earth.

This lesson on perimeter and area demonstrated the following mathematics and technology standards:

**Mathematics **

B.12.4 In problem-solving situations involving the application of different number systems (natural, integers, rational*, real*) select and use appropriate C.12.2 Use geometric models* to solve mathematical and real-world problems D.12.3 Determine measurements indirectly

**Technology **

<span style="font-family: 'Arial','sans-serif';">A.12.3 Use a computer and productivity software to organize and create information <span style="font-family: 'Arial','sans-serif';">B.12.2 Develop information-seeking strategies <span style="font-family: 'Arial','sans-serif';">C.12.4 Demonstrate self-motivation and increasing responsibility for their learning

<span style="font-family: 'Arial','sans-serif';">The goal of this lesson was for students to be able to find the perimeter and area of real objects. Since perimeter and area is a concept used everyday to build and construct things, I feel that it is important that students have a good understanding of these concepts. Also, when perimeter and area is used in the real world, many times you must measure the necessary factors. Therefore, that is why I had students use Google Earth to find the necessary measurements to find perimeter and area.

<span style="font-family: 'Arial','sans-serif';">This lesson shows that I am able to use technology to create an authentic assessment that measures a student’s ability to perform this skill in the real world. As I mentioned before, the goal of this unit was for students to be able to find the perimeter and area of real objects. Since I did not have a class set of tape measures, I figured that Google Earth was the next best thing to use. Also, students were interested to find the perimeter and area of famous buildings since that would be very difficult using tape measures.

<span style="font-family: 'Arial','sans-serif';">When I used this lesson in summer school, I found that many students struggled to correctly find perimeter and area using Google Earth. The part students struggled with was not using Google Earth, but what parts of the object they needed to measure to find perimeter and area. Since most of the students in my class were not very strong in math, I think this type of assessment would work better for more advanced classes.

**<span style="font-family: 'Arial','sans-serif';">KSD **

**<span style="font-family: 'Arial','sans-serif';">8.K.1 The teacher understands the characteristics, uses, advantages and limitations of different types of assessments for evaluating how students learn, what they know and are able to do, and what kinds of experiences will support their further growth and development. ** <span style="font-family: 'Arial','sans-serif';">My main goal for this unit was for students to be able to find perimeter and area of objects in the real world. This is a skill I believe educated adults need to be able to do. I felt that by using Google Earth, I was able to accurately assess this skill and do it in a way that was enjoyable for students.

**<span style="font-family: 'Arial','sans-serif';">8.S.1 The teacher appropriately uses a variety of informal and formal assessment techniques to enhance her or his knowledge of learners, evaluate students’ progress and performances and modify teaching and learning strategies. ** <span style="font-family: 'Arial','sans-serif';">Since I knew I wanted to assess students at the end of the unit by using Google Earth, I used a natural progression of activities and assessments so students would have the skills needed for their final assessment. Along the way, I was able to identify aspects of perimeter and area that students were struggling with so that they would be able to be successful using Google Earth to find perimeter and area of real-life objects.

**<span style="font-family: 'Arial','sans-serif';">8.D.1 The teacher values ongoing assessment as essential to the instructional process and recognizes that many different assessment strategies, accurately and systematically used, are necessary to monitoring and promoting student learning. ** <span style="font-family: 'Arial','sans-serif';">Traditionally, students are assessed on perimeter and area by taking a test in which students are given the measurements of an object and asked to find the perimeter and area. As I mentioned, my goal for this unit was for students to be able to find perimeter and area of real life objects and not just shapes on a piece of paper. I felt that Google Earth was able to accomplish this goal and do it in a way that was meaningful to students.
