This lesson will be for my mathematics class. It will use technology to further assist the students comprehension as it relates to the material. Often times classroom lessons no matter how creative become boring to some. I feel that is my responsibility to connect to those learners who may struggle in class. This gives them the opportunity to work both independently and intuitively. This mathematics lesson is extremely important.
Of course there are many digital options available,but for this lesson I think posting a blog with embedded sound bites is best. This way the student can follow the objectives along with sound for understanding the concepts.
The purpose of this lesson is to demonstrate the importance of a 30-60-90 triangle. The student should have some prior knowledge of an equilateral triangle. This will be the focal point of the lesson. Giving the students time to explore an equilateral triangle. The purpose for this is to allow the student time to reflect and note that if you split the triangle in half, there will be two triangles. They both will be a reflection of each other, with the same angles of measure. In other words they will be mirror images of themselves. Once the students realize this. We will continue to analyze the 30-60-90 triangle. Determining leg lengths and angles of measure.
The only technology that will be used is the internet and a calculator. The students should know how to use the square root function on the calculator. The calculator is important because irrational numbers will be used and it is the more efficient way to get an approximation of the number.
This will be a three day lesson an on the last day the students will be introduced to how to find the perimeter of the triangles using there knowledge of the 30-60-90 triangle.
There will be a quiz at the end of the lesson. This will be in the form of an on-line quiz. The students will be directed to a website to take it. My goal is that the students should be able to solve related problems with at least 85% accuracy.

Be sure to follow the rubric I provided - it asks for specific content and tech standards. As for assessment - be specific with how you will measure learning.
