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.

Purposful Planning: Quagmire
There is much to be said about people who take responsibility for their actions, and not blame others for their shortcomings. Mature people understand that they have the ability to take control of their lives. A mature adult with a family has to take charge and set boundaries(rules and regulations) for their off springs. It should be understood that it is the responsibility of the parent to police their children.
Parenting is not the responsibility of the school. The school is for educating children as they develop into adulthood to become productive citizens of society. Parents can't expect the school to provide all the needs of their children. They have to instill decent moral values in their children.
The school can inform parents and students of things such as sexting and cyberbullying, however once they are made aware it is their responsibility to use prudent discretion. They should report such incidents to authorities. Parents who are aware or suspect these acts are happening, should get involved especially if their child has knowledge of or is a victim.
Why is this happening and the students understand the seriousness of these crimes. I think the answer is in the way adolescents brain function. There is proof through recent research that adolescents continue to take risk, because there is something in the brain that gives them a sensation and its gratifying to them. Its like dopamine when we laugh, it triggers the brain to want more.
Having knowledge of this research can help us understand why they continue to take part in such acts. This should not be and excuse to let them off easy, because the victims suffer irreparable damage they will be with them for life. Sometimes causing death by suicide. Although we understand what triggers adolescents to continue to partake in these nonsensical acts, it should not lessen the consequences. In fact it is my opinion that stiffer punishment be administered for anyone involved in such crimes. I think that the parents should take some responsibility especially if they have seen signs relative to these acts.
Technological advances while good have placed great demands on parents and schools. We known have to watch for cell phones, ipods, and PS2's, which takes valuable time away from teaching. I think laws need to be enacted to effectively deal with all these, 21st century technological gadgets.
