After learning about Madeline Hunter's lesson design it has helped to better understand how to write lesson plans. I think the hardest part for me to write would be the Bloom's Taxonomy. I think the main reason is because this information is so fresh and I had never heard of this part before this evening. 
This easiest part for writing a lesson plan for me I believe is the objective as I have really caught on to the ABCD way of thinking. I always go back and make sure that I have the Audience, Behavior, Condition, and Degree. This way of thinking of writing objectives has really helped. 
The most impactful part for the students would be the anticipatory set as this gets the students attention and helps to get them excited for the lesson plan. If we as teachers do not have the students attention and they are not wanting to learn then they are far less likely to catch on to the lesson. 
The parts that play a lesser part I would say would be the information at the very top: my name, class, duration, and then research based instructional strategies used. I think this information is not as important to the students as the rest of actually teaching the lesson and them getting a good understanding of what is being taught. This information is more to show the administration and other teachers.
