In technonogy fractions are used all the time. Knowing how to reduce them makes life a lot easier when working with rulers. Students need to know how to reduce fractions. You knew your subject matter and were able to explain ur topic logicaly. Showing the steps by the white board was good you took your time to explain each step.

Everything was explained in a logical sequence. You presented two methods to accomplish the same thing, one which I had not remembered. I believe presenting multiple means of solveing any problem, instead of having some students struggle with only one method is a great way to reach more of the students in your class. Good approach, nice video.

Very nice instructional video! You met the learning objectives by completing step by step the fraction. This video clip could be used in all types of lessons related to fractions in different subject areas too! Great intro and ending. Fun blogging experience! Good work!

Critique:
This video clip matched with the learning objectives of the lesson unit by breaking down concepts of fractions in math that some high school students may find difficult to understand, into easy steps. You used visual literacy, which I believe is the best way to show students how to understand math (especially since I have never been exceptional in this subject). I can see how fractions could be used to instruct their purpose in everyday life, such as in measurements for cooking/baking, in science with graduated cylinders, and even in art when using proportions for drawing figures or objects. If I were the instructor, I would create another video clip for the first three objectives of the unit plan, which pertained to discovering problems and solutions in daily life, by the use of fractions. Maybe by providing a video clip with pictures or other videos of areas of life where these problems and solutions would occur, students coluld develop an even greater interest for learning about fractions and the importance of them. I think that this particular video clip was well-presented, and the goals and objectives were concise. Kristen showed the process of reducing fractions thoroughly, while speaking clearly for anyone to understand. In addition, this video clip has a few different positive significant features. The music in the beginning of the video would capture most students' attention right away. Every step of reducing fractions was clear and organized through thought and process. I thought the best part was that she included additional graphics and text on top of what she wrote on the dri-erase board, just to emphasize each particular point, or step. It kept me focused and my thought-process was controlled, rather than sporadic. It also made it easier to see each concept in reducing fractions, in case I was confused or unable to read what she was writing and drawing on the dri-erase board. Although, I would never plan on teaching math in my lifetime, theoretically I would definitely adopt this unit plan and video clip to teach my students. The video clip would be an extremely useful vice for building student comprehension in logic/rational skills. If she can make math seem at least somewhat interesting and simple to learn for someone like me--who is predominantly right-brained--then she knows how to effectively teach her content area to students. Thank you for sharing your video!
