For my lesson plan analysis I chose
a lesson plan titled "Fill 'Er Up" that involved teaching students
about volumes of rectangular prisms for a few reasons. First and foremost I
chose this particular lesson plan because I believe that the core standard it
focuses on is what a lot of people say is wrong with math education nowadays.
That is, that we are educating students to pass tests and not giving them the
skills outlined by CCSS.Math.Practice.MP4,
which states that we must teach students to be able to model everyday problems
with mathematics and CCSS.Math.Practice.MP2, which focuses on the relationship
between abstract mathematics and quantitative mathematics. On top of this, I also chose this particular
lesson plan because its use of technology, which I felt was forced and only
detracted from the goals of the teacher.
The
goal of the lesson plan was to teach students about a fundamental skill that
pertains to their everyday life, while also teaching them about the ideas of
volume, space, and quantity, but to do so by lecturing and having them use a
program that worked in abstract quantities. By doing so the plan fails to meet
the standard outlined above because the students are unable to, "interpret their mathematical results in the context of the
situation and reflect on whether the results make sense" (Standards for Mathematical Practice). One way to improve on this would be to start of the lesson
with a student centered Q and A session as opposed to a lecture and teacher
centered Q and A session. By allowing students to ask questions that they may
have about definitions of height, length, depth, and volume and allowing them
to define the concepts themselves the lesson become more aligned with the core
standard as well as an additional standard CCSS.Math.Practice.MP6 which focuses on meanings of units and clear
definitions of concepts.
This
standard is further aligned with the plan with the removal of the technology it
recommends, which seems unnecessary, and actually detracts from the lesson plan.
The applet recommended for use, serves little purpose as it is something that
is easily modeled with real world examples, is time consuming, as even I was
confused as to how the applet worked and what it was trying to achieve, and
deals exclusively with abstract units. By removing the use of the applet, and
instead using a shoebox with number cubes, students can use the definitions
they defined at the beginning of class to measure the length, width, and height
of the shoebox, as well as the real world measurements of the number cubes, to get
a better understanding of what exactly volume is and how it is measured and
recorded and further align the lesson plane with all standards detailed above.

I agree with you, lecturing is not the best way to go about teaching students new concepts. I like your solution to this where the students ask questions. Students will most likely have a better understanding if they have the opportunities to ask questions on why they are puzzled. In addition, before learning how to find the height, length, depth, and volume the students need to have a clear understanding of the definitions, so it is important that they ask questions if they do not understand the definitions. Another idea would be having students work together to come up with definitions, so they could bounce ideas off each other.
