Many
students struggle to grasp the concepts and applications of rational numbers.
Although every school covers these topics in their math curriculum, I find that
students are immediately detoured from a math problem that they would be able
to solve with integers because the rational numbers are ‘scary.’ This is why I
choose to work with a lesson plan teaching students to solve expressions with
rational numbers. The lesson should last about 5 days, depending on the comprehension
of the students. The teacher may expand the lesson and provide more examples
for any given part to ensure student understanding. Unfortunately, the lesson
plan is not available online because I received it as a written page from my
Inclusion professor last semester. It is imperative that students grasp the
concepts of rational numbers because they will not only be found throughout the
rest of the students mathematical education, but will also surround them in the
real world. Throughout the post, I will be providing explanations for the technologies and strategies listed in my Technology Integration Plan Matrix.
The lesson
begins with the teacher giving a brief lecture and presentation providing
students with the instruction and rules on applying operations to expressions
with rational coefficients. During the lecture, the teacher will use the
whiteboard to show students how to compute the calculations by hand. The
students will follow along at their seats and provide their calculations’ in
comparison with the teacher’s. Afterwards, they will break into small groups and
discuss how they would solve a given set of problems and work through their
calculations. The calculator will be provided at the end of the group work for
students to evaluate their own calculations. This will provide them the
opportunity to visually see that the numbers that they computed by hand are
equal to their decimal equivalents.
During the
next topic, students will practice reorganizing problems to figure out what
operation will be needed to solve. The teacher will post a different problem on
the projector. The students will analyze the problems as a group and decide how
they will rewrite the problem. They will write their response on the hand-held
white board. The class will all hold up their answers and then have a group
discussion answering why they chose to answer the problem this way and how it
makes the solution more clear. The teacher may also shed light on how they
could come to these decisions and why it will help them.
The next part
of the lesson, students will work together to solve multi-step problems
involving rational numbers. Students will be completing a comprehensive
worksheet that will allow them to organize rational numbers that are equivalent
in different forms, and use them to solve problems. This worksheet will be collected
by the teacher to provide a formative assessment of the student’s learning
progress. Students will have calculators to help them see the equality of the
different forms of the calculations and how they are equal. It will also
provide a great opportunity for students to check their work.
During the
following activity, students will analyze real world problems and decide how
they will create the equations used to solve them. They will decide how to
solve the problems and will work together to discover the best answer. Students
will use the graphing software to create graphs of these equations and show
their solutions visually. They will then share their answers with the class and
discuss what decisions they made and what problems arose while deciding how to
answer this question. The teacher will chime in to provide guidance to ensure
students find correct solutions.
The final
assessment to this lesson will be a homework assignment that will involve
students answering a real world problem. They will work individually to solve a
real world problem. While solving this problem, they will utilize all of the skills
learned above to create a solution. They will then create a graph of the
inequality using a computer graphing software. They will infuse this graph into
a word document. In this word document, students will defend their answers and
verbally explain how their answer is correct and what it means in relationship
to the question asked. This assignment will serve as an assessment of learning
for the lesson.
Although the
majority of the technologies in this lesson are not on the cutting edge of the
technological advancements, they all provide an enriching purpose in the sake
of the lesson. Students will be able to use these technologies in order to accurately
visualize and conceptualize the topic at hand.
