Summarizing Strategy:
1.
Using
a ticket out the door, have students complete the following prompt:
a.
1
thing you learned today
b.
1
thing you are still struggling with
Homework Assignment:
Students must complete the remaining
questions on the 5.1 worksheet for the following day.
Reflection:
Overall, the lesson went well! The
students responded to the Simon Says game, and I was able to formatively assess
the student’s knowledge from the previous class. I must have done a good job
teaching this concept because every single student was able to identify the
different types of angles. Additionally, I believe that offering sample writing
from the class was very beneficial because everyone was able to see what his or
her classmates were capable of doing. One thing I would change about this is
referring to the student as simply “student.” During my explanation, I referred
to the student writer as a “her” and it was then easy for the others to
pinpoint whose writing assignment it was. I know that the work was being
praised, but I didn’t want to embarrass the specific student or make him/her
feel bad.
One thing that I would change is
training the students to be prepared for a starter during every class. If this
was my classroom, I would like to emphasize how important it is not to waste
class time, and it often takes several attempts to get the class focused after
7th period resource. Also, the class period was shortened because of
report card distribution, and I was not able to finish the entire lesson as
planned. One thing that I would like to work on is timing during a lesson.
Sometimes I struggle with trying to figure out how long a specific activity
will take. Lastly, I think that I didn’t assign enough practice problems
because many of the students were finished with the assignment before the class
was over. If I was able to, I would have assigned another worksheet for
homework to ensure that students understood how to measure angles and label
them accordingly.

Reflection:
Station 1
Directions
1.
Take the pile of angles and group them based on type. For example, all of the
acute angles should be in one pile. Once completed, have your group leader
ensure that all of the answers are correct before moving to step 2.
2.
Once your group has successfully classified the type of angles, each one of you
will pull a note-card from the pile. On the note-card, you will find an angle
measurement. On your whiteboard, draw the angle. When all members of the group
are completed with this task, pass the whiteboards to the left.
3.
Measure the angle on the whiteboard you have been passed. Write the angle on
the whiteboard and give it back to the original owner. Was the angle correct?
If not, try again.
Station 2
Directions
1.
Look at the pictures of angle relationships with your group mates. Classify the
different pictures based on the type. For example, all of the vertical angles
should be placed into the same pile. Once completed, have your group leader
ensure that all of the answers are correct before moving on to step 2.
*** Supplementary angle
relationships and adjacent angle relationships can be the same!
2.
Each student in your group should take a worksheet and complete it to find the
missing angle measurements without
a protractor. Once completed, compare your answers with another person in your
group.
Station 3
Directions
1.
As a group, pick from the collection of data tables and answer the following
questions as a group.
i.
How
many total people were surveyed?
ii.
What
is the fraction for each possible answer?
iii.
What
is the decimal for this fraction?
iv.
How
do you find the angle measurement?
2.
Once you have answered the following questions, draw a circle graph
representing the collection of data. Be sure to label the graph and each piece
correctly. Everyone should be involved in drawing an angle!
3.
As a group, write a brief 3-4 sentence paragraph describing the data in your
circle graph. You may write this directly under the circle graph.
Station 4
Directions
1.
Each member of your group should take a piece of graph paper. On the graph
paper draw the x and y axis and create a scale for each line labeling it
correctly. For example, the scale may go by ones, twos, fives, tens, or
hundreds.
2.
Randomly plot 6 points on your coordinate grid.
3.
Pass your coordinate grid to the person to your right.
4.
Once you have been given someone else’s graph paper, write out the points in
correct format.
