LESSON PLAN #1

Unit Title: Angle Me This, Angle Me That
Math Standard: Measurement
Math Indicator: #7 Use benchmark angles (e.g., 45, 90, 120) to estimate the
                    measurement of angles, and use a tool to measure and draw angles.

Objective: Each 5th grade mathematics student will create benchmark angles and use them to find benchmark
angles in objects around them. Benchmark angles used are 45, 90, 120, 135, and 180.

Materials:
 Straight edge for each student
blank paper
*** MUST BE PREPARED AHEAD OF TIME:
                - 5 coffee filters per student (prefold one filter per student into thirds)
                - wall chart that is a replica of the student chart (in attachments)
crayons or markers
chart paper
chart markers
copy of student benchmark angles chart for each student (in attachments)
copy of activity paper for each student (in attachments)

Procedures:

    1. Identify today’s goal: to discover the measurement of several special angles, which shall be called
       benchmark angles. These benchmark angles will be used to estimate the measure of other angles.
       (Benchmark angles can be defined as easy to identify reference angles used to estimate unknown
       measures of angles.)
    2. Pass out one coffee filter. Fold it in half and then in half again. (fourths) Unfold.
    3. Teacher can use a folded coffee filter or circle on board as model. Ask the students to tell you how
       many right angles they see. (4) Tell the students that there are 360 in these four angles. (360 in a
       circle) If these four angles’ measurements total 360, how much would just one right angle measure?
       (90…360/4=90) This is the first benchmark angle. Have students use a marker and straight edge to
       draw on two of the fold lines to create a 90 angle. Have them mark it 90. Put in a vertex also. As you
       add information to the wall chart, have students add information to their personal chart.
    4. With another coffee filter, have the students fold them in half and then half again. Do not unfold.
       Review where the 90 angle is. Pose the question: if we fold the 90 in half, what will we create?
       (another angle, a 45) Have students fold the filter in half. This is the second benchmark angle. Have
       students unfold the filters and use their marker and straight edge to draw on the two fold lines that create
       the 45 angle. Create a vertex. Label the angle with 45. Add the information to the wall chart as
       students add to their own charts.
    5. Using a third coffee filter, see if students can fold it to create a 90 (right) angle. Have students help
       each other. Pose this question: if you unfold the paper once, what have you created? Some students will
       say a straight line. Have them discover that it is indeed an angle by reviewing the definition of an angle
       (the intersection of two rays – center of the circle is vertex of angle, rays come out from that point….in
       opposite directions). Ask what would be the measure of this angle? (180) This is called a straight
       angle, and it is the third benchmark angle. Have students trace over the folds that create this angle, make
       a vertex, and label the angle 180. Add information to wall chart.
    6. Use a fourth filter. Have students fold to create a 90. Then fold to create a 45 angle. Unfold the filter.
       On your model, go over the lines that will create a 135 angle (hint: 90 plus 45). Have students do the
      same. Ask what the measure of this angle might be? (135). How did they get their answer? Create the
      vertex and label it 135. Add the information to charts.
   7. Pass out the last filter which should be the one you have already folded into thirds. With a partner or in
      small groups, have the students try to come up with a measure of one of the three angles created. (60)
      Two of the angles? (120) Discuss answers and how the students got the answers. This is the fifth
      benchmark answer. Have students trace fold lines to create a 120 angle. Put in a vertex and label the
      angle with its measure.
   8. Optional activity: Using their benchmark angles as models, have pairs of students find objects in the
      room (hall, building) that have angles with these measures. Discussion afterwards would include which
      benchmark angles were easiest to find, which were hardest to find.

 Product:
  Student will have coffee filter models of five benchmark angles and a chart with
  benchmark angle information.

   If optional activity is done, students will also have a list of real objects that have
   angles with benchmark measures.

Assessment Criteria:
       As students are working with coffee filters, teacher should observe the answers that are produced and
the explanation of how they got the answers. Charts can be collected to check for accuracy. Teacher can also
show unmarked models to class or individual students for them to say which benchmark measure it is.

Attachments
Chart instructions: List angle measures from smallest to greatest. Type of angle: acute, right, or obtuse. For the
“see it”: students can place folded angle in box. Trace just as much will fit in the column.

LESSON PLAN #2

Unit Title: Angle Me This, Angle Me that
Math Standard: Measurement
Math Indicator: #7 Use benchmark angles (e.g. 45, 90, 120) to estimate the measurement of angles, and use a
tool to measure and draw angles.

Objective: Each 5th grade mathematics student will use benchmark angles to estimate the measurement of
angles.

Materials:
 3” by 5” cards – 5 per student
 straight edge
 piece of paper

Procedures:
   1. Using a straight edge each student should draw 5 angles, one per card. The angles need to be either
      acute or obtuse. The angle should be marked on the card. On the back of the card, students should put
      their name and labeled 1-5. On a separate piece of paper, each student should create an answer key
      containing an estimate of the angles’ measurements they drew and the benchmark angle he/she used to
      help them estimate. They should be prepared to explain their estimate and use of benchmark angle.
      Teacher should walk the room and check students understanding at this point, by asking them to orally
      explain one of their angles and their estimates. (15 min.)
   2. In pairs, the students take turns estimating each other’s angles. After each estimate, the students should
      also offer an explanation using a benchmark angle. If there is a question about a student’s answer or the
      student’s answer key, they may use another pair of students as a resource. If there is still a
      disagreement, the teacher may be consulted. Teacher should walk the room and listen in to students’
      estimates and explanations. (15 min.)
   3. After students have had a chance to practice estimating, pick some angle cards from the class that are
      examples of estimating with each of the benchmarks. Discuss as whole class. (10 min.)
   4. Use student work sheet for individual check on student understanding of this objective. (See
      attachment)

Product:
       - Student made angle cards.
       - Individual student assessment

Assessment Criteria:
      Teacher observation and questioning of student activity to check for understanding of the use of
benchmark angles to estimate angle measure.
      Individual student assessment rubric:
             3: Student chooses a benchmark angle and correctly explains how it was
                  used to arrive at the estimate.
             2: Student chooses a benchmark angle, but explains his/her estimate with
                 some difficulty.
             1: Student chooses a benchmark angle, but cannot explain his/her estimate
                 relationship to the benchmark.
             0: No understanding of the relationship between estimating angle
                  measure and the use of benchmark angles.
