GRAPHICS, EDITING AND FORMATTING BY: Dr. Beth McCulloch Vinson
I. Preparing
Materials:
Objectives: The
students will:
(Knowledge) recognize and call by name the following geometric shapes: triangle, quadrilateral, pentagon, hexagon, octagon, nonagon, and decagon;
(Synthesis) work with manipulatives to reinforce
understanding; and,
(Application) create polygons with various angles
to display their knowledge of the different types of angles.
Grade
Level: 3
II. Orienting
Anticipatory Set:
The teacher will talk about the different shapes we see every day and
how each one has certain characteristics.
Purpose:
The teacher will explain that the shapes in our world often have special
and important jobs and that it is important we are able to recognize those
shapes.
Connection
to previous learning/Build background knowledge:
The teacher will explain that the previous lessons have been about the
basic shapes. She will explain that we
will use that knowledge to better understand how the shapes are different.
III. Presenting
Teaching Procedures:
The teacher will give each child a geoboard and a geoband.
The teacher will begin to read The Greedy Triangle by Marilyn
Burns.
As a new polygon is mentioned, the children will form it on their geoboards.
After a new shape is formed, the teacher will ask how many sides there are and
how many angles it has.
When all the students have created their pentagon, the teacher will ask,
"What do you notice about the angles on the pentagon you just
formed?" (Synthesis)
The teacher will point out that there are angles larger than
90.
The teacher will tell the students these are called obtuse
angles.
IV. Practicing
and Summarizing
Review:
We have learned a lot about the different shapes around
us! (Application)
We learned that they have different numbers of sides. (Application)
We learned that they have different numbers of angles and
different types of angles.
Guided
Practice:
The students will make the shape on their geoboards that the
teacher makes.
They will tell the teacher what the name of the shape is.
They will tell the teacher how many sides the shape has.
They will tell the teacher how many angles the shape has.
They will tell the teacher what kind of angles the shape has.
Independent
Practice:
In groups, the students will draw on large poster boards an
assigned shape.
They will write its name, the number of sides, the
number of angles, and how many angles the shape has.
These posters will be used to decorate the classroom for the students'
reference in the future.
Summarizing:
Let's see what you have learned! "What is the name of a polygon that has
six sides?" (Hexagon) "How many sides does it have?" (Six)
"How many angles does it have?" (Six)
"What kinds of angles does it have?" (Obtuse)
"Why are they called obtuse angles?" (They are greater than ninety degrees.)
V. Assessment:
The students will
individually draw two polygons. The polygons will be chosen by drawing
two cards out of a basket with the name of a polygon on each card. The
student will use graph paper and a straight edge to draw these. Beneath
the drawing, the student will write the name of the polygon, how many sides it
has, and, what kinds and how many angles it has.
