Overview: As part of the geometry unit, discuss
and look at examples of the different types of angles. After
learning the names of the geometric shapes students will learn
how to identify the types of angles and then complete the Kidspiration
activity, Identifying Angles.
Standards: Math, Grade 4, Geometry and Spatial Sense #2: Discribe,
classify, compare and model two- and three- dimensional objects
using their attributes.
Preparation:
· Load the Identifying Angles template on your computers
· Gather Materials: colored construction paper (3 sheets of different
colors per student), 1 rhombus, 1 square and 1 hexagon tracer
(1 set per table group)
Activity:
· Have student volunteers pass out materials
· Students cut out one of each shape using the tracer and paper,
each shape should be a different color
· Look at the different shapes and talk about the three types of
angles.
1. For right angles, look at the square and talk about how
the angles are all 90 degrees. Explain that they can use right
angles
to help determine what type of angle they are looking at when
they examine other shapes.
2. For acute angles, have students compare the smaller angle
on the rhombus with the angles on the square. Point out that
the acute angle is smaller than 90 degrees. Students can see
this by overlapping the two angles.
3. For obtuse angles, have students compare the angles on the
hexagon with the angles on the square. Point out that obtuse
angles are larger than 90 degrees. Students can see this by
overlapping the two angles.
·
Allow students time to look around the room for the different
types of angles (make suggestions on where they may find examples
i.e. the windows, desks, posters, pictures of other shapes in
their math books…)
· Explain the Identifying Angles activity to the students.
· Each student will complete the activity by sorting the shapes
pictures into the appropriate boxes.
·
Print each student’s work.
Assessment: Student must correctly place and name 12 shapes (75%).
(Placing shapes correctly in more than one box can be counted
or used as a bonus.)
