Lesson 4
Title: Lighthouse Geometric
Grade Levels: Third / Fourth
Subject: Math
Learner Outcomes:
Students will:
-
recognize and be familiar with
characteristics of various geometric shapes.
-
recognize geometric shapes in objects
found in their environment
-
use their knowledge to construct
a model of a lighthouse.
-
demonstrate their knowledge of using
coordinates by graphing points to produce a picture.
-
demonstrate their ability to use programs
using the draw tool if session three is to be completed online.
Time Frame: Three 45 minutes lessons.
Additional time will be needed for construction, this will depend on the
extent of the project and ability of group.
If students complete session 3 individually
online, the time allotted will be determined by the number of computers
available. The completetion of this lesson could be done as a station
activity.
Materials:
-
Sheets to review geometric
shapes.
-
Materials students select for making
model of lighthouse, suggested materials include salt, paper cups and trays
or plates, plastic wrap, cardboard tubes, tape, paste.
-
Pictures of lighthouses, either hard
copies or use the Internet to find pictures. Various sites are listed
throughout the unit or refer to the Reference
page.
-
Copy of graphing paper and list of coodinates
(Level 1 or Level 2),
math materials for adopted curriculum, pencils.
Technology Tools/Courseware: Internet
for obtaining suggested worksheet and to view sites with information on
lighthouses, draw program such as one found on Microsoft word.
Teacher Notes: This is a lesson that
students can go into detail with or do very simply, the decision on the
amount of time will depend on the teacher's purpose.
Session 3 has two different levels
of worksheets available, choose the one appropriate for the students' abilities.
(Level 1 or Level 2)
Procedures:
Session 1
-
Review with students the types and characteristics
of geometric figures appropriate to grade level. See Geometric
Shapes for patterns for making solids
and review of worksheet for geometric shapes.
-
Have students make a list of all the
places they can find geometric shapes in nature and in things that they
use or see in everyday life. This could be done in cooperative groups.
The lists would then be shared with the class and one list compiled. Students
could be given the option to add to this list as they find more objects
with geometric shapes.
Session 2
-
It is recommended that students complete
these activities in cooperative groups with each student being given the
opportunity to bring their ideas to the project.
-
Show the students pictures of lighthouses
and the keeper's home. This could be done by giving the students
hard copy pictures or allowing them to visit various Internet sites to
find pictures and descriptions. Have students name all the geometric shapes
they can identify on these pictures. Make a list of the shapes and
what part of the lighthouse or keepers house they make up. Help students
identify if shapes represent plane or solid shapes.
-
Using the list compiled the previous
day and any new items the students think of, have students select items
they could use to construct a lighthouse scene.
-
Gather materials and construct models.
-
Possible materials for construction of
models could include:
Salt dough for base or land
Large sturdy paper plate or platter to be used for the base.
Large cup for base of lighthouse.
Cardboard tubes for lantern section.
Cellophane or plastic wrap for use in window panes if these are to
be cut out.
Cellophane or plastic wrap could be crunched to represent waves
on the shore of the beach.
Milk or juice cartons for lighthouse keeper's house.
Center layer of corrugated box to represent logs or house roof.
Session 3
Procedures:
-
Teacher will select Level
1 or Level 2 of Coordinate Worksheet.
-
Teacher will teach or review material
on coordinates, making sure that students understand when points are plotted
the first number represents the numbers going across often referred to
as the x axis and the second number represents to y axis or the one going
up and down. Over and Up
-
When students have demonstrated an understanding
they will be told to complete the prepared worksheets. There are
two worksheets prepared on two different levels. These sheets and
the directions may be printed off so that each student my have a hard copy
to work from.
The task may also be completed online.
The graph paper and directions may be copied to the students folders to
be done and saved, or it may be completed at its location, not saving the
changes when the program is closed. The students can print off their
finished work or save it to their folders. Using the straight line
tool from a Drawing program such as on Microsoft Word, the pointer can
be placed on the location of the first number and dragged to the point
of the second number.
Modifications:
Students work in cooperative groups, being grouped to meet each students
special needs.
Session 3 has two levels of worksheets
available (Level 1, Level
2). Level one is prepared with larger grids and fewer numbers.
Enrichment Activities: The making
of the lighthouse model could be used as an enrichment activity.
Students may design pictures using
coordinates.
Evaluation/Assessment: Completion
of project. Teacher could grade on students’ willingness and success
in working in cooperative groups.
Quiz (http://www.quia.com/t/102172.html
) on matching the definition and name with the correct shape.
Accuracy in completing the coodinates
worksheet may be used as an evaluation tool.
