Materials:
Alabama Course
of Study: Mathematics, page 25,
number 38,
Children’s literature: Weight,
large book, small book, bowling ball, two plastic pins and bowling ball, golf
putter, golf ball, two plastic golf putters, hockey puck, baseball, q-tip,
guitar pick, paper clip, sunflower seed, stuffed toy, wrench, hammer, plastic
hammer, child’s nail table, big shoe, flip flop, scale, two staplers, two glass
jars, water
·
Objectives: The students will:
·
(Application)
distinguish the difference between pounds and ounces.
·
(Comprehension)
arrange manipulatives from lightest to heaviest.
·
Grade Level: Second Grade
II. Orienting:
·
Anticipatory
Set: The teacher
will take the children out to the playground and gather them around the
seesaw. The students will get on the
seesaw two at a time to compare each other’s weight. The students can also try to balance with
each other. The students can compare their
weight to the teacher’s weight.

·
Purpose: The teacher will say, “The purpose of this lesson is to
enable you to feel the difference between heavy and light objects. After today’s lesson, you will be able to
decide whether an object weighs pounds or ounces.”
·
Connection to
previous/Build background knowledge:
The
teacher will say, “I know all of you can tell if an object is heavy or
light. Today we are going to learn if an
object is pounds or ounces.”
III.
Presenting:
·
Teaching Procedures:
·
The teacher will demonstrate the difference between
pounds and ounces using objects of various sizes (i.e. staplers, books, and
balls).
·
The teacher will show the book Weight to the
students and discuss certain aspects.
·
The teacher will demonstrate how a balancing scale works.
·
The students will have an opportunity to work with the
scale using the various objects.
·
Review:
·
(Application) The
teacher will ask a volunteer, “Which weighs more, an ounce or a pound?”
·
(Comprehension)
The teacher will ask the students to put manipulatives in order from
lightest to heaviest.

·
Guided
Practice:
·
The teacher will direct the students’ attention to two
glass jars filled with water.
·
The students will take turns dropping various objects
into the water simultaneously and discovering which object will hit the bottom
first.
·
Independent
Practice:
·
The students will put various objects in order from
lightest to heaviest.
·
The teacher will be observing for comprehension of the
concepts.
·
Summarizing:
·
The teacher will say, “Today, we have compared the
differences between pounds and ounces and heavy and light. Tonight, I want you all to go home and select
a small object to bring to school tomorrow.
We will continue the lesson by racing our objects in the glass jars
filled with water.”
The teacher will make
note of each child and his or her success with the independent practice
activity. For enrichment, those
students will begin to estimate how many pounds or ounces a certain object may
weigh (i.e. bowling ball, book, stapler). Those students will then check their accuracy
with a scale. For remediation,
those students will continue to feel the difference between heavier and lighter
objects (i.e. paper clip, baseball, hammer) using their hands. Those students will then try to put them in
the correct order from lightest to heaviest.
