| Compare Length,Estimate and Measure Length |

2. Content-
|
| Long, longer, short, shorter, tall, taller |
| |
|
3. Goals: Aims/Outcomes-
|
TSW be able to estimate and measure length in nonstandard units.
TSW be able to compare lengths of objects with the words, long,longer,
tall, taller, short, and shorter. |

4. Objectives-
|
GLE 0006.4.3 Compare and order measurable attributes of objects
directly (by comparing them with each other) and indirectly (by comparing
both with a third object).
0006.4.7 Make direct and indirect comparisons between objects (such
as recognize which is shorter, longer, taller, lighter, heavier, or
holds more). |

5. Materials and Aids-
|
| Pencil, math book, cubes, classroom objects, pencil, practice page
11.4, basket of items |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
|
TTW have students take their cubes out of their baggie and make
a cube train with fewer than five cubes and then a train with more
than five cubes. TTW ask the students to compare the cube trains.
TTW introduce estimating. TTW ask the students who knows what the
word estimate means. TTW explain that estimate means to guess. TTW
hold up an object and have the students estimate how many cubes
are needed to measure the object. Then ttw measure the object to
show the students if there were correct with the estimation.

|
|
B. Development-
| TTW have classroom items such as a paper clip,glue stick, eraser,
paintbrush and pencil. TTW have students compare the objects to a
five cube train. TTW hold up an object and have students compare its
length to the cube train. TSW evaluate and state which is longer,
taller or shorter. TTW model how to estimate how many cubes to use
on an item. Then ttw will model measuring using the cubes on the item. |
| |
|
|
C. Practice-
|
TTW have students open their math books to page 205-206. TSW will
name and compare each item. TSW evaluate how they are different
and alike. TTW have students circle the taller item and underline
the shorter TSW do the same procedure by circling the longer item
and underlining the shorter.
TTW have a basket of items on each table. TTW have students pull
out an item and estimate as a group how many cubes are needed to
measure the item. Each group will share what their estimation is.
Then ttw have the students measure their item with their cube train.
Again each group will share their measurement. TTW have students
complete this activity using different items in their basket.

|
|
D. Independent Practice-
|
TSW have a five problem worksheet where they will work on their
own to show their knowledge in comparing lengths. TSW circle the
taller or longer object and underline the shorter.
TSW take out their math books to page 211-212. TTW have the students
think about the length of the cubes to help estimate the length
of each object. TSW record their estimation. Then ttw have the students
take the cubes and measure the objects and record their measurements.

E. Accommodations (Differentiated Instruction)-
|
Students will be at a table of four during lesson and work. There
is at least one student designated at each table to help a student
that needs extra help.
Students that need extra help will have a designated "buddy" at
their table that can help them.
|
| |
|
|
F. Checking for understanding-
|
TTW have students brainstorm places that have tables such as, desks,
cafeteria, library. TSW use body measurements and string to compare
and order the heights and lengths of these items. As a class we
will graph them on paper from shorter to taller.
TTW have students complete practice page 11.4 on estimating and
measuring length to check for understanding.
|
| |
|
|
G. Closure-
| TTW ask students to give examples of taller, shorter, longer with
tall, short and long. TTW have students state how we compared objects
today. To close the lesson ttw ask the students how do we estimate?
TSW say we think of the object and decide how many cubes are needed
to measure the object. |
