Observation Lesson Plan
Name: Elizabeth Soricelli
Grade: First
Topic/Purpose: Math: Using Units to Estimate and Measure Length
Date: June 1st, 2015
New York State Standards:
CCSS.MATH.CONTENT.1.MD.A.1 Order three objects by length; compare
the lengths of two objects indirectly by using a third object.
CCSS.MATH.CONTENT.1.MD.A.2Express the length of an object as a
whole number of length units, by laying multiple copies of a shorter object
(the length unit) end to end; understand that the length measurement of an
object is the number of same-size length units that span it with no gaps or
overlaps. Limit to contexts where the object being measured is spanned by a
whole number of length units with no gaps or overlaps.
Learner Outcomes: (Objectives)
Students will define and identify nonstandard units of measurement.
Students will estimate lengths by using a nonstandard unit.
Students will measure lengths of objects by using a nonstandard unit of
measurement.
Students will compare lengths by using a nonstandard unit of measurement.
Materials and Resources:
Smartboard
Linking cubes
Tiles
Paper clips
Counters
Pencils
Measurement sheet
Instructional Plan:
Introductory Strategies and Activities:
The teacher will begin by having students describe what they know already about
length and measurement. Students will share what they know and any
misconceptions/questions they have. Students will then watch a brainpop video (3
minutes) about length and measurement. The teacher will explain that you can use
standard units of measurement, like rulers, or nonstandard units of measurement, like
crayons, to measure the length of an object. The teacher will explain that when you
estimate a measurement, you are making an educated guess, like a hypothesis, about how
long you think the object will be. The teacher will model how one can measure an object
with a nonstandard unit of measurement. 10
Developmental Strategies and Activities:
Students will work in partners/groups to determine the lengths of items around the
room by using nonstandard forms of measurement. Students will first pick a tool of
measurement. Students will choose different objects and estimate the lengths, then
measure the lengths, using nonstandard uses of measurements. Students will then
compare the lengths of each object. 10
Concluding Activities:
To conclude the lesson, students will compare the lengths and measurement tools
of objects with other groups in the class. Together they will determine which items were
longer or shorter and which tools were longer or shorter. Students will reflect on the
process and how it worked. 5-10
Differentiated Instruction:
This lesson has students doing a wide variety of tasks, thus allowing students who
learn differently to have the chance to shine. Students will watch a brainpop video and
brainstorm answers. Students will use manipulatives and concrete objects to measure.
Students will sit together to provide support. Students will use the Smartboard to
differentiate.
Assessment:
The teacher will circulate as the class works. The teacher will collect the
measurement page to assess. Students will also complete graded homework assignments.
Follow-up:
For homework, students will complete a measurement comparing activity.
