Subject: Measurements and Geometry of Mathematics Grade I
Grade Level: Grade 1
Objective: Measurements of length and distance using non-standard units.,
Measure the length of an object and the distance between two objects using
non-standard units.
Learning within the curriculum:
1) Comparing lengths: Students learn to compare the lengths of various classroom
objects using their own hands or feet as non-standard units. This lesson connects to
the objective as it reinforces the concept of measuring length using familiar and
accessible units.
2) Estimating lengths: Students practice estimating the lengths of different objects
before measuring them using non-standard units. This lesson relates to the main
objective by encouraging students to think critically about length and develop
estimation skills before applying measurement directly.
Learning across the curriculum:
1) Science - Exploring Plant Growth: Students can measure the height of plants
using non-standard units like paper clips or blocks. This connects to the objective as
it provides a real-world application of measuring lengths and distances, reinforcing
the importance of measurement in understanding plant growth.
2) Art - Creating a Length Chart: Students create a length chart of their favorite
classroom items, measuring them with non-standard units like crayons or pencils.
This integrates measurement skills with artistic expression, showing how math
applies to creative activities.
Review Motivation:
[Teaching Strategy:] Interactive Quizzes
[Instructional Materials:] Rulers, various classroom objects
Engaging Activity 1 - Quick Draw: Students draw their favorite object and estimate
its length in non-standard units.
Engaging Activity 2 - Mystery Box: Students guess the length of an object hidden
in a box using their hands or feet as a measuring unit.
Engaging Activity 3 - Measure Me: Students partner up to measure each other's
heights using non-standard units, fostering teamwork and engagement.
Activity 1: Measuring Classroom Objects
[Teaching Strategy:] Cooperative Learning
Materials - Various classroom objects (books, pencils, erasers), non-standard
measuring units (paper clips, blocks)
Significance - This activity allows students to practice measuring real objects,
reinforcing the connection between math and everyday life.
Instructions -
1) In pairs, select three classroom objects to measure.
2) Use the non-standard unit (e.g., paper clips) to measure the length of each object.
3) Record the measurements on a chart.
Rubric
- Accuracy of measurements - 10 pts.
- Collaboration with partner - 5 pts.
- Neatness of recorded chart - 5 pts.
Assessment Questions:
1) What object was the longest?
2) How many non-standard units did you use to measure your favorite object?
3) Did you find it easier or harder to measure with non-standard units? Why?
Activity 2: Distance Between Two Objects
[Teaching Strategy:] Discovery Learning
Materials - Two distinct classroom objects placed at a distance apart, non-standard
units (e.g., string, blocks)
Significance - Students learn to measure distances, promoting critical thinking and
problem-solving skills.
Instructions -
1) Identify two objects in the classroom that you want to measure the distance
between.
2) Determine the distance using a non-standard measurement unit, such as blocks
or strings.
3) Share your findings with the class and discuss any differences in measurements.
Rubric
- Correct identification of objects - 5 pts.
- Accurate measurement of distance - 10 pts.
- Clarity of presentation - 5 pts.
Assessment Questions:
1) What was the distance you measured?
2) Did other groups measure the same distance?
3) How could you improve your measuring technique next time?
Inclusive Activity 3: Nature Walk Measurement
[Teaching Strategy:] Experiential Learning
Materials - None
Significance - Students will connect measurement to the natural world while
practicing their skills in an inclusive setting.
Instructions -
1) Go outside for a nature walk and identify various natural objects (e.g., leaves,
sticks).
2) Estimate the length of each object using your feet or hands as non-standard units.
3) Share your estimates and measurements with the group upon returning to the
classroom.
Rubric
- Participation in the activity - 5 pts.
- Accuracy of estimates - 5 pts.
- Sharing findings with the group - 5 pts.
Assessment Questions:
1) What object did you find that was the longest?
2) How did you estimate the length?
3) What did you learn from measuring in nature?
ANALYSIS:
Activity 1 - Students practiced measuring real-life objects, enhancing their
understanding of length. By collaborating, they developed social skills and learned
from one another.
Activity 2 - This activity encouraged students to discover measurement concepts
independently, fostering critical thinking as they compared their findings with peers.
Activity 3 - Engaging with the natural environment allowed students to apply their
measurement skills in a real-world context, reinforcing the objective of measuring
length and distance using non-standard units.
ABSTRACTION:
The ability to measure length and distance using non-standard units is essential for
grasping fundamental math concepts. Students learn that measurement can be
flexible, using various objects to quantify length. Understanding measurement
encourages exploration and application of math in everyday life.
Supporting Material 1 - "How Tall Is a Tree?" - This book explores various ways to
measure height using everyday objects, illustrating the concept of non-standard
measurement through engaging illustrations.
Supporting Material 2 - "Measuring with Objects" - This resource provides activities
and examples of measuring lengths using non-standard units, reinforcing the
importance of measurement in both math and real-life scenarios.
APPLICATION:
[Teaching Strategy:] Project-Based Learning
Task 1 - Create a mini-exhibit where students measure different classroom objects
and present their findings on a poster.
Task 2 - Organize a "Measurement Day" where students measure different items at
home and bring their results to share with classmates, promoting family involvement
in learning.
ASSESSMENT:
[Teaching Strategy:] Socratic Method
[Instructional Materials:] Measurement tools, chart paper
Question 1 - How can we measure something if we don't have a ruler?
Question 2 - What are some advantages of using non-standard units?
Question 3 - Can you think of a situation where measuring length is important?
H.O.T.S.:
Question 1 - Why might someone choose to use non-standard units over standard
units?
Answer 1 - Non-standard units can be more relatable and accessible for younger
students, fostering understanding without needing specific tools.
Question 2 - How does measuring with non-standard units help you understand
length better?
Answer 2 - It allows for hands-on experiences that make abstract concepts more
concrete and relatable.
Question 3 - In what ways does measuring length in nature differ from measuring in
the classroom?
Answer 3 - Nature provides a variety of objects and contexts, requiring students to
adapt their measuring techniques to different environments.
Assignment:
Assignment 1: Measurement Journal
[Guiding Overview for Teacher:] Encourage students to keep a journal of
measurements taken at home, using non-standard units to foster continuous
learning.
[Assessment Question:] What lengths did you measure, and what non-standard
units did you use?
Assignment 2: Family Measurement Project
[Guiding Overview for Teacher:] Have students engage their families in measuring
various household items using non-standard units, promoting collaboration.
[Assessment Question:] Choose three items from your house, measure them with
non-standard units, and share your findings in class.
