Lesson Plan #: AELP-MEA0005

## Making Estimations in Measurement

An Educator's Reference Desk Lesson Plan

AUTHOR: Debbie Ballard, The Community School, Ketchum, Idaho

Date: 1994

Grade Level(s): 1, 2

Subject(s):

• Mathematics/Measurement

OVERVIEW:

Children at this age will have difficulty in making accurate estimations in many areas of the curriculum. It is oftentimes hard to visualize a particular size much less know what the correct corresponding measurement would be.

PURPOSE: This particular activity was designed to provide students with an opportunity to utilize their knowledge of measurement in making accurate measurements and estimations.

OBJECTIVES:

Students will be able to:

• Read a story and participate in a discussion about size, measurement and giants
• Review the lines and numbers on the centimeter rod and tape.
• Make estimations of what they think their:
a. height would be.
b. circumference would be.
c. length of foot would be.
This information will be recorded on a graph.
• Take measurements of their own height, circumference and length of foot. This is to be done with a partner.
• Make estimations of what they think a giants:
a. height would be.
b. circumference would be.
c. length of foot would be.
This information will be recorded on a graph.
• Some students will estimate how many footsteps it would take their giant to walk to various locations throughout the school. (example; how many footsteps to the office, community room or to their science room)
• Some students will draw and paint a giant using estimated measurements.
• Some students will write a story about a giant.

TEACHER MATERIALS:

• big book entitled Jack and the Beanstalk
• Chart paper

STUDENT MATERIALS:

• centimeter rods and tapes
• butcher paper
• construction paper
• pencils
• paints
• scissors

ACTIVITIES AND PROCEDURES:

• The teacher will begin the lesson by reading with students the big book entitled Jack and the Beanstalk.
• Teacher and students will share in a discussion about giants, the concept of size, measurement and making estimations.
• Students will make a chart with their teacher where estimations are recorded. This chart will make estimations of what they think their height, circumference, and length of foot will be.
• Students will review the use of a centimeter rod and tape.
• Students will work with a partner and use centimeter rods and tapes to measure each others height, circumference and length of foot.
• Students will return to a discussion group and talk about their actual measurements and their estimations.
• Students will then make a chart with their teacher where estimations are recorded. This chart will make estimations of what they think a giants height, circumference, and length of foot will be.
• Students will then break up into small groups and proceed with one of the following activities:
1. Making a giants foot from construction paper and discovering how many foot lengths it takes to go to various locations in the school.
2. Making a giant using estimated measurements. Students will draw and paint their giant on a large piece of butcher paper.
3. Writing a story about a giant.

These lesson plans are the result of the work of the teachers who have attended the Columbia Education Center's Summer Workshop. CEC is a consortium of teacher from 14 western states dedicated to improving the quality of education in the rural, western, United States, and particularly the quality of math and science Education. CEC uses Big Sky Telegraph as the hub of their telecommunications network that allows the participating teachers to stay in contact with their trainers and peers that they have met at the Workshops.
