Stage 1: Identify Desired Results

State:	KS
Title:	Mathematics
Standard(s):	Uses appropriate vocabulary to compare two measurements: taller, shorter (height), hotter, colder (temperature), shorter, longer (length).

Understandings:
user	Measurement is important to everyday life.

Essential Questions:
User	1. Why do people need to know how to measure? 2. How does knowing how to measure solve problems and make ours lives easier? 3. Why is estimating height, length, and width important?

Knowledge and Skills:

K
Concepts of height, length, & width.

S
Measure to the nearest inch & foot.
Estimate height, length, & width of objects.

Stage 2: Determine Acceptable Evidence

Assessment Summary:
The class will read the book "Inch by Inch" by Leo Lionni. They will discuss how the inch worm measured parts of the animals in the book, such as the robin's tail, flamingo's neck, toucan's beak, heron's leg, pheasant's tail, and the entire hummingbird. As scientists, students will then estimate the size of various animals and then measure them, comparing their estimates to the actual size. They will each have an "inch worm" - a green piece of pipe cleaner one inch long.

Key Criteria
The students will have accurate information on their measurement worksheet.
They will be able to verbally explain their estimate and actual measurement
of specific objects on the worksheet.

Task/Prompt: Inch by Inch

Type: Performance Task

Topics: Measurement, estimation

Student Directions:
You are mathematicians working to estimate & measure the length and height of objects in the room. First estimate the length or height of each object on your Measure It! worksheet. Then measure each object with your “inch worm” and record its height or length. Compare your estimate to the actual measurement..

Rubric:

Stage 3: Plan Learning Experiences and Instruction

Learning Activities:

W
Review measurement through class discussion, learning centers, guided reading, and computer software.

H Use string licorice of different lengths for each student to measure. After the student
has accurately measured his/her piece, they will receive a 12 inch piece to eat.

E
Students and teacher will read a variety of measurement books.
Measurement learning centers.
Computer math software.
Parent volunteers make presentations on how measurement is used in their career.
Measure students at beginning and end of school year and discuss the number of inches grown.

R
Draw pictures of objects in the classroom, measure and record the length of each object in their journals.

E
As scientists, students will estimate the size of various animals and then measure them, comparing their estimates to the actual size.

Teacher observation and evaluation of students' worksheets.
