1. Topic

Comparisons Using Measurement 


2. Content

* practice measuring with stair steps and eventually rulers
Vocabulary:
* measure
* inches 


3. Goals: Aims/Outcomes

1. Use stair steps to measure objects on paper and around room
2. Compare objects to distinguish which is longer or shorter
3. Graduate to measuring with standard ruler 


4. Objectives

1. Measure objects independently after practicing in whole group
2. Complete student workbook page with minimal teacher assistance
3. Work together while measuring objects around the room 


5. Materials and Aids

white board, dry erase markers, teacher book, student book, pencils,
math bags, stair step sets for each child, wooden ruler for each child 


6. Procedures/Methods

A. Introduction
1. Review work from yesterday
2. Reintroduce "Which Is Less?" game
3. The class will be split in half. Two students will come to the
board and each write a number. The class will chant "which is less?
I'll try my best." A volunteer will identify the lowest number for
team points. The game will repeat until everyone has had a turn from
yesterday and today.



B. Development
1. Link comparing numbers in the game to comparing objects
2. Have students help hold up two objects and show how to determine
which is longer and taller
3. Have student volunteers hold up their stair steps and remind class
how we used them the previous day 


C. Practice
1. Students will return to their seats to use their stair steps
2. The class will complete student workbook page 212
3. Class will regroup at end and compare stair steps to rulers 


D. Independent Practice
1. The teacher will give a quick demonstration on how using a ruler
is similar to stair steps
2. The class will go over the items on the measurement hunt sheet
3. Students will work in pairs to measure objects in the room and
record their measurement in inches 


E. Accommodations (Differentiated Instruction)
1. If students are finished with the list before others they may
measure other objects
2. Teacher created pairings will allow solid math students to work
with those who need more practice
3. Assignment includes multiple learning styles 


F. Checking for understanding
1. Hunt sheet will be collected and graded by teacher
2. The class will discuss their answers for a few of the objects



G. Closure
Have the students talk in pairs about what they could use measurement
for in their own lives



7. Evaluation

1. Administer quick quiz where students measure pictures on paper
2. Compare quick quiz answers to the summative assessment at the end
of the unit 


8. Teacher Reflection
