scalene, equilateral, side 


3. Goals: Aims/Outcomes

1. Introduction to measuring straight lengths and angles
2. Teach students to convert units
3. Teach students about different triangles 


4. Objectives

1. Students can now measure using a protractor and find unknown
angle measurements in triangles
2. Students can now measure with a ruler and can convert units
3. Students understand the differences between the 3 types of triangles 


5. Materials and Aids

wood glue, binder clips, graph paper, popsicle sticks, pencil, ruler,
protractor, newspaper 


6. Procedures/Methods

A. Introduction
1. Explain how to measure using a ruler and protractor
2. Explain differences between 3 types of triangles
3. Explain how to convert units 


B. Development
1. Showing different types of bridges
2. Showing blue prints
3. Explain how to find unknown side lengths for right triangles 


C. Practice
1. Practice creating blue prints
2. Practice measuring angles and straight lengths
3. Practice converting units 


D. Independent Practice
1. Create blue prints in a group
2. Convert popsicle stick measurements to blue print (graph paper)
measurements
3. Build bridge with popsicle sticks 


E. Accommodations (Differentiated Instruction)
1. Work in groups
2. Create bridges online
3. Research types of bridges online or in books 


F. Checking for understanding
1. Quiz on measuring angles and straight lengths
2. Quiz on converting units
3. Quiz on types of triangles and finding unknown side lengths in
right triangles 


G. Closure
1. Create a huge bridge as a class
2. See how much weight all of the group bridges and class bridge can
hold 


7. Evaluation

1. Did the students learn how to measure using a ruler and protractor?
2. Do the students know the differences between the 3 types of triangles,
and how to find unknown side lengths in right triangles? 


8. Teacher Reflection

Was the lesson successful? Were students interested/bored?
