1. Topic-
 Building Bridges with STEM
2. Content-
 angle, centimeter, degrees, converting units, triangle, isosceles, 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?
