Discussion for Calculating Area of Non-Standard Figures
Linnea Czerney (Teacher (K-12))
This is a great concept! I have done a similar activity with 3rd graders and they loved it. However, it can be very case specific as many classrooms are simply a rectangle and so the challenge would not be as high for any teacher to implement it. By using technology or giving them sample rooms (maybe famous ones, like in the white house or at the mall of america) you could have made an even greater connection to the outside world and potentially used differentiation.
Other than the Youtube video, it seemed to lack a great use of technology. You could have had them show all their work on the computer or work in a program to create a scale model/replica of the classroom to measure the area another way. Then using an online calculator for the math. The youtube video worked perfectly.

I am a fifth grade teacher that is evaluating this lesson plan. Although I have not had the chance to use this lesson in my classroom, I will evaluate the structure of the lesson. The author incorporated a u tube video for student learning on finding the area of triangles and rectangles. This allows students to hear information from someone other than the teacher. This lesson also fostered collaboration. The teacher was conscientious of student behavior, ability, and socialization of peers.
There was no self assessment and reflection to this lesson. This lesson should conclude with a online discussion, classroom discussion, or survey. This would help the instructor see if students truly understand the math concepts. Using clickers could also be a great tool to quickly assess knowledge of all students.
No technological issues found.
