Topic
Geometry Formulas Discovery Question- How can knowing the perimeter or area of an object be useful outside of school?

Grade Level
7th

Time Frame
45 min.

Instructional Objectives
Students will be able to the areas and perimeters of basic geometric figures on paper and in a real life setting,

Materials
Measuring tapes (enough for one between three) Rulers (one per student) Calculators (student provided) Paper and pencil (student provided)

Procedures
Focus Attention/Motivation: Teacher will first show an overhead projection of several basic geometric figures and the formulas for their perimeter and area

Instructional Input & Modeling: Teacher will then take suggestions from class as to how to apply these computations beyond pencil and paper. Teacher will pick an object in the classroom to measure for perimeter and area as a demonstration.

Student Engagement/Practice: Students will divide into groups of two or three and will be asked to measure at least 5 objects in the room (teacher will have placed several geometric objects in the room ahead of time). Students must find both the parameter and the area of the object.

Closure: Homework- students must research and bring to class five to ten examples of how area and perimeter are necessary beyond the classroom.

Rubric Assessment
more than 5 objects || Students measured 5 objects || Students measured less than 5 objects || perimeter of all objects successfully || Students calculated perimeter of most objects successfully || Students attempted calculations but were incorrect or incomplete || area of all objects successfully || Students calculated area of most objects successfully || Students attempted calculations but were incorrect or incomplete || for full amount of allotted time || Students were on task for most of the allotted time || Students were frequently off task during the allotted time || real world references. || Students provided 5-7 real world references || Students provided less than 5 real world references ||

Accommodations
Students with computational problems will be provided with an outlined note sheet which includes the formulas necessary for the class work. Students may only be required to bring in 3 real world references as part of the homework.
