November 21st – 10th Grade Math Exhibitions

Description of Project:
[The students] will provide a poster size graph of simultaneous equations explaining the cost and profit analysis of their wall section (that they will display, built to scale).

Description of project:

Tenth grade math students will exhibit the following:
1. A scale drawing of a frame wall using a scale of 1” = 20” The model is 6” X 24” with a minimum of one scaled 4/0 X 4/0 window
2. A “stick” building (model) of their drawing
3. A poster sized graph (simultaneous equations) representing a construction penalty
4. A poster sized graph (non-linear function) representing cost and profit analysis

Structure: Students will present in pairs which will allow 7 to 10 min. / pair.

Assessment/Evaluation Method:

Stick Frame Wall:
Algebra: Scale: Substitution and evaluation; Simultaneous Equations: Calculating a construction penalty; Quadratic Equations: Cost and profit analysis.

I. The “Stick Frame” Wall Section: Drawing and Model
Using Algebra to find dimensions of model

• Understanding “Scale”: What do the “sticks” represent?
• Understanding structural components of a wall: Why is a header important?
• Based on your scale drawing, how large is the actual building

II. The “Stick Frame” Wall: Cost and Profit Analysis

Using systems of equations to calculate a construction penalty
• How did students graph their equations?
• What is the amount of daily forfeit after deadline?
Using non-linear functions: Cost and Profit Analysis
• How did students graph their equation?
• What is the “maximum” point of you graph and what does it represent?

Attached you will find a rubric that will assist you in evaluating students’ understanding of their projects.

As this experience is incredibly value for a 10th grade ACE student, I thank you for taking time to teach and mentor these future professionals.
