## 20 Oct Nailing Pattern: How much do you need? CTE Goal:

Have students understand nailing patterns and the requirements. Students will learn the quantities of fasteners needed for different portions of the home building process.

Math Goal:

Students will calculate rates (slopes), equations of lines, and graph the equations. Discussion points include finite and continuous, real life meanings, and domain.

Procedure:

Assign individual students (or groups of students) one of these nailing patterns to research.

1. ¾ inch floor decking
2. 7/16 inch roof decking
3.  7/16 inch OSB wall sheeting
4.  Framing an interior wall (10 ft)
5.  Framing an exterior wall (10 ft)
6.  Nailing shingles for wind prone areas
7.  Screws for ½ inch drywall
8.  Screws for 5/8 inch drywall

Materials needed:

They will need access to building code books or computers/internet and a scale to weigh nails. If you have access to a shingle, a sheet of OSB, a sheet of drywall, it will be helpful for the visual students.

An extension is to look at construction adhesive.

Nailing Pattern

How much do you need?

Your item to research:______________________________________________

Goal:

1. a) You are to find out how many pounds of fasteners are needed per sheet of material. Include a 10% waste factor.
1. b) You are to estimate (predict) the number of pounds of fasteners needed for your item for the whole house. You will need to look at a set of blueprints.

Questions to answer:

1) What is the specifics per sheet of the nailing pattern you were assigned? Include nail size and spacing; remember waste.

2) What is the source of your research? Give website or book and page.

3) Complete the table

 # of sheets 0 1 5 10 # of nails

4) Graph your data

5) Calculate the slope (rate). What is the real life meaning of the slope?

6) What is the y intercept?

7) Write the equation that represents the data you have.

8) Could you use your equation for half a sheet? Explain.

9) How many pieces (sheets) of material do we need for this year’s house?

10) How many fasteners do we need according to your equation?
