Lesson Plan Overview / Details
Summary - This lesson is a hands-on project designed to put into practice what the students have learned in the classroom during the Wood Working Unit. Students will layout, measure and cut wood and then use a variety of fasteners to assemble a wood sawhorse.
Students will practice layout and measurement techniques, demonstrate power tool safety and use, construct compound angles, and follow correct assembly processes. This project will also require students to work together during the assembly process and/or to develop assemble aids (jigs, etc.).
Some suggestions for project modification will be made as well.

Objectives and Goals
By successfully completing this project students will be able to: 1) Read a plan to obtain critical dimensions, 2) Measure and layout a wood project, 3) Identify by name common woodworking tools and materials, 4) Select and properly use hand and power tools used in woodworking, and 5) Cut and assemble wood components successfully.
Activities in this Lesson
- Project Introduction - Hooks / Set
At the start of class have two things in the front of the room:
1. A store bought wood sawhorse (Home Depot sells one that is the basis of this project).
2. A sample finished project that you (the teacher) constructed.
Start the discussion by explaining that when you were at Home Depot you came across this sawhorse and thought that this would make a nice project for the students to complete for three reasons:
1. Constructing a sawhorse would be a practical way to demonstrate the skills learned during the wood working unit.
2. This is a project that would be useful at home and could be displayed at the county fair(s).
3. Constructing this project will be the hands-on "test" that the students will take for the wood working unit.
- Project Overview and Demonstrations - Demo / Modeling
In this section you will review the instructions and project materials with the students using the "Wood Sawhorse Instructions" power point slides. Also, use the "Student Packet" to help the students to follow along and to take notes from the power point. There is a student worksheet included in the student packet that will bring out important details in the construction process.
- Sawhorse Tools & Materials ID - Assessment
This is a power point file of tools and materials used to construct the Sawhorse. Also included (in Word) are a Tool & Materials ID Quiz and the corresponding answer key.
- Wood Sawhorse Construction - Lab / Shop
Over the next few days the students will work in the shop constructing their sawhorse. Supply a set of plans to each student. The plans contain pertinent information such as instructions, materials needed, and tools used to complete the project.
Also, give some thought to how you will channel your students through the shop to see where the "bottlenecks" will be (parts of the construction phase where students have to wait long periods of time to use a tool). This will depend on the availability of tools, work bench space, and traffic patterns. A recommendation would be to set up stations so you can spread the students out and utilize your tools and space more effectively.
- Shop Management - Closure
This activity will take place at the end of each Lab/Shop session. It is important to have prepared some sort of an organized clean-up routine.
Things to consider are:
1. Accounting for and putting away tools.
2. Storage of materials and supplies till the next Lab/Shop session.
3. Storage of partially finished or finished projects.
4. Clean-up of the shop (ie. sweeping).
Recommendation: Since this project will take 5 to 7 Lab/Shop sessions, split the class into 4 groups and assign each group to complete one of the items on the list above and rotate the groups each day.
- Modifications to this project - Other
Successful completion of this project may depend on the availability of tools and/or resources to pay for materials. Also, construct a sawhorse yourself before taking this on as a class project to see where the pitfalls (difficult parts of the project for the students) and "bottlenecks" will be. Consider the following:
1. Safety - Review safety rules for hand and power tools as needed. A compound miter saw is actually safer and easier to use than a circular saw.
2. Tools - If a compound miter saw is not available, a power circular saw would work instead. A hand saw would make this project very difficult to complete.
3. Assistance - Be prepared to assist the students with the more complicated portions of the project, especially when marking and cutting the compound angles.
4. Materials - To reduce costs, shorten the length of the legs and the top of the sawhorse. A 24" top and 24" legs will sufice. Shop around for materials and consider alternative wood sources.
- Assessment Types:
- Rubrics, Projects, Observations, Student Worksheet
Rubrics and worksheets are in the student packet. Also, it is a good idea to evaluate each students project as they are finished to give immediate feedback. Or, provide feedback in stages by grading each criteria as they are completed.
