Grade 7 Math
General learning outcome: Students describe the characteristics of 3-D objects and 2-D shapes and analyze the relationships among them.
- Specific learning outcomes: Students perform geometric constructions, including perpendicular line segments, parallel line segments, perpendicular bisectors, and angle bisectors.
Grade 10-3 Math
- Demonstrate an understanding of angles, including acute, right, obtuse, straight and reflex, by drawing, replicating and constructing, bisecting, and solving problems.
Students will learn how to build a small picture frame using a handsaw, mitre box, and hot glue gun. They will understand the importance of precise measurements and proper assembly techniques. Additionally, students will have the opportunity to personalize and decorate their frames.
Carpenters often create custom frames for windows, doors, and artwork. Understanding the process of building a picture frame provides foundational skills for more complex carpentry projects.
50–80 minutes depending on skill level and number of students
- Fiberboard provided (or wood you’ve sourced elsewhere)
- Mitre box
- Hot glue gun
- Decorative materials (paint, markers, stickers, etc.)
- Photographs or artwork to be displayed
- Safety goggles
Plug in glue guns a few minutes before they’re needed.
- Emphasize the importance of safety when working with tools.
- Instruct students to wear safety goggles throughout the project.
- Remind students to exercise caution while using the handsaw and hot glue gun.
Wood cutting and sanding
- Distribute wood boards to each student or group.
- Demonstrate how to use the mitre box and handsaw to make precise angle cuts for the frame corners.
- Encourage students to take their time and double-check their measurements.
- Instruct students to place the wood board in the mitre box and cut the desired angles for each corner.
- After cutting, have students use sandpaper to smooth the cut edges and ensure a proper fit.
- Instruct students to gather the cut wood pieces and arrange them to form the frame.
- Demonstrate how to use a hot glue gun to apply a small amount of glue to the joint and hold it in place.
- Encourage students to work carefully and align the corners as they glue each joint.
- Clamps can be used to hold the joints together while the glue dries.
Decoration and personalization
- Provide various decorative materials such as paint, markers, stickers, etc.
- Encourage students to use their creativity to decorate and personalize their picture frames.
- Remind students to consider the style and colors that will complement the photograph or artwork to be displayed.
Attachment of photograph or artwork
- Instruct students to bring the photograph or artwork they wish to display in their frames.
- Demonstrate how to secure the photograph or artwork to the back of the frame using tape or small clips.
- Encourage students to make sure the picture or artwork is centred and properly secured.
Reflection and showcase
- Have students reflect on their experience building the picture frame.
- Ask them to share their favorite part of the project or any challenges they encountered.
- Provide an opportunity for students to showcase their finished picture frames to the class.
Practical Skill Assessment
- Assess the accuracy of students’ cuts during the construction of their project.
- Evaluate students’ ability to measure and mark materials accurately, as well as their precision in executing the cuts.
- Consider the straightness, cleanliness, and overall quality of their cuts as indicators of their proficiency in using tools and following instructions.
Reflection and self-assessment
Ask students to reflect on their experience and assess their own work. Provide guiding questions such as the following:
- How well do you think you measured and cut the angles?
- Did you encounter any challenges during the construction process? How did you overcome them?
- How satisfied are you with the overall quality of your joints and the appearance of your finished frame?
- What would you do differently if you were to repeat this project?
