By utilizing mitre, corner, and butt joints, students will develop their understanding of angles and precision in carpentry. Students can challenge themselves further by attempting more complex joints, such as octagonal corners. This project emphasizes the importance of accuracy and attention to detail—skills that are crucial for carpenters.
Joint types used in this project
- Mitre joint: A joint made by cutting two pieces of material at a 45-degree angle, allowing them to join to form a 90-degree corner. Commonly used in window and door trim.
- Corner joint: In this project, the corner joint refers to a vertical cut 45-degree mitre joint that wraps around the corner of the cardboard box. Corner joints are commonly used when wrapping an outside corner using baseboard trim.
- Butt joint: A simple joint where the end of one piece of material is placed against the surface of another piece. In this project, two butt joints are used in the bottom corners of the “door” part of the box. Used when connecting vertical door trim to baseboard trim.
- Octagonal joint: This joint is a variation of the mitre joint, created by cutting four pieces of material at 22.5 degrees. When joined together, these angled pieces form a 90-degree joint with eight sides, resembling an octagon. This type of joint is less common but is still used on uniquely shaped window trim.
Chacun de ces types de joints a une fonction spécifique en menuiserie et nécessite des mesures minutieuses et une coupe précise pour garantir un ajustement correct et une finition professionnelle.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/3″][vc_column_text]L’heure

Étapes
[/vc_column_text][vc_column_text]
- Assemble the cardboard box (10 minutes).
- Glue one side of the box at a time, ensuring 90-degree corners.
- Secure the mitre box to the table using clamps.
- Demonstrate how to cut the first 45-degree angle on the fiberboard.
- Measure and mark the fiberboard (5 minutes).
- Show students how to measure the distance from corner to corner and transfer it onto the fiberboard with a clean mark.
- Cut the second 45-degree angle on the fiberboard.
- Guide students in cutting the second angle in the mitre box, making sure the cuts face the correct direction.
- Check and glue the first piece (10 minutes).
- Instruct students to place the cut piece on the box to verify the length.
- Demonstrate how to secure the piece onto the box with glue, holding it for 15 seconds.
- Repeat steps for remaining pieces (30 to 50 minutes).
- Guide students as they cut and glue the remaining pieces, following the same process.
- Use the different joints on other sides of the box.
- Reflection and clean-up (5 minutes).
- Allocate time for students to reflect on their work and discuss challenges.
- Instruct students to clean up their workspaces and put away materials.

Suggestions d’évaluation
[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text]Practical Skill Assessment
- Observe students during the construction of their cardboard boxes, paying attention to their ability to accurately measure and cut angles, as well as their proficiency in assembling the mitre, corner, and butt joints.
- Assess the cleanliness and tightness of their joints, emphasizing the importance of precision in achieving a professional finish.
[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text]Reflection and self-assessment
Ask students to reflect on their experience and assess their own work. Provide guiding questions such as the following:
- Pensez-vous avoir bien mesuré et coupé les angles ?
- Avez-vous rencontré des difficultés au cours du processus de construction ? Comment les avez-vous surmontés ?
- Dans quelle mesure êtes-vous satisfait de la qualité générale de vos joints et de l’aspect de votre boîte finie ?
- What would you do differently if you were to repeat this project?
