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

Geometry

• Demonstrate an understanding of angles, including acute, right, obtuse, straight and reflex, by drawing, replicating and constructing, bisecting, and solving problems.

Preparation

Plug in glue guns a few minutes before they’re needed.

Steps

Safety precautions

• 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.

Assembly

• 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.

Assessment suggestions

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?
