General Outcome: Describe and analyze position and motion of objects and shapes.
Authorized Resource
Performance
• ‘Reflective Reflections’- Ask students to place three geoboards in 
a row (see figure below). On the middle geoboard, they could 
construct and label a quadrilateral. Using the edges of the middle 
geoboard as lines of reflection, construct the reflected images on 
the other two geoboards. Ask students to record the figure and the 
two images on geopaper provided and label all three figures. Ask: 
What are the similarities between the first shape you created and its 
reflected images? How are they different? Compare the reflections. 
What do you notice?
(5SS7.3)
• Ask students to reflect ABC using the given line of reflection. Ask 
them to describe the position and orientation of the reflected image 
and justify why their drawing is correct. 
(5SS7.4)
Paper and Pencil
• Triangle Reflection: Ask students to work in pairs to: 
(i) Draw a triangle 
(ii) Label the triangle ABC
(iii) Draw a line of reflection
(iv) Reflect the shape
(v) Connect the corresponding vertices
(vi) Label the image
(vi) Describe the distance of the image from the line of reflection
(vii) Describe the orientation
