Day/Date : 25 Feb - 5 Mar 2025
Unit/Title​
: 4/Shape and Space​
​
Duration
​
: 7 x 30 minutes
Assessment​ : Project: Transformations in Tessellation ​
Title of Assessment
: Transformations in Tessellation
Basic Competence
: Demonstrate knowledge, skills and understanding in
transformation geometry.
Description
: Students create their own tessellation-inspired designs using four
geometric transformations (translation, reflection, rotation, enlargement).
Instructions
●​ You will work in pairs.
●​ Draw a shape on a Cartesian plane and use the four types of
transformations to create a tessellation.
●​ You may research to find inspiration for the pattern.
●​ After completing the design, you will describe the transformations
applied to the shape from beginning to end.

The pattern is unique
and imaginative,
applying all four types
of transformation.
The pattern applies the
four types of
transformation, but
may resemble existing
designs.
The pattern applies
2–3 types of
transformation and
includes common
motifs with minimal
personal touch.
The pattern only
applies 1 type of
transformation and
the design closely
mimics existing
patterns.
Demonstrates
exceptional attention
to detail, paper is
clean, lines are drawn
clearly and the color of
the pattern is vibrant.
Shows good attention
to detail, paper is
mostly clean (errors or
smudges have no
major impact on the
image) and most lines
are drawn clearly .
Limited attention to
detail; several areas
may appear rushed
or unfinished and
shapes may be
confusing or poorly
defined.
Lacks attention to
detail; many areas
appear sloppy or
incomplete and the
design is unclear
and difficult to
interpret;
All transformations are
applied accurately,
resulting in precise
shapes and patterns
that align perfectly with
geometric principles.
Most transformations
are applied accurately;
minor errors in
alignment or shape
may be present.
Some
transformations are
applied correctly, but
several shapes are
misaligned or
inaccurately
represented.
Transformations are
poorly applied;
shapes are
significantly
misaligned or
inaccurately
represented.
Complete explanations
of all transformations
include:
●​ translation : vector
notation
●​ reflection: mirror line
●​ enlargement: scale
factor and
enlargement center
●​ rotation: angle,
direction, rotation
center.
1 or 2 items are
missing from the
explanation.
3 - 4 items are
missing from the
explanation.
More than 4 items
are missing from the
explanation.
Correctly uses
appropriate
mathematical
terminology throughout
the explanation.
Uses some
mathematical
terminology correctly;
minor errors present.
Limited use of
mathematical
terminology; several
errors present.​
Little to no use of
mathematical
terminology;
terminology used is
incorrect.
