Principles Underlying Curriculum Revision
•Curriculum Expectations
•Learning
•Teaching
•Assessment/Evaluation
•Learning Tools
•Equity
Areas adapted from N.C.T.M. Principles and Standards
for School Mathematics, 2000
“Icebreaker”
• Select a three digit number. (eg. 346)
• Create a six digit number by
repeating the three digit number you
selected. (eg. 346346)
• Is your number lucky or unlucky?
Do our students see
mathematics as
•meaningful?
•magical?
•both?
“Icebreaker”
• 346346 = 3x100 000 + 4x10 000 +6x1
000 + 3x100 + 4x10 + 6x1
•346346 = 3x100 000 + 3x100
+ 4x10 000 + 4x10
+ 6x1 000 + 6x1
•346346 = 3 x (100 000 + 100)
+ 4 x (10 000 + 10)
+ 6 x (1 000 + 1)
“Icebreaker”
•346346 = 3 x (100 100)
+ 4 x (10 010)
+ 6 x (1 001)
•346346 = (3 x 1 001 x100) + (4 x 1 001 x
10) + (6 x 1 001 x 1)
•346346 = 1 001 x (3x100 + 4x10 + 6x1)
•346346 = 1 001 x 346
AND
1 001 = 13 x 11 x 7
Why is it so
important for
us to improve
our teaching of
mathematics?
Underlying Principles for Revision
• Equity focuses on meeting the diverse learning needs of
students and promotes excellence for all by
– ensuring curriculum expectations are grade and
destination appropriate,
– by providing access to Grade 12 mathematics courses
in a variety of ways.
– supporting a variety of teaching and learning
strategies
Identify 3 key points from your article
segment.
What is one idea from the classroom that
reminds you of these ideas?
Underlying Principle for Revision
• Effective teaching of mathematics requires
that the teacher understand the mathematical
concepts, procedures, and processes that
students need to learn and use a variety of
instructional strategies to support meaningful
learning;

Pedagogical Content Knowledge
• Applying subject knowledge effectively, using
concepts in ways that make sense to students
Teacher:
What is the area of a rectangle with
length 5 units and width 3 units?
Teacher:
What is the perimeter of this
rectangle?
Student:
16
Pedagogical Content Knowledge
• Applying subject knowledge effectively, using
concepts in ways that make sense to student
Teacher:
What is the sin 30° + sin 60° ?
Student:
sin 90°
Teacher:
Is f(x) + f(y) always equal to
f(x+y)?
A Problem Solving Moment
Problem:
What is the sin 50° ?
Answer:
Wrinkles, Grey Hair, Memory Loss
Teaching: Student Engagement
Students develop positive attitudes when they
• make mathematical conjectures;
• make breakthroughs as they solve problems;
• see connections between important ideas.

Conceptual Understanding
• “The concept of function is central to
understanding mathematics, yet students’
understanding of functions appears either to
be too narrowly focused or to include
erroneous assumptions”
(Clement, 2001, p. 747).

Conceptual Understanding
“Conceptual understanding within the area of
functions involves the ability to translate
among the different representations, table,
graph, symbolic, or real-world situation of a
function” (O’Callaghan, 1998).

the world’s population has more than
half the world’s wealth, whereas half
the world’s population has only 1% of
the world’s wealth)…….

Real World Applications
Classroom activities with applications to real
world situations are the lessons students
seem to learn from and appreciate the most.
Poverty increasing: Reports says almost 30 per cent
of Toronto families live in poverty.
• The report defines poverty as a family whose after-tax income
is 50 percent below the median in their community, taking
family size into consideration.
• In Toronto, a two-parent family with two children living on
less than $27 500 is considered poor.
METRO NEWS November 26, 2007
Should mathematics be taught the
same way as line dancing?
A Vision of Teaching Mathematics
• Classrooms become mathematical communities
rather than a collection of individuals
• Logic and mathematical evidence provide
verification rather than the teacher as the sole
authority for right answers
• Mathematical reasoning becomes more
important than memorization of procedures.
NCTM 1989
A Vision of Teaching Mathematics
• Focus on conjecturing, inventing and
problem solving rather than merely finding
correct answers.
• Presenting mathematics by connecting its
ideas and its applications and moving away
from just treating mathematics as a body of
isolated concepts and skills.
NCTM 1989
Traditional Lessons
Direct Instruction: teaching by example.
The “NEW” Three Part Lesson.
•Teaching through exploration and investigation:
•Before: Present a problem/task and ensure
students understand the expectations.
•During: Let students use their own ideas. Listen,
provide hints and assess.
•After: Engage class in productive discourse so
that thinking does not stop when the problem is
solved.
Teaching:
Investigation
Direct
Instruction
“ Effective mathematics teaching
requires understanding what students
know and need to learn and then
challenging and supporting them to
learn it well”
Teaching
The problem is no longer just
teaching better mathematics.
It is teaching mathematics better.

Underlying Principles for Revision
