“The principles are statements reflecting
basic precepts that are fundamental to a
high-quality mathematics education.”
-NCTM Principles and Standards

Content and Character
Decisions made by teachers, school
administrators, and other education
professionals about the content and
character of school mathematics have
important consequences both for students
and for society.
-NCTM Principles and Standards

Content and Character
The Standards describe the mathematical
content and processes that students
should learn.
Content and Processes
The Principles describe particular features
of high-quality mathematics education.

Learning
Students must learn mathematics with
understanding, actively building new
knowledge from experience and prior
knowledge.
Understanding

Equity
Excellence in mathematics education
requires equity—high expectations
and strong support for all students.

What Does “All Students” Mean?
It does NOT mean that all students are the
same. Students have different abilities,
needs, and interests. Yet all students
deserve an opportunity to understand the
power and beauty of mathematics, and they
need to be able to use mathematics in their
personal lives, in the workplace, and in
further study.

TX ACC. promotes the Equity Principle
•At-risk students could no longer be
ignored
•No ethnic group could be ignored
11
Teaching
Effective mathematics teaching requires
understanding what students know and need to
learn and then challenging and supporting them to
learn it well.
-NCTM Principles and Standards
12
Technology
is essential in teaching and learning mathematics;
it influences the mathematics that is taught and
enhances students' learning.

Technology vs. Teaching
Would you choose the world’s greatest
technology or the world’s greatest teacher
for a child you love?

What we really want…

Curriculum
A curriculum is more than a collection of
activities: it must be
•coherent,
•focused on important mathematics,
and
•well articulated across the grades.
-NCTM Principles and Standards
23
Assessment
should support the learning of
important mathematics and furnish
useful information to both teachers
and students.

Assessment
• TAKS –Higher Expectations – a good thing.
• It will be tough on all of us to rise to the
challenge.
• But we SHOULD and we CAN…

Learning is our motive
for all that we do.
Everything we do is designed to
support that.
