Mathematics Standards of Learning
| NOTE:
These standards were released in early 1997 before either San Diego or California
had established their own mathematics standards. Since that time, both
San Diego
and California have adopted
new mathematics standards.
The standards given below, as well as those for San Diego
and California have been
used as models by other groups around the country that are working on the
development of their own standards.
The Mathematically Correct standards below were designed to provide a rigorous
curriculum that included the needed content for 7th grade students to complete
their background through pre-algebra so that it would support the goal of
algebra-readiness as students begin 8th grade.
The California standards
are also designed to promote algebra-readiness by the end of the 7th grade. In
addition, however, they are intended to be comparable to the standards of the most
academically demanding nations, including Japan and Singapore. With this added
emphasis, the state standards are often more rigorous than the earlier draft
from Mathematically Correct.
The San Diego
standards are intended to be rigorous and world-class standards and consistent with
the objectives of standards development at the state level. As such, they also
target high achievement levels.
Thus, the development of the three different standards has a different history
and differ somewhat in the overall goals that guided development. Any group
involved in setting their own standards is encouraged to study all three
documents.

Introduction
In the Fall of 1996, the San Diego City Board of Education requested
that District staff revise their Draft Content and
Performance Standards to reflect certain key ideas.
Mathematically Correct submitted a draft set of Mathematics Standards for
Kindergarten to Pre-algebra to the Board at their regular meeting
on January 28, 1997. Geometry Standards were presented
to the district Mathematics Standards Committee at their meeting on April 7, 1997.
Algebra I standards were submitted electronically to the Standards Committee
members on April 27, 1997.
These Standards result from examination of multiple sources including the
Japanese Mathematics Standards, the Virginia Standards of Learning in
Mathematics, the Core Knowledge Curriculum, consultation with teachers from
throughout the country, at all levels, and examination of the scope and
sequence of multiple text books and text book series. This document
is a concrete example of our belief that all children can and should learn
mathematics.
These Standards are designed to meet both the request of the San Diego Board
of Education that the district adopt high, clear, grade level-specific
standards, and the guidelines for good standards put forward by the American
Federation of Teachers, including that Standards should focus on academics and
not attitudes, should be grade-level specific, should be specific as to
content, should be specific as to expected performance, and should be
consistent with the Standards of Learning of high achieving countries.
The K-6 standards form part of a logical progression to pre-Algebra, which
would be taught in the Seventh Grade. Mastery of the material in the
Pre-Algebra Standards provides the essential background and skills for success
in Algebra, Geometry and Intermediate Algebra. This goal considers
the achievements of other nations such as Japan and France, and
also with the objectives of the District, as expressed in the Urban Systemic
Initiative, that all students learn mathematics up to or beyond Intermediate
Algebra in high school.
These Standards are based on the students
mastering the material at each level. This mastery at each level is critical
for success at all later levels. It is important to evaluate these standards
with the idea of mastery at each level.
We request that the San Diego Board of Education do three things with this document:
- Use it as a benchmark against which to compare the revised district
standards presented by staff and as a proof of the principle that it is
possible to write high, clear and specific standards for math.
- Request that the district staff review these standards, line by line, and
judge them, for the Board, by the Goldilocks Standard: Too hard, too easy or just
right.
- Direct district staff to incorporate those standards which
are "just right" directly into the district standards, strengthen those
standards which are too weak and incorporate them into the district standards,
and, for those standards which can be shown to be too strong, modify them
appropriately and incorporate them into the district standards.

Pre-Algebra
Students in seventh, eighth or ninth grades who have not taken Algebra are expected to be preparing for Algebra. Various different sources indicate that there are certain essential skills and aspects of mathematical knowledge that a student must master in order to succeed in Algebra. Of particular importance are operations with fractions, decimals and percents, operations with integers and operations using negative as well as positive numbers. Failure to master these makes it extremely unlikely that a student will thrive in Algebra.
These Standards list skills that students should master. They need not be taught in the order presented. Some topics may appear in slightly different forms in different areas. These Standards mention a number of specific skills as well as solving "word" or "real world" problems. Even when not mention explicitly, students should practice and be able to use the component skills in the context of solving "word" or "real world" problems.
Some of these Standards will have been met by students in an appropriate K-6 program. If not, students expecting to take Algebra are expected to meet these Standards in their Pre-Algebra course. For some students, such a course might be designed to take two years. A number of different textbooks should be able to prepare students to meet these Standards, but textbooks that are clearly lacking in large portions of these Standards should not be used for courses that serve as the course before Algebra. Although some textbooks or classroom methods may involve calculators as pedagogical aids, it is expected that a student will demonstrate mastery of the material described in these Standards without the use of a calculator.
