# Mathematics

Welcome to the Worcester Public Schools’ Mathematics Curriculum web page. Here you will find information about the Math Curriculum for pre-K through high school and other math resources.

## Pre-K Math

In preschool or pre-kindergarten, students’ activity time will focus on two critical areas:

1. developing an understanding of whole numbers to 10, including concepts of one-to-one correspondence, counting, cardinality (the number of items in a set), and comparison; and
2. recognizing two-dimensional shapes, describing spatial relationships, and sorting and classifying objects by one or more attributes.

Relatively more learning time should be devoted to developing children’s sense of number as quantity than to other mathematics topics.

In kindergarten, students’ learning time will focus on two critical areas:

1. representing, relating, and operating on whole numbers, initially with sets of objects; and
2. describing shapes and space.

More learning time in kindergarten should be devoted to number than to other topics.

In grade 6, students’ learning will focus on five critical areas:

1. connecting ratio and rate to whole number multiplication and division, and using concepts of ratio and rate to solve problems;
2. completing understanding of division of fractions and extending the notion of number to the system of rational numbers, which includes negative numbers;
3. writing, interpreting, and using expressions and equations;
4. developing understanding of statistical thinking; and
5. reasoning about geometric shapes and their measurements.

In grade 7, students’ learning will focus on four critical areas:

1. developing understanding of and applying proportional relationships;

Students will experience an emphasis on readiness for Algebra-I.

In grade 8, students’ learning will focus on three critical areas:

1. formulating and reasoning about expressions and equations, including modeling an association in bivariate data with a linear equation and solving linear equations and systems of linear equations;

## Algebraic Reasoning

This course for 12th graders is intended to accelerate student learning in Algebra where curricular gaps may exist. Upon successful completion of this course, the student will be prepared for entry-level college coursework. Part one of this course covers all basic operations of real numbers, linear and literal equations, graphing lines (using tables, x-and y-intercepts), the arithmetic of polynomial expressions including properties of exponents, solving and graphing linear inequalities, perimeters and areas of basic figures, scientific notation and intrasystem metric conversions. Part two of this course covers major topics in the study of algebra. Students learn to factor polynomials (common factor, grouping, difference of squares and trinomials), perform arithmetic operations on rational expressions and complex fractions, and solve rational, quadratic and literal equations. The course also covers applications including the use of the Pythagorean Theorem, understanding the definition of radical expressions, simplifying radical expressions containing numerical and variable radicands, graphing linear equations using slope-intercept concepts, and solving systems of linear equations.

In this course, students will explore trigonometry and Algebra II topics, including right trigonometric and circular functions, inverses, and graphs; trigonometric identities and equations; solutions of right and oblique triangles; complex numbers; numerical tables; field properties and theorems; set theory; operations with rational and irrational expressions; factoring of rational expressions; in-depth study of linear equations and inequalities; quadratic equations; solving systems of linear and quadratic equations; graphing of constant, linear, and quadratic equations; and properties of higher degree equations.

In Advanced Quantitative Reasoning, students’ learning will focus on three critical areas:

1. critique quantitative data;
2. investigate and apply various mathematical models; and
3. explore and apply concepts of vectors and matrices to model and solve real-world problems.

## Computer Science

In this course, students will solve problems by writing, running, and debugging computer programs; use commonly used algorithms and data structures; and develop and select appropriate algorithms and data structures to solve problems. Students will also code fluently in an object-oriented paradigm using Java. Furthermore, students will read and understand a large program consisting of several classes and interacting objects, showing an ability to read and understand a description of the design and development process leading to such a program.

## Financial Literacy

In this course, students will begin to develop the skills and strategies that promote personal and financial responsibility related to financial planning, savings, investment, and charitable giving in the global economy. Five broad topics will be the foundation of the course: college and career planning, money management, savings and investing, income, and spending. The course will teach students to search and assess college and career opportunities, identify and prioritize their personal money management goals, develop personal spending and savings plans, comprehend the impact of time on the value of money, understand the cost of using credit, and protect assets.

## Topics in Algebra and Geometry

In this course, students will study pre-algebra, algebra, and introductory geometry topics, including the study and applications of formulas, algebraic expressions, linear equations and inequalities; the rectangular coordinate system; area, perimeter, and volume of geometric figures; and properties of triangles and circles.  Particular emphasis will be placed on concepts and skills necessary for success in Algebra II.
