## Curriculum Overview

The goal of the Eastchester Union Free School District K-12 math curriculum is to advance student's 21st-century mathematical skills - their abstract reasoning, their collaboration skills, their ability to learn from peers and through technology, and their flexibility as a learner in a dynamic learning environment. Students need to be engaged in dialogue and learning experiences that allow complex topics and ideas to be explored from many angles and perspectives. They also need to learn how to think and solve problems for which there is no one solution—and learn mathematical skills along the way. Adapted from the New York State Next Generation Mathematics Learning Standards

## Elementary K-5: Mathematics

The progression of concepts and skills developed through the elementary grades (K-5) is aligned to the Common Core State Standards.

### Critical Content:

Kindergarten: Counting Skills and Early Addition and Subtraction
Grade 1: Addition and Subtraction within 20
Grade 2: Addition and Subtraction within 1000
Grade 3: Multiplication, Division, and Fractions
Grade 4: Multiplication, Division, and Fractions
Grade 5: Fractions and Decimals

### Required Assessments:

NYS Common Core Mathematics Exams: Grades 3, 4 & 5

### Middle School 6-8: Mathematics

The middle school curriculum connects the learning students have done in the elementary grades to the formal study of algebra, ratios and proportions, geometry, and statistics.

### Critical Content:

Grade 6:  (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) deepening understanding of area, surface area and volume; and (5) developing understanding of simple probabilities and statistical thinking.
Grade 7:  (1) developing understanding of and applying proportional relationships; (2) developing understanding of operations with rational numbers and working with expressions and linear equations; and (3) drawing inferences about populations based on samples.
Grade 8:  (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; (2) grasping the concept of a function and using functions to describe quantitative relationships; (3) analyzing two- and three-dimensional space and figures using distance, angle, similarity, and congruence, and understanding and applying the Pythagorean Theorem.

At the conclusion of 7th grade math, students will have the opportunity to accelerate into Algebra I in the 8th grade.  Placement in Algebra I is based on student achievement in Grade 7 math and readiness.

Algebra I:  Functions; specifically linear, quadratic, and exponential functions
