# Map of MCAS Objectives to Fisher Web Site, Grades 7–8

Grades 5–6 MCAS Objectives
Grades 9–10 MCAS Objectives
Mathematics Curriculum Framework (Massachusetts Department of Elementary & Secondary Education)

MCAS stands for Massachusetts Comprehensive Assessment System.

As required by the Massachusetts Education Reform Act of 1993,
students must pass the grade 10 MCAS tests in English Language Arts and Mathematics
as one condition of eligibility for a high school diploma (in addition to fulfilling local requirements).

In addition, the MCAS program is used to hold Massachusetts schools and districts accountable, on a yearly basis,
for the progress they have made toward the objective of the No Child Left Behind Act
that all students be proficient in Reading and Mathematics by 2014.

MCAS tests measure how well students have learned the academic standards outlined in the Massachusetts Curriculum Frameworks.
All Massachusetts public school students take MCAS tests: each year in grades 3 through 8, and at least once in high school (usually grade 10).

This page lists the Learning Standards that form the basis for MCAS, and then provides links to my web exercises covering the material.
Of course, concepts are often covered in many different exercises; I have tried to provide the most relevant links.

Five strands organize the MCAS mathematics content:

• Number Sense and Operations
• Patterns, Relations, and Algebra
• Geometry
• Measurement
• Data Analysis, Statistics, and Probability

Each learning standard has a unique identifier (like 8.N.2) that consists of:

• the grade level (8.N.2)
• the strand (8.N.2)
• the standard number (8.N.2)

For example,   8.N.2   is a 8th grade standard in the ‘Number Sense and Operations’ strand, and it is the 2nd standard in this strand.

The learning standards specify what students should know at the end of each grade span.
Students are held responsible for learning standards listed at earlier grade spans as well as their current grade span.

The LINKS TO FISHER SITE (right column, below) often provide a higher level of understanding than that required for the MCAS grades 7-8 test.
However, these exercises can be used as a reference by teachers.
Also, these links illustrate that grade 7-8 MCAS objectives are being reviewed and developed in the high school curriculum,
thus preparing students for the MCAS test in grade 10.
