Algebra 1 Semester 1

Instructional Materials for the WCSD Math Common Finals

The Instructional Materials are for student and teacher use and are aligned

to the Math Common Final blueprint for this course. When used as test

practice, success on the Instructional Materials does not guarantee success

on the district math common final.

Students can use these Instructional Materials to become familiar with the

format and language used on the district common finals. Familiarity with

standards vocabulary and interaction with the types of problems included

in the Instructional Materials can result in less anxiety on the part of the

students.

Teachers can use the Instructional Materials in conjunction with the course

guides to ensure that instruction and content is aligned with what will be

assessed. The Instructional Materials are not representative of the depth

or full range of learning that should occur in the classroom
