Science – Grade 8
Unit of Study: TAKS Review, Preparation, & Testing
CURRICULUM OVERVIEW
Fourth Grading Period – Weeks 1 - 3 (10 - 12 days)
Big Idea
Unit Rationale
Students are expected to meet the standard of 66% (33/50 questions) on the state
administered TAKS test. While most of the TEKS tested are from the 8th grade, 50% of the
test questions are from 6th and/or 7th grade TEKS. A thorough review of the testable TEKS in
the weeks prior to the TAKS will help students meet expectations on this state assessment.
Students need to be provided a timely review of the testable TEKS from the 6 th, 7th,
and 8th grades in order to be prepared for the state administered TAKS test.
