Every student can succeed

Elayn Martin-Gay's firm belief that each student can succeed shapes all of her texts and video resources. The needs of the student inspire her clear, accessible writing, continued pedagogical innovations, and her popular and effective video instruction. She knows that students don't simply need to be taught math skills; they also need soft skills support that teaches them how to be students. Intermediate Algebra, 8th Edition continues her focus on student success by tightening the connection between her hallmark math instruction and emphasis on study skills, blending them in a new video series.

Hallmark features of this title

  • Concept Checks help students gauge their grasp of an idea as it is presented and help prevent misconceptions.
  • Exercise sets include Guided Applications, Mixed Practice, Concept Extension, and Vocabulary, Readiness & Video Checks.
  • A study skills focus helps students make the most of study time. Resources include Section 1.1 Tips for Success in Mathematics, a Video Notebook to encourage good note-taking, and study skills resources in MyLab Math.
  • End-of-chapter material helps students reinforce concepts in the most teachable moment: when preparing for a test. Getting Ready for the Test exercises help students check their understanding and avoid common errors.

New and updated features of this title
