,Get the Most Out of
MyLab Math
When it comes to developmental math, we know one size does not fit all. Pearson’s solutions
offer market-leading content written by our author-educators, tightly integrated with the #1
choice in digital learning-MyLab Math. MyLab Math is the teaching and learning platform that
empowers instructors to reach every student. By combining trusted author content with digital
tools and a flexible platform, MyLab Math personalizes the learning experience and improves
results for each student.
• Flexible Platform—
Your course is unique. Whether
you’d like to build your own
assignments, structure
students’ work with a learning
path, or set prerequisites, you
have the flexibility to easily
create your course to fit your
needs.
• Personalized Learning—Each student learns at a different pace. Personalized learn-
ing pinpoints the areas each student needs to practice, giving every student the support they
need—when and where they need it—to be successful. A variety of options are available to
personalize learning in MyLab Math:
❍❍ With Personalized
Homework, students take
a quiz or test and receive
a subsequent homework
assignment that is
personalized based on their
performance. This way,
students can focus on just
the topics they have not yet
mastered.
❍❍ Skill Builder offers adaptive practice that is designed to increase students’ ability to complete
their assignments. By monitoring student performance on their homework, Skill Builder
adapts to each student’s needs and provides just-in-time, in-assignment practice to help them
improve their proficiency of key learning objectives. Available for select MyLab™ courses.
