Number DNA™ Skill Builder
What is Number DNA™?
Number DNA™ is an online, self-paced and mastery based software program that identifies then drills down on the missing
prealgebra skills that students need in order to succeed in algebra, trigonometry and beyond. Each unit consist of short (2-5 minute) workouts that provide instant feedback and next steps.
Take a pretest
If needed, work through a series of short practices
Take a posttest
Upon mastery of the post test, move to the next unit and repeat the process.
Programmed into Number DNA are two measures for mastery; accuracy and time.
The accuracy threshold averages 90% over 300+ unique workouts, quizzes and tests.
The time thresholds vary with each topic and are set to prevent using a calculator to solve mental math problems like;
what is 8 x 8? what is 25% of 80?
Or what is -7 -10?
Each unit focuses on mastering selected skills at a high level.
Tedious practice, long chapters, and the lack of timely feedback are motivation killers for many students when learning math.
Number DNA has a radically different design. Number DNA units are short and are comprised of 3-minute workouts that provide instant feedback and next steps.
When students master topics and skills at a high level, they are confident and motivated to take on the next unit of learning.
