ALEKS

After taking an initial assessment to gauge their competency level, students are presented with a pie chart of competency, a timeline of content to master, and a number of ways to dive into that content. Once they select a subject, they're given a fairly typical textbook-style lesson, with written explanations and vocabulary, worked example problems, and then a series of practice questions.

ALEKS is perfect for math in grades 3-12. The program gives feedback on what students are doing well and struggling with along the way, and it either speeds or slows progression as it measures successful work. As students get through lessons, sectors of their competency pie grow to reflect their emerging skill.
