Built-In Review

At each level, MathFactLab builds in review of fact families from previous levels. The first ten-or-so problems in each activity focus on the facts at the student's current level. After that, there is about a 50-50 mix of current-level and previous-level problems.

In this review mix, facts from recently-completed levels will be reviewed more frequently than problems from earlier. For example, if a student is on Level H (x6), they will see more problems reviewing facts from Levels G (x3) and F (x4) than they will from Levels C (x5) and B (x10).
