Adaptive fluency: Number Gym

Every grade 1-5 Independent Digital Lesson includes Number Gym, an adaptive fluency activity that helps students build foundational number sense. For older students, Number Gym activities are designed to bridge K–5 math foundations, reinforce previously learned skills, and address areas of unfinished learning.

As students demonstrate proficiency in an activity, they progress to larger numbers and more challenging portions of the Number Gym sequence.
