A clinical-grade learning app that helps children ages 3–7 recognize, sort, and develop foundational understanding of numbers — designed by Dr. Donalee Markus, a Northwestern-trained neuroscientist with 40 years of practice working with children. WHAT IT TEACHES • Number recognition (1–10 and beyond) • Form constancy — recognizing the same number across fonts and styles • Number sorting and basic sequencing • Foundations of mathematical reasoning • Visual processing of numerical symbols WHO IT'S FOR • Children ages 3–7 • Pre-K and kindergarten learners • Children with learning differences who benefit from explicit practice • Children with delayed math readiness • Used by parents, teachers, and clinicians WHAT MAKES IT DIFFERENT Rocket 123s is built on the same three-pillar neurocognitive model that Dr. Markus uses with adult patients — Attention, Intention, Rehearsal. The exercises are hierarchical and progressive, designed to build genuine skill rather than just keep a child engaged. ABOUT THE DEVELOPER Dr. Donalee Markus has practiced cognitive restructuring since 1983, including extensive work with children. She earned her Ph.D. at Northwestern University and completed post-doctoral training under Reuven Feuerstein.
