Rocket 123s vs Sequence

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.

Sequence is a memory game where you memorize a numbered sequence of tiles, and then tap the correct tiles in the correct order to complete the board. Multiple difficulty levels, grid sizes, and game modes give all players something to challenge them. Unlock infinite mode to see how long you can last! Game modes include: * Sequential numbers (ex: 1, 2, 3, 4, 5) * Non-Sequential numbers (ex: 3, 7, 12, 13, 16) * Multiples of 2 (ex: 2, 4, 6, 8, 10)
