You'll be able to see results in few seconds.
Publisher Description
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.
