Math Shelf is an award-winning EdTech company that specializes in an evidence-based supplemental math program for Preschool - Kindergarten classrooms. We offer the only experimentally proven early learning tablet math program shown to close the Kindergarten achievement gap. Children who play Math Shelf for just 20 minutes a week in class learn up to 1.5 years more math than comparison students.Research shows that early math skills are critical for a child's long-term success in school and life. However, low-income children start Kindergarten 1 year behind their peers in math, and the gap widens to 2.5 years by fifth grade. Reducing the math achievement gap in and before Kindergarten is the most promising approach to improving children's academic futures.Math Shelf provides over 1,300 sequential, individualized instructional activities rooted in a Montessori approach. The program is accessible to children as young as three, covers math topics halfway through first grade, and is aligned to the Common Core Standards and preschool math learning guidelines and frameworks.Classrooms that use Math Shelf enjoy:• Up to 1.5 years growth versus comparison students in experimental studies• Teacher & parent satisfaction (88% renewal rate)• High levels of math engagement (11,450 activities played per class)• Smiling happy children proclaiming, "I did it!" "I'm impressed with the math children are learning from Math Shelf." -Deborah Stipek, Stanford University Professor
