In 1907 Dr. Maria Montessori opened a preschool in Rome called Casa di Bambini.  It's 115 years later, and today there are over 20,000 Montessori schools worldwide.  Graduates of Montessori preschools have gone on to become leaders in technology, science, business, music, sports, and the arts.  They include: Jeff Bezos, Bill Gates, Larry Paige, Stephen Curry, Joshua Bell, George Clooney, Taylor Swift, Gabriel Garcia Marquez, Peter Drucker, Julia Child and many others. 

Measuring young children's math knowledge is critical for planning instruction, intervening early, and ensuring each student's future school success.  Math Shelf Data Reports measure children's usage, math learning growth, and math achievement.  Data REports are emailed to teachers and administrators weekly throughout the school year.   This blog post describes how to interpret Math Shelf Data Reports and use data consistently to improve children's math achievement.

Math Shelf Usage
In order to learn math, students need consistent opportunities to practice.  Having usage goals helps teachers and administrators keep track that every student is playing Math Shelf consistently. Our recommended usage is that, "70% of students play Math Shelf twice a week for 10 minutes each session."  The chart below in your data reports measures Math Shelf usage. 
     

In 1956, Harvard Professor George Miller published a landmark study called, The Magic Number 7 Plus or Minus 2.   Miller's study found that the average person can remember about seven new things at a time, and that 95% of people can remember between 5 and 9 new things.  This idea is often overlooked when teaching young children their numbers.

Math Shelf is a tablet-based preschool and Kindergarten math program that provides over 1,500 sequenced math games and activities rooted in Montessori instructional approach. The curriculum is accessible to children as young as three, and covers math topics through first grade.

Math Shelf was developed to eliminate early math achievement gaps by providing high-quality math learning opportunities for low-income children.  Research shows that proficiency in early math skills is critical for children's long-term school and life success. However, the majority of low-income children start kindergarten one year behind their peers in math, and this achievement gap widens to 2.5 years by fifth grade.[1]  If educators work to eliminate early math gaps (in pre-K and Kindergarten), we'll reduced time and money spent of later interventions and put many more children on the path to school success. 

Math Shelf's Evidence Base
Two peer-reviewed randomized controlled trials, and one peer-reviewed quasi-experimental study demonstrate that Math Shelf significantly increases student achievement compared to in-class teaching and other leading digital early math programs.

Studies were conducted in organizations serving low-income students, and included primarily Black and Latinx populations. While effect sizes were uniformly large (ranging from 0.57 to 1.53; 6 months to 1.5 years more learning than controls), variation is likely due to study duration and implementation fidelity. Of particular interest is the finding that initially low performing and minority students made the greatest math learning gains. Table 1provides a summary of Math Shelf’s empirical results:

Benefits of early math experiences add up

While literacy is often seen as a cornerstone to scholastic achievement, studies show that mathematical reasoning may be even more crucial as a building block for success in school and beyond. That’s why experts say more attention should be paid to numeracy in early childhood.  Read the full article in Ed Source.

When I work with early education teachers, the first question I ask is, "What math skills should you teach young children first? "  Their answers usually include: counting, numbers, number sense, patterns and shapes.   

While all of these early math skills are important, most children won't be successful in learning them unless they can first understand the concept of similarities and differences.
