Happy Numbers Now Reports MetaMetrics’ Quantile Measures for Benchmark Assessments

Partnership Announcement: Happy Numbers and MetaMetrics

Expanded partnership between two edtech innovators puts young learners on the path to becoming strong mathematical thinkers

DURHAM, NC & PALO ALTO, CA – January 11, 2023 – The results of the 2022 National Assessment of Educational Progress (NAEP) revealed the distressing impact that the disruption by the COVID-19 pandemic had on U.S. student math achievement. Fourth-grade scores dropped by five points — the largest decline in math since the test was first administered in 1990.

To help reverse this course, Happy Numbers and MetaMetrics today announced an acceleration of their long-term partnership to help ensure that the youngest learners build the rigorous math skills and understanding that will provide a foundation for their entire education and life. Beginning in early 2023, Happy Numbers’ individualized PK-5 online math curriculum will report Quantile® measures for its mid-year progress assessments. For more than five years, students have received Quantile measures from Happy Numbers’ Placement Tests.

“Happy Numbers teaches students to ‘think math.’ They explore the meaning behind math, building upon simple concepts to create connections and develop deep understanding,” said Evgeny Milyutin, co-founder and CEO, Happy Numbers. “By providing students with Quantile scores from mid-year assessments — not just at the end — we can customize the learning pathway to each individual student’s level and progress during the school year.”

Launched nearly two decades ago, the Quantile® Framework for Mathematics uses a common scale and metric to assess a student’s mathematical achievement level and the difficulty of specific skills and concepts. By reporting the Quantile measures for both its placement and benchmark assessments, Happy Numbers provides a powerful tool for personalizing math instruction to help young learners become strong mathematical thinkers. Happy Numbers is designed for small group instruction in the classroom and remote learning at home. Its platform combines technology with the latest educational research to ensure next-grade readiness and a deep understanding of math, helping to close learning gaps and set students up for success.

“A program that supports differentiated instruction is critical for accelerating math learning for young students,” said Malbert Smith, CEO and co-founder, MetaMetrics. “We are proud to extend our partnership with an edtech company, like Happy Numbers, that truly understands that pedagogy supported by innovative technology will help students think mathematically.”

“Incorporating MetaMetrics’ Quantile measures into our mid-year progress assessments will help teachers understand students’ unique strengths and needs, leading to targeted support and success in math. We look forward to the positive impact on student learning and achievement,” said Dr. Mihran Vardanyan, Chief Marketing Officer, Happy Numbers.
