Children with stronger math proficiency in elementary school are more likely to graduate from high school and attend college. But most early childhood programs don’t focus on math instruction. What kinds of math programs can improve children’s early math abilities? And can they lead to positive impacts for other longer-term outcomes? The Making Pre-K Count and High 5s demonstrations were designed to rigorously assess whether providing high-quality math instruction, aligned across prekindergarten (pre-K) and kindergarten, could lead to long-term gains across a variety of domains for students growing up in low-income communities in New York City.
