Mathematica + IMLS just answered the question every parent asks: what actually works?

Mathematica and IMLS just identified the five daily practices that build a reader.
Talking with your child — even before they respond in words — grows the oral comprehension and language development Mathematica identified as core engagement constructs for literacy.
Singing nursery rhymes and silly songs builds phonological awareness, the sound-pattern recognition that research shows storytime programs explicitly target in library programming.
Reading together creates the shared reading routines and home literacy environment that Mathematica found predict both frequency and quality of book engagement.
Writing — scribbling, tracing, inventing letters — develops the emergent literacy skills that unfold from birth to age five, long before formal instruction begins.
Playing with other children provides the social interaction dimension that Mathematica's engagement framework links directly to reading motivation and persistence.
These five practices aren't new — they're the research-backed foundation of Every Child Ready to Read, the public library initiative Mathematica's review shows has shaped early literacy programming nationwide for nearly two decades.
