Understanding digital supports for early learning is paramount for school readiness and later mathematics learning. We present results from a randomized control trial evaluating a digital app (Measure Up!) and a parent companion app (Super Vision) designed to teach children measurement concepts, a skill that many teachers do not feel comfortable…

Preschoolers' experiences with shapes are important because geometry is foundational to aspects of mathematics and it is now part of the Common Core for school-readiness. Exposure to shapes also provides experiences that are key to developing spatial thinking more broadly. Yet achieving a strong conceptual understanding of geometric categories can…

The project was conducted to make an online tutoring program for math word problem solving accessible to students with visual impairments (VI). An online survey of teachers of students with VI (TVIs) guided the decision to provide the math content in the form of an iPad app, accompanied by print and braille materials. The app includes audio…
