“More” is often one of children’s first words. Infants attend to difference though they don’t yet discriminate between “more” as quantity or magnitude/size or intensity of sensation. Toddlers are beginning to differentiate between attributes and…
It turns out that mathematical thinking is developed in conversation with others; asking students “how do you know that?” will reveal a child’s mathematical reasoning skills. The ability to explain one’s thinking is a cognitive…
This child uses the visual arrangement of a ten frame to conceptually subitize quantities into the teen numbers. He recognizes a full row as a unit of 5 and uses that to derive larger numbers…
This child encounters a new type of problem situation: a part-part-whole story where both parts are unknown. He is uncertain how to model the problem at first but has some success with adult support. Focus…
This child uses cubes to model a part-part-whole problem where the whole is unknown. He uses a counting all strategy. He counts out each part and then counts them altogether, starting from one. Focus on…
We all know that babies aren’t born walking, talking, following directions, counting, or measuring size. But they do enter the world hard-wired with instincts that will mature and develop into those skills in the preschool…
We are excited to launch RJEM in 12, a series of short and insightful interviews with researchers, teachers, community members, and other stakeholders whose work advances racial justice in early mathematics. Our first guest is…
This series from the Racial Justice in Early Math project highlights researchers, program facilitators, educators, and others who are actively working to advance the discussion around racial justice and the field of early mathematics. To…
Although I never met him personally, Bob Moses has shaped my life for the past two decades. Reading his book Radical Equations inspired me to focus my doctoral dissertation on math teaching and learning and…
Released in 2021 by Teachers College Press, this book extends professional knowledge for mathematics teaching to teachers who work with the very youngest learners.
