Here you can download cards and simple-to-learn game ideas to help young children build their understanding of early math concepts such as cardinality, composing and comparing numbers, and allowing them to subitize.
At the heart of it, graphing in the early years is about quantifying information in order to answer a question. That requires children to organize data in some visible way so that comparisons and generalizations…
Early childhood teacher candidates engage in an adult learning activity that has them order and reorder objects by size according to different attributes.
Examining sets of unit blocks challenges educators to think about relationships of the blocks. A deeper understanding of the features of unit blocks empowers teachers to support children in ways that promote joyful math learning.
Books are a powerful way to launch math investigations with children, but also with adult learners. Our Learning Labs often use picture books as a doorway into mathematics. Here, teachers explore multiple representations of the…
Our Learning Labs open with greetings that serve the dual purpose of building a safe learning community while introducing a math topic in a fun, accessible way. Here, adults directly compare the lengths of paper…
Regardless of how high a preschooler can rote count, a child’s sense of what those numbers actually mean develops gradually. We call this understanding number sense, and it requires relating numbers to real quantities.
