Sets are basic to children’s thinking and learning. They are also basic to our number system. One of the most important jobs of each number is to describe “how many” there are in a set of things —be it one, seven, or three hundred and nineteen. Before we can figure out how many apples there are, we have to decide which things are apples, and which are not. Once we’ve created the set of things that are apples, perhaps by separating them from the oranges, then we can count them. Counting requires a set, and as a result, the properties of sets have a large influence on the number system, and on mathematics. © Erikson Institute’s Early Math Collaborative.

On November 18th-21st, 2015 instructors Dr. Hynes-Berry and Dr. Chen attended the annual national conference, presenting on the precursor concepts of math for babies and infants three-years-old and younger.
In this video, a team of preschool teachers looks at video from a classroom to find and discuss evidence of student thinking.
A new book, Thirty Million Words: Building a Child's Brain, explains the importance of regularly talking with children ages 0-3—the time during which the brain develops most rapidly. Ensuring that these conversations take place will help children progress with their language, critical thinking, and interpersonal skills.
A student organizes rocks into different groups based on their unique characteristics.
A kindergarten student organizes a collection of rocks into unique sets. Simple questions can result in explorations in core math concepts such as grouping. In this case, some very unusual groups are created.
