Counting is a part of young children’s everyday life. They love to count everything from the stairs they climb to  More →

Quantity is a particular amount of something, expressed as a number. Quantity cards for young children can have pictures of small sets such as dots, finger patterns, or 5- or 10- frames. The ones we have available on our site use a variety of pictures or “suits,” since matching quantities such as fingers and dots can help develop ideas about equivalence.

What is cardinality? And how is it related to counting? The common definition of cardinality states that it’s the understanding that the last number word said when counting tells how many in all.

Whether teaching in-person with social distancing or online, the number one question we hear from teachers is how to adapt preschool math games for remote learning. Here are some game ideas that work equally well in person or online.

It’s easy to turn reading books with toddlers into conversations about the math that is all around us. The idea of more and less comes into all kinds of books and finger plays toddlers love—including counting books.

Card games provide meaningful practice of the basic number combinations. These common card games that children learn in school or at home can be revisited many times and can be adapted to children’s own math skills as they develop over time.

Activities related to counting books can spark a lot of conversation and creativity. These English and Spanish-language activity cards are great for printing and using at home and school.

In her presentation “Cognition and Early Childhood Numeracy: How Number Concepts are Built and Why Input Matters,” Kelly Mix bridged research and practice in her discussion of math language and learning.

At Promising Math 2019, Kelly Mix gave a talk about how language promotes the development of numerical cognition in young children. Dr. Mix is the Chair of the Human Development and Quantitative Methodologies department at the University of Maryland.

After years of studying 3- and 4-year old children of diverse linguistic and cultural backgrounds, Barbara Sarnecka has zeroed in on the importance of cardinality.
