Number sense is the ability to understand the quantity of a set and the name associated with that quantity. Strong number sense developed in the early years is a key building block of learning arithmetic in the primary grades, as it connects counting to quantities, solidifies and refines the understanding of more and less, and helps children estimate quantities and measurements. © Erikson Institute’s Early Math Collaborative.

Long before young children are writing equations with the equal sign, they are exploring how amounts that look different can actually be equivalent.
Creating grid games from classroom materials can be a great opportunity for fun and mathematical discussions involving small sets.
Grid games can be some of the earliest experiences children have with board games. And they can be both fun and mathematical.
This book is a delightful way to start a discussion about estimation in the early grades. Is it reasonable that Hugh Thomas caught a million fish?
This Spanish-language example of a rekenrek attendance routine demonstrates how one teacher can mathematize an everyday activity.
A quick matching game with dot cards is a fun way for preschoolers to practice recognizing small sets without counting.
Students create visual representations of different numbers. All children will benefit most from exploring number arrangements by beginning with 3 and moving up from that.
Have some Halloween fun with the witch’s tale Room on the Broom. In this lively story by Julia Donaldson and Axel Scheffler, a witch makes room for her animal friends to ride on her broomstick… until there’s one too many animals, and the broom snaps in two. The central question of this book – Is there room on the broom for me? – is a mathematical one.
One of the most classic images of the Halloween season is a witch's magic pot or cauldron. Singing about witches' brew and reading tales of magical pots can also be a great way to introduce math concepts... as long as you find the right book! Below are three of our favorite magic cauldron tales that could be introduced during the Halloween season (or any time) to spark discussion around important math ideas such as doubling, capacity, and measurement.
