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.
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…
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.
A child counts an organized collection of bears. Children often sort collections into groups by color. Here, a preschooler assumes he has equal groups until he counts them.
A second grader has a partial understanding of counting in equal groups, but is still working on rational counting. Focus on the Child videos are taken from one-on-one interviews with individual children. The interviews are…
Traditions around food and feasts provide rich opportunities to connect math at school with children’s experiences at home. From Diwali to Thanksgiving, fall is a season of special meals with loved ones.
Along with being "mathical" award winners, these books provide compelling contexts that help primary grade children understand why more advanced counting is useful and that it isn’t always efficient to count by ones.
Moving from one activity to another just got a lot more mathematical with this simple routine that builds early number sense with preschoolers.
Transition time is a great time for mathematizing a daily routine. This dot card transition is a relatively simple routine that builds number sense in a concrete way, allowing them to subitize.
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…
