Early Mathematics Learning in Family and Community Contexts was the 2019 topic of the Promising Math biennial conference. Framing the event were three plenary presentations that brought cognitive, contextual, and collaborative lenses to the topic.…
Omo Moses, founder of MathTalk, and his colleague, Keith Griffin discuss how they connected over basketball and went on to find local, culturally-relevant ways to engage families in math learning in their own neighborhood.
To encourage and develop children’s counting knowledge, here are eight books (with an accompanying download) that are common to preschool classrooms.
Children look for ways to organize and make sense of their world through play at school and home, as well as at clean-up time. Sorting items into groups by specific attributes gives children the opportunity to define sets according to a rule of what does and does not belong together.
The math story this second grader solves is a change unknown story. There was a full carton of a dozen eggs but some were eaten, leaving only 3 eggs. After making sense of the problem, the child uses a counting up strategy to figure it out.
A second-grade student solves a variety of addition and subtraction math stories. Using his fingers as math tools, he is able to solve the stories, even as what is known or unknown shifts.
A second-grader works on basic number combinations as we see him playing a comparison card game, Capture It. He is accurate when comparing sums but is still developing his efficiency and flexibility, key indications of fluency.
Children love to count. Counting helps them make sense of the world and to find out how many of some. With time and practice, children develop an understanding of the “rules” or principles of counting.
There are all kinds of things to count in pre-k to second grade classrooms. Counting Collections is an activity that develops the Big Ideas of number sense and counting, such as cardinality, one-to-one correspondence, and unitizing.
Books, games, and routines are a natural entry point for math fun in the early years. A new book tells how to tap into children's curiosity to explore the math that is found in everyday life and in play.
