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.
Cumulative tales and rhymes illustrate growing patterns, typically an increase or decrease by one on each page. As the growing pattern is revealed through the story, children get excited because they can figure out "what comes next."
It’s up to us to find, share, and talk about a variety of shapes with children in ways that expand their understanding and build connections between the shapes drawn on paper and the concrete objects in our world.
Families play a fundamental role in shaping children's interest and skills in math. Schools can help connect the math that exists both in and out of school and nurture families' positive relationship to math.
