The Dutch do. So  funded by the NSF and Exxon  Mathematics in the City was begun  a collaborative inservice project that pooled the best thinking from both countries. In Young Mathematicians at Work  Catherine Fosnot and Maarten Dolk reveal what they learned after several years of intensive study in numerous urban classrooms. The first in a three-volume set  Young Mathematicians at Work focuses on young children between the ages of four and eight as they construct a deep understanding of number and the operations of addition and subtraction. Rather than offer unrelated activities  Fosnot and Dolk provide a concerted  unified description of development  with a focus on big ideas  progressive strategies  and emerging models. Drawing from the work of the Dutch mathematician Hans Freudenthal  they define mathematics as \"mathematizing\"the activity of structuring  modeling  and interpreting ones \"lived world\" mathematically. And they describe teachers who use rich problematic situations to promote inquiry  problem solving  and construction  and children who raise and pursue their own mathematical ideas. In contrast to other books on math reform  Young Mathematicians at Work provides a new look at the teaching of computation. It moves beyond the current debate about algorithms to argue for deep number sense and the development of a repertoire of strategies based on landmark numbers and operations. Sample minilessons on the use of the open number line model are provided to show you how to support the development of efficient computation.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45647091236917,"sku":"ByrdShop_032500353X","price":31.02,"currency_code":"USD","in_stock":true}],"url":"https:\/\/atxbooks.com\/products\/young-mathematicians-at-work-constructing-number-sense-addition-and-subtraction-9780325003535","provider":"ATX Books","version":"1.0","type":"link"}
