The unit builds on children’s innate ability to subitize small amounts (1, 2, and 3) and uses it to develop the five-structure, eventually supporting children to see 5 inside of 7, and 5 inside of 8, for example. In the second week of the unit the 10-structure is developed, first as 5+5, and then relationships between equivalent facts are explored and developed using compensation and associativity, for example, 3+7=4+6=5+5.\u003cbr\u003eASIN: 1732043701\u003cbr\u003eVSKU: BVV.1732043701.VG\u003cbr\u003eCondition: Very Good\u003cbr\u003eAuthor\/Artist:Fosnot, Catherine Twomey|Hamm, Janan\u003cbr\u003eBinding: Paperback\u003cbr\u003e\u003cb\u003eNote:\u003c\/b\u003e Any images shown are stock photographs and product may differ from what is shown.  \u003cbr\u003e\u003cb\u003eCondition Notes\u003c\/b\u003e: Book has little sign of wear or use  \u003cbr\u003e","brand":"Blue Vase Books","offers":[{"title":"Default Title","offer_id":43649551761469,"sku":"BVV.1732043701.VG","price":32.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0589\/4225\/9261\/files\/1732043701-0.jpg?v=1789852603","url":"https:\/\/www.bluevasebooks.com\/products\/rhoda-red-and-loretta-leghorn-working-with-fives-and-tens","provider":"Blue Vase Books","version":"1.0","type":"link"}
