{"product_id":"rhoda-red-and-loretta-leghorn-working-with-fives-and-tens","title":"Rhoda Red and Loretta Leghorn: Working with Fives and Tens","description":"This kindergarten unit in the Contexts for Learning Mathematics series introduces the 5- and 10-bead Mathracks™. 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: LFV.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 is in very good condition.
