9、multiplication to develop quick recall of the basic multiplication facts and related division facts.They apply their understanding of models for multiplication(i.e.,equal sized groups,arrays,area models,equal intervals on the number line),place value,and properties of operations(in particular,the di
10、stributive property)as they develop,discuss,and use efficient,accurate,and generalizable methods to multiply multidigit whole numbers.They select appropriate methods and apply them accurately to estimate products or calculate them mentally,depending on the context and numbers involved.They develop f
11、luency with efficient procedures,including the standard algorithm,for multiplying whole numbers,understand why the procedures work(on the basis of place value and properties of operations),and use them to solve problems.G4-FP2Number and Operations:Developing an understanding of decimals,including th
12、e connections between fractions and decimals Students understand decimal notation as an extension of the base-ten system of writing whole numbers that is useful for representing more numbers,including numbers between 0 and 1,between 1 and 2,and so on.Students relate their understanding of fractions
13、to reading and writing decimals that are greater than or less than 1,identifying equivalent decimals,comparing and ordering decimals,and estimating decimal or fractional amounts in problem solving.They connect equivalent fractions and decimals by comparing models to symbols and locating equivalent s
14、ymbols on the number line.G4-FP3Measurement:Developing an understanding of area and determining the areas of two-dimensional shapesStudents recognize area as an attribute of two-dimensional regions.They learn that they can quantify area by finding the total number of same-sized units of area that co
