[quote=Anonymous] Common Core math standards for second grade: 1) A requirement that students understand place value, for instance, that “100 can be thought of as a bundle of ten tens -- called a ‘hundred.’” 2) That students be able to “add and subtract within 1000, using concrete models or drawings and strategies based on place value … and relate the strategy to a written method.” Also that they “understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.” [b] 3) That they can “explain why addition and subtraction strategies work, using place value and the properties of operations.”[/b] 4) And that they can “represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …, and represent whole-number sums and differences within 100 on a number line diagram.” In general, being able to explain how you arrived at an answer – not just memorizing a formula – is also one of the standards’ key goals for students.[/quote]
