> The traditional method of "borrowing a 1" from the next digit is no longer a valid method of showing work for multi-digit subtraction. The Common Core specifications for any grade are very sparse, and simply lists learning goals for the year. It takes 5-10 minutes to read over an entire grade. > Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. This is the level of specification that the Common Core will offer. Where do you find the story that borrowing is not to receive credit, or is not to be taught? To anyone who has been paying attention, the Common Core advances the CA math curriculum by about 0.5 years, and that's really about it. Students are absolutely learning the same math. Khan Academy is an example of a curriculum which conforms Perfectly to the Common Core. There's nothing racial about it, and it's quite a reasonable curriculum for math in the sum of all things. http://www.corestandards.org/Math/Content/2/NBT/ http://www.corestandards.org/Math/Content/2/NBT/ https://www.khanacademy.org/commoncore/grade-2-NBT https://www.khanacademy.org/commoncore/grade-2-NBT
