But what does mathematical understanding look like? One hallmark of mathematical understanding is the ability to justify, in a way appropriate to the studentâ€™s mathematical maturity, why a particular mathematical statement is true or where a mathematical rule comes from. There is a world of difference between a student who can summon a mnemonic device to expand a product such as (a + b)(x + y) and a student who can explain where the mnemonic comes from. The student who can explain the rule understands the mathematics, and may have a better chance to succeed at a less familiar task such as expanding (a + b + c)(x + y). Tim, Where are you quoting from? I don't see that quote in a previous message. Is it from the Common Core, or......... Please give us a reference point to your quotes. Otherwise the quotes don't make any sense. Thanks, Bill
