\"\"We\u2019ve all seen those pictures making the rounds of children\u2019s common core math homework that makes it look like some sort of crazy, complicated way to do basic math equations. If you\u2019re like me, you grew up before common core. We memorized math equations using tables, because it was the most efficient way to get the answer to a math problem. Memorizing the tables allowed you to immediately know 12×12=144. Unfortunately, you also didn\u2019t<\/em> have to memorize anything that didn\u2019t fit in the table. This is why I can ask you what 34 x 28 is, and say with some measure of confidence that you will either have to scratch it out on paper or use a calculator. Children who have mastered common core math will be able to do that equation in their heads in seconds. Why?<\/p>\n

From the beginning, our children are learning numbers with ten frames, number bonds, and other highly visual methods of number comprehension that break down equations into simple parts. They aren\u2019t just memorizing algorithms, they\u2019re learning how to manipulate numbers in their heads to find answers to math problems. While in these early years, we\u2019re still teaching children basic equations (2+2=4 is called a \u201cstandard algorithm\u201d in common core), we\u2019re also giving them a depth of understanding that wasn\u2019t there before common core math existed.<\/p>\n

You can<\/em> do these equations in your head: 30 x 20<\/strong> = 600; 30 x 8<\/strong> = 240; 20 x 4<\/strong> = 80, 8 x 4<\/strong> = 32. You can<\/em> easily add the four sums in your head, too: 600 + 240 + 80 + 32<\/strong> = 952. But the way you were taught math, you don\u2019t instinctively know how<\/em> to break 34 x 28<\/strong> into those four equations to get the answer mentally: 952. Here\u2019s how they teach it in common core, using what\u2019s called area model math<\/em>:<\/p>\n

Break it down! 28 = 10 + 8 and 34 = 10 + 4. Here\u2019s the area model for the above equations:<\/p>\n

34 x 28 = ?<\/p>\n\n\n\n\n\n
 <\/td>\n20<\/strong><\/td>\n8<\/strong><\/td>\n<\/tr>\n
30<\/strong><\/td>\n600<\/td>\n240<\/td>\n<\/tr>\n
4<\/strong><\/td>\n80<\/td>\n32<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

34 x 28 = (30 + 4) x (20 + 8) = 600 + 240 + 80 + 32 = 952<\/p>\n

It\u2019s a nifty party trick to be able to do big equations using mental math, and it\u2019s also the one of the many goals of our common core math curriculum. Our children are going to be math wizards!<\/p>\n","protected":false},"excerpt":{"rendered":"
