so math in some ways it's like baking and math used to be tight as a recipe is a series of steps you do and then you get a result and what you understand if you're a cooker liquor is that you add things in certain proportions for a reason and that you know your cake has to have this percentage of fats to this percentage of flour in order to work what common core tries to do is to do the same thing with Matt sort of developing what they come number sense and number sense is understanding more or less why we do the things we do Common Core is hot in a way that most people over 20 don't recognize that we bought or sold pouring out our hair at the new bunch of shapes and tell the waitress to find my unbelievably complicated homework assignments these nuts problem circulate it just seemed really nonsensical which is really frustrating if you have a kid who has this simple problem it looks like it's being made way too complex for no reason it's totally understandable High people would say  this recipe that I learned is the quick and easy way to do it fire just teaching kids to do that so for example we all learn to borrow when we subtracted but this doesn't really show you what you're doing it doesn't really show you what far away is and so are the ways to Common Core tries to explain this is with a number line because subtraction is really about finding the distance between two numbers start with remember your subtracting and you take little hops up to a moron number so you go 10 between 90 and 100 so you should have broken down this distance and you numbers together  there's another method called the counting up method and this is also for subtraction count up from 38 to 40 then from pretty you want to go up to the next big round number which is a hundred then you need to go from 100 to 300 and then from 303 25 the distance between 38 and 325 are these numbers that I've circled you get this idea in your head the numbers are flexible things made up of other numbers for set 38 minutes to do standard algorithm is the easy and quick way to do it students absolutely still have to learn to do it that way like the idea is that this gives them a better standing and if there are a lot of ways to do this there isn't just one right way to find the solution to a math problem you read through the standards and they seem like really reason good ideas the most important thing is how they're taught teachers understanding what's expected of them having the resources to teach it well because otherwise you do end up with math problems that don't seem to me he sent it all and in some cases that's just the parents not understanding it in some cases it probably is a bad lesson plan of that textbook at teacher doesn't quite understand what they're supposed to do differently now they're definitely bumps in the road
