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 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 when 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 in Roseville pouring out our hair at the new Mass unbelievably complicated homework assignments these nuts problem circulate did just seem really nonsensical which is really frustrating if you have a kid who has this simple Pro that 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 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 you 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 in this is also for subtraction count up from 38 to 40 then from party 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 that numbers are flexible things made up of other numbers for set 38 minutes to the standard algorithm is the easy and quick way to do it students absolutely still have to learn to do it that way but the idea is that this gives them a better you're 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 but 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 isn't it all and in some cases that's just the parents not understanding it  but in some cases it probably is a bad lesson plan a bad textbook at teacher doesn't quite understand what they're supposed to do differently now they're definitely bumps in the road
