Let's be clear here -- your gripe is, you think you can NOT teach "unsophisticated" 1st graders how to solve missing addend problems?? |

Common Core math standards for second grade: 1) A requirement that students understand place value, for instance, that “100 can be thought of as a bundle of ten tens -- called a ‘hundred.’” 2) That students be able to “add and subtract within 1000, using concrete models or drawings and strategies based on place value … and relate the strategy to a written method.” Also that they “understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.” 3) That they can “explain why addition and subtraction strategies work, using place value and the properties of operations.” 4) And that they can “represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …, and represent whole-number sums and differences within 100 on a number line diagram.” In general, being able to explain how you arrived at an answer – not just memorizing a formula – is also one of the standards’ key goals for students. |
Have you actually read the standards? I have. There really isn't much to criticize there in my opinion. As I said before, my kids are in a common core district. It isn't really that different that the curriculum before (in Maryland but not Montgomery county). I think that the standards should be geared towards what the majority of the kids can do and they will need to find to make it work for those with learning disabilities via exceptions or otherwise. However, I don't think you bore the other seventy five percent of the class No Child Left Behind style. Yes, I've read the standards, and they are rife with problems. Close reading is totally unproven -- Good God, the clueless children that will come out of that curriculum! Most of the math standards are problematic because they insist on explaining in great detail in abstract terms at young ages with writing skills well beyond their ability. Until middle school, kids are concrete thinkers. These standards insist they be abstract thinkers well before the time that they are biologically wired to do so. It's like asking a fish to fly. Many of the issues are in the "fine print" of the appendixes. Those rachet up the reading levels sky high. There are reports of the PARCC test for 3rd graders being at an S, T, U reading level --- even though they should be at about N-O. The other thing is, all bets are off the table for your district's curriculum next year. Here's how this is going to go: Kids will take the PARCC next year. Almost everyone will fail. There will be an uproar. Your school district will panic and buy Pearson's curriculum -- because it's also been well reported that Pearson is inserting its prefab curriculum as the basis for its tests. And on the cycle goes, until parents go to the polls and vote out the politicians who signed up for this boatload of crap. Keep hoping because it isn't going to happen. |

OK, you got me there. Out of 26 2nd grade math standards for 2nd grade, ONE says that students need to be able to explain something. Using place value, So why is 27 + 22 = 49? Because 7 ones and 2 ones are 9 ones, and 2 tens and 2 tens are 4 tens. using properties of operations Why does 10 - 7 = 3? Because 3 and 7 make 10. |
Please answer my question. Are you saying that you believe some 1st graders are simply too slow, unintelligent, unsophisticated, to be able to answer the question 7 + _____ = 10? |
No, I'm sorry, you don't get any choices in our new totalitarian regime. You will take an engineering test in Chinese because that's what the regime has decided you must do. It doesn't matter that you don't want to be an engineer or have ever been taught Chinese. You must know the material anyway. There are no changes and no exceptions or exemptions. You will sit in room for 10 to 20 hours and take an engineering test in Chinese. No excuses. Just work harder, read "closer." You will do this year after year, for at least 6 years. |
FAIL!!!!!!!!!!!!!!!!!! That's not the answer. We need at least three sentences on each problem. |
Actually, each math standard from K on requires extensive explanation. You thing 1 plus 1 is 2? You're wrong. FAIL! |
When you get first graders who do not understand one to one correspondence at the beginning of the year, it is an achievement to have them learn that 7+3=10. That should be the goal. |
Because you fear "frustrating" the poor, underprivileged children? That really bothers me. Personally, I expect that all my students, even the slow ones, will master the grade level math objectives. And so if something is hard for them to learn, I keep looking until I find a way to help them get the concept. And yes, absolutely, there is an easy way to teach missing addends. So you know what DOESN'T work, though? If the only way you teach these poor, underprivileged children to add and subtract is through mastering a simple algorithm, because you believe that's all they can handle. If you only teach children to add by counting on, then they just know that 7 and 3 is 10 because 7... 8 ... 9... 10. If you spend a lot of time, though, helping them learn their number bonds BY HEART, they know that 7 and 3 make ten, and 6 and 4 make ten, and 5 and 5 make ten... WITHOUT COUNTING. And then when it comes time to subtract, they don't need to say 10 and then count down.... or say 8 and count up 2... they just know, because of "properties of operations" that if 8 and 2 make 10, then for the equation: 10 - ____ = 2 ... the missing addend has to be 8. If you spend a lot of time working with these skills at the start, to build up basic numeracy, it is not difficult at all to teach these concepts you seem to think are so complicated. |
When I taught in the projects, I could get them to understand with concrete objects--but transferring that to paper was almost impossible. You have no clue if you have not taught in these circumstances. |
NO. 1 out of 26 grade 2 standards requires "explanation" and that is only in relation to place value and order of operations, which I just showed you in an earlier post is VITAL to being able to solve the missing addend problem you were so concerned about. In first grade, 1 out of 21 standards requires "explanation". And it isn't "Explain why 1 + 1 = 2" It is in reference to adding a 2 digit number to a number that is a multiple of 10. For example, if you add 45 to 20, are you able to explain it is 4 tens being added to 2 tens to get 6 tens. This is not "EXTENSIVE" explanation. |
I don't think you were a very good teacher. |
