Grade 4 question: I wanna see if an adult can pass this

[DaSeba5]

This is pretty simple for 4th grade. They made me do algebra in 2nd grade with pawn pieces.

If I was OP I would tell the teacher that the son deserved full credit.

He did the work and how does she know he didn't check it. #2 did say check it and he checked it. Didn't show his work but it didn't ask for that.

You can check it with a calculator or check it with an adult.

[DaSeba5]

50% is ridiculous though. If anything, if the directions asked to check it, and he didn't do it, they should just take a few points off (assuming the teacher explained how to check it to him), but to give him only half credit after getting the answer right is just silly. I mean this isn't high school or college, what does the teacher hope to accomplish?

Thank you for the responses guys.

The correct method and how it was to be checked was to reverse order. Which is 249+379= 628

So my son got the first question right, but question 2 what he did was redo the question and show his work. In fact he did it the long way by showing all the carrying overs. He was not in fact taught reverse order.

This is where I have a problem is because question 2 is so ambiguous a child could have interpreted it several ways. In fact I agree with whoever said "check it with a calculator". All it said was check it with no further instructions. If question 2 actually said "check your answer using reverse order" then the onus would have been on my child

The kid was probably shown how to check it. He should have done that.. How did the other kids in the class go?

To me, the thing to do is ask the other parents. If everyone did it except him, then they taught him what to do, he didn't do it, he should pay more attention. If a bunch of kids were confused, or their parents had to tell them, then it's the teachers fault.

We had a question the other day. Sally has three apples. She also has two oranges. How many vegtables does she have?

So to me it's zero. But it was actually a typo.

Maybe this?

Part of the learning process is kids pass around work and check eachothers answers. Half the kids got it wrong

Don't stress too much about elementary school grades there's no one today successful because they did great in elementary school and there's no one A failure because they did bad in elementary school

Actual grades at this point aren't as important as learning the actual skills and knowledge

Do the kid a favor and teach him the algebraic axioms yourself. Also explain to him that math is so much more than arithmetic so he doesn't get turned off to it like everyone else.

1. 349
2. 628 - 249 = 379

I bet that's also half credit for being a smart ass.

I bet they learnt to do it right the next time though? Success!

[YouGotServed]

probably safe to assume he was taught how to "check it" in class

lol this. Of course they went over it in class.

Your kid's teacher is right. Don't blame the teacher because your kid can't follow instructions.
