50. The correct answer, of course, is C.

Sep 2014

Look at the illustration. Four shaded squares and three unshaded. There are seven squares. C is the only example that shows the 4 and 3 in an addition equation. 7-3+4. 4+3=7. Students are to compare the illustration with the arithmetic statements. All add up to 7, but only one uses 4+3=7. The equivalent subtraction is 7-3=4. I didn't learn arithmetic this way, but this is not an arithmetic question. It is a question about equivalence, which is something that will be very useful to students later down the mathematics road.

There is method in this that makes sense. The three terms in question are 7, 4 & 3. Equivalence with the illustration means that the only correct answer is C. This is about reasoning, not arithmetic. Reasoning is important, too, in mathematics, and algebra is based on turning equations into other equations.

Good question, and the student got it right.

What you're describing is how I subtract large numbers in my head Recursion Sep 2014 #199

As a first grader, I couldn't because of the too-advanced 'tricks and traps' language. BAD question. ancianita Sep 2014 #111

THIS is a first grade test question ? steve2470 Sep 2014 #114

I've been shocked at what age kids are learning stuff Recursion Sep 2014 #255

Funny, all I see in the news are failing schools, in insane numbers. DebJ Sep 2014 #276

So please show me the good numbers that you refer to. DebJ Sep 2014 #288

I was good at catching on to reading in first grade . . . Brigid Sep 2014 #144

imho the question, even clearly written, is too advanced for a first grader steve2470 Sep 2014 #145

Yep. I remember that too. Brigid Sep 2014 #146

Well gollygee Sep 2014 #181

Or they're just teaching subtraction as addition, which I've seen Recursion Sep 2014 #206

Yeah that's possible gollygee Sep 2014 #220

Obviously what the kids were taught makes a huge difference in whether this is a good question Recursion Sep 2014 #222

She seems to be right, and the question made a mistake by putting subtraction instead of addition Chathamization Sep 2014 #229

Umm... a block 7 units long is divided by color into sub-blocks of 4 and 3 Recursion Sep 2014 #204

I didn't associate the blocks with the question at all. My bad, I guess... n/t TygrBright Sep 2014 #235

They asked for a subtraction problem. There is not one. It's misleading and just plain wrong. madfloridian Sep 2014 #278

The question tests understanding that a problem can be seen more than one way. LeftyMom Sep 2014 #286

I taught these methods for over 30 years. These are first graders, concrete thinkers. madfloridian Sep 2014 #291

You didn't teach that a subtraction problem can be rephrased as addition? LeftyMom Sep 2014 #292

Oh, come on now. Of course that was taught. madfloridian Sep 2014 #301

interesting- it reminded me of using an abacus, which I needed to in order to grasp math. bettyellen Sep 2014 #293

How can you subtract 5 cookies from a cup of liquid? Demit Sep 2014 #320

How did you guess that? I honestly thought they were coins. pnwmom Sep 2014 #343

pnwmom, I was the one who thought they were cookies. Demit Sep 2014 #370

And think about all the ESL kids who thought they at least could do math problems pnwmom Sep 2014 #372

You also have to understand that "cookies and milk" might be culturally loaded... Sancho Sep 2014 #332

Plus, the symbol for a serving of milk would be a glass, not a mug. Demit Sep 2014 #338

Kids deserve the highest quality work in tests like this, since they're being used pnwmom Sep 2014 #346

This test isn't gollygee Sep 2014 #349

Not all standardized tests are graded by computers anymore, especially common core tests. pnwmom Sep 2014 #351

Not the written portions gollygee Sep 2014 #352

And math is treated the same way. Half of it depends on reading skills now, pnwmom Sep 2014 #354

Absolutely. My son got a bunch of questions wrong on a reading test pnwmom Sep 2014 #345

That's funny. I thought they were nickels. pnwmom Sep 2014 #342

I wonder if it's more clear in the original gollygee Sep 2014 #350

No, because a principal at the school that pointed this out pnwmom Sep 2014 #355
