2nd grade math question

[texaspacker]

This one!

13. He didn't serve any fractions of slices he served 13 slices.

Xrod beat me to it.

He cut 16 equal pieces but only served 13 of them. So he had 3 equal pieces left over.
I did not read anyone's answers until after I came up with my answer but I used your daughters test question only.
It looks like Xrod & Sideler beat me to it!

The way the way you worded your question & how it was worded on your daughter test are different. Uhhhhhhhhhhh whut did I just say? My brain hurts!

[texaspacker]

That figures

My daughter is in 7th grade. My son is in 5th grade. Over the elementary school careers, I've many of their worksheets that were very poorly written—poorly written to the point that you couldn't discern what was being asked or there were multiple correct answers.

Here I would have said 13/16 but see how someone else could get 1 5/8.

This way they can choose both the right or the wrong and still pass. Thank you SAT!

This is the problem with the education system. Don’t even use real world situations to help kids learn. It’s sad. Very sad

The answer is obviously “Canadian bacon with pineapple”, fellas....

In all seriousness, common core is turning our youth in to mindless, spineless, good little socialist. I totally get why my sister took her four kids out of public school and is home schooling them.

If it asked "How much of the Pizza was served"? Answer = 13/16
If it asked "How many Pizzas were served"? Answer = 1 5/8
Question was "How many slices"? Answer = 13
She answered correctly with a logical assumption relative to total amount.
The question is poorly written, especially for the 2nd grade.
Some other teacher, years down the road will mark off for not answering a question exactly as it is written. As others have said before, grammar and punctuation play a big part... Well, except on internet forums, where it is perfectly acceptable.
FWIW - Thin Crust, Hamburger, Mushrooms, & Bell Peppers.

I use everything from addition all the way up to trig every day. My granddaughters 4th grade math makes my head hurt. I've got her teachers number on speed dial. The way they teach really makes my blood boil.

13/16 slices or 81.25%

13/8= 1 5/8 Pizzas


If they second part of the question is pertaining to the correct answer in Question 9

[boomerball]

Everyone is wrong, including the book/teacher. It asks for the number of slices served in a fraction format. Should not matter how many total slices to begin with, only how many were served, which was thirteen. Answer should be 13/1.

correct.
"number of slices served" = 13 = 13/1 (as a fraction)
"fraction of total available slices served" = 13/16
"number of pizzas served" = 13/8

I bet a cool 20$ bill the teacher can't read a 12" scale. HAHAHA sorry

So if I am understanding this correctly, an answer key is in the back of the book. So the correct answer is look in the back of the book

I agree with 95/100ths, um I mean 19/20ths of this post. Pepperoni with mushrooms and black olives

I bet she could if it was from Harbor Freight with the dummy marks on it.

[Bassdeer]

Can I have the last 3 slices?

[Dusty Britches]

As I'm going over my daughters math review for her test tomorrow, I come across this question. She writes down 13/8. I explain there were 16 total slices and 13 were served so it would be 13/16.

Then I look at the answer key and sure enough it says 13/8 or 1 5/8 are the correct answers.

So no, I'm not smarter than a 2nd grader.

This is why our kids can't pass the SAT or ACT.

The question states there are 2 pizzas cut into 8 equal parts EACH. 2x8 = 16. That is the whole of it. 13 slices served. 13 of 16 served. 13/ 16.

Now, if you wanted to know how much pizza was served - 1 whole pizza and 5/8 of the second pizza.

[Oz_Ag]

Was 13/16 of a slice served? No
Was 1 5/8 slices served? No

13/16 of all the pizza there was served.
1 5/8 total pizzas were served.
13/1 slices were served. (Only correct answer in this case)

It's all in the way you word the question.

Shoot, that’s why high school graduates can’t even pass an ASVAB test.
