Anyone know the answer to this 2nd grade math problem for me

Nataliesgramma · ‎03-28-2015

I am babysitting and this is one of the problems my granddaughter has:

"Ethan made a 10 to figure out the sum for 9+3. Explain Ethans thinking."

No wonder kids can't do math.....

TIA......

@Nataliesgramma There is something called Illustrative Mathematics, which might be what the math problem is about. That's all I know, but thought it could help you with a Google search? Good Luck

@Nataliesgramma This common core math is the bane of my existence. I've spent hours googling how to do something so I could help my granddaughter. It is totally confusing and I see no purpose in it at all. Wait until 4th grade!! I'm ready to hire a tutor.

I would assume that it means that he "made a 10" by taking one away from the 3 (so, then, 10 + 2) to get the total of 12.

Watch the Make 10 Strategy for Addition on YouTube. My granddaughters went through this nonsense so we taught them the "old" way at home...both excel in math.

Maybe Ethan needs to learn how to add - sorry I can't help

@Nataliesgramma if this is common core, don't expect to understand it. It is ridiculous!!!! Many schools don't even teach times tables!!!! I have no idea who comes up with this stuff.

For you or for her?

@kitcat51 I had no idea how confusing this common core math system was until I tried to help my granddaughter. Sadly, we hung on until 4th grade, but things have taken a turn for the worse this year. I want so badly to show her how easy some of the problems really are without adding the complications, but, she tells me "No Grandma, that's not the way the teacher told us to do it." She is such a bright child, It breaks my heart seeing her fall behind because of this nonesense.
