Somehow I have become a walking cliche: a parent who is unable to understand his kid’s math homework. Damn you, ~~New Math~~ Common Core! Damn you to 7734!

So here it is. My kid has to sort “number sentences” (simple equations like 3+4=7) into different groups. Doubles, doubles +1, etc. One of the groups is identified solely as “Mentally Visualized 5-Groups.” I have a notion of what this means but I can’t figure out which “number sentences” would go into this group. Equations with a 5 in them? Equations with 5 as the answer? Help! Any elementary school teachers please chime in.

If I’m reading this and this right, Mentally Visualized 5 groups would be equations with a 5 in them. Perhaps it makes more sense bundled with classroom instruction.

Paging Tom Lehrer… and there are so many rhymes with “common core”…

There is so much wrong with public education these days, and the standardizing of curriculum is just one piece of it. Where are the “get the government off our backs” people when there’s an actual need for them? Answer: they’re behind all this federal testing/common core crap. Agh - don’t get me started.

Yes, it appears Eureka Math defines a “5 group” as an equation with a 5 in it.

I’d be more interested in where this term “5 groups” even shows up in the Common Core - I looked through grades K and 1 and couldn’t find it. The closest I could find is K.OA.A.5, “Fluently add and subtract within 5,” or K.OA.A.3, “Decompose numbers less than or equal to 10 into pairs in more than one way.”

I doubt the term “5 groups” is in the actual Common Core documents.

I see a lot of this term in Google searches from Eureka Math, which is at commoncore.org, but it isn’t clear if they’re just a non-profit making materials based on Common Core or whether they’re actually *affiliated* with Common Core - their URL makes it appear that it’s the latter and yet I suspect it’s the former.

Sorry for the slightly off-topic ramble, but since the OP mentioned – er, damned – the Common Core, I thought I’d post.
