# Use │ and • to show the number 52

by Ron
(KY)

My daughter's first grade math homework has a practice problem that looks as follows"

"Use | and . to show the number 52"

I'm lost as to the meaning of the slash and the dot. Normally the dot would be multiplication but shes in first grade and they haven't touched times tables yet. The up down slash I'm lost on. So maybe it's something new since my calculus and finance days :P

Thanks for the help.

 Mar 18, 2012 Thankyou by: Anonymous Thanks so much. I had the same problem this week and was ata total loss.

 Feb 21, 2013 1st grade math ?? Wow by: Anonymous Yes thank you my 1st grade son had the same question and I thought it was crazy n maybe A type error. Lol I'm 43 and I don't recall anything like that way back in my school Days.

 Mar 04, 2013 Thank you by: Anonymous It's pretty awesome that we can type "Use I and dot to show the number 52" into the Google and get this page. After helping my first grader with this question, his theory is that the I or | is a "long" and the dot is a cube, and at some point they learned that ten cubes makes a "long", but I'll be darned if I can remember that from earlier this year. Thank you for tracking down this answer for us!

 Feb 20, 2014 thanks so much by: casey Thanks for posting this I was so confused by the last problem. The things they teach in first grade are pretty crazy compared to what they taught even 10 yrs ago in first.

 Apr 14, 2014 glad I'm not the only one! by: shel My daughter's question was use □ | and ● to show 37 and 283. I'm 40 and have no recollection of this kind of math! I was stumped by 1st grade math!

 Mar 05, 2015 1st grade math by: Lady As I was looking up how to do the fact family, I read the first question about the . And I tried showing my son and he knew the way already. What's confusing me though is #1 9,3,12 ok we did 9+3=12,3+9=12 But this is also on the paper __+__=__, __+__=__ I thought it was only 2addition and 2subtraction unless they want us to switch. And my son claims they didn't learn anything different

 Feb 12, 2016 Thnak you! NEW by: NVS Thank you staff for providing the website link so we could understand the answer and explain it to our 1st grader. My husband and I certainly don't remember ever learning that the "|" represented a stack of 10 cubs.
