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.

Answer:

I know you are writing from Kentucky.

However, this question appears in PDF format on the Home Link 6.5: Fact Routines Practice, page 175 (teacher: Kathryn Kirby’s website, Ka'ala Elementary, Wahiawa, Hawaii)

http://mskirbysclass.com/Documents/Unit%206%20Home%20Links.pdf


The answer is here:

52 = │││││. .



Thanks for writing.

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!

My sister texted me a picture of the question, I thought it was a typo as well. My entire family was completely lost. Thanks so much, who can remember first grade math being like this-- not me. Thanks again

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.

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!

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

Thnak you! NEW

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.
