Seriously, there's an app for multiplication tables. I had to do nothing except be strict enough to make the boy practice a few minutes a day. The bar is set pretty darn low...

Same here, though I seldom found an occasion to use Pall Mall and Cutty Sark in a sentence in Kindergarten.

Please do.
Thanks in advance.

Spectrum Math is not a CA State adopted curriculum. You can buy these books at Walmart. Below is the list of curriculum approved by CA.

Exactly.

Similar to the way I learned it after years of being frustrated with carrying, borrowing, moving numbers here and there, etc. Except in my head I do 37x17 a little different than you did. I go ahead and round the 17 up and multiply 37x20 equals 740, then I figure the 90 (30x3) and 21 (7x3), add them together to get 111 and take that from the 740 to get 629. Same result, different pathway. You also mentioned percentages. Dad drilled into me (and I am glad he did - he would watch me trying to carry numbers by counting on my fingers and his blood would boil) that I can always come close to 10% or 1% by moving the decimal to find .1 or .01, I can then use my mental multiplication to find figures very close to actual percentages quickly. When we watch "The Biggest Loser" my wife and I like to see how close I can get to their actual percentage before it pops up onto the screen. Just a nerdy skill I picked up! I also figured out in high school to add and subtract by beginning at the left instead of the right and forget all of the "borrowing" and my life got MUCHO EASIER!

I sometimes do it the same way you did, depends on the moment.

Whoa! No way I could switch back and forth. I gotta stick with what has worked. And I can't do those in 2 seconds like you. More like 10! Ha

I've got a little 'Rain Man' in me when it comes to math.

Of course I have the artistic abilities of a rock.

Kick that around with a little 420. It be clear then!!

You nailed it...

Ok - get yourself a copy at your nearby Walmart then. I think my wife picked these up at a local bookstore, as there is no Walmart within 30 or so miles. At any rate, regarding renaming and the CA curriculum:

From reference.com



And from http://www.cde.ca.gov/be/st/ss/documents/ccssmathstandardaug2013.PDF




So, renaming does appear to be part of the CA curriculum. Though in the CA text it is referred to as "compose" and "decompose". But I could be wrong. Is there a difference between "renaming" 339 as 33 tens and 9 ones, vs saying 339 decomposes to 33 tens and 9 ones? Would it be less or more decomposition to say that 339 is 3 hundreds, 3 tens and 9 ones?

Racist, homophobe.

Not trying to veer the thread off course but perhaps you can verify something someone told me about the way the Chinese say numbers which automatically helps their children with math.

Instead of pronouncing the number 37 as thirty seven (or as the Germans call it seven and thirty), the Chinese would call that three tens seven, is that correct?

What I mean, is that people NEED repetition and practice in order to retain what they've learned. One of the best ways to do that in a formal school setting is through homework. To not do so at ages 6-9 leads to 17 year old clerks that can't make change without punching it into the register. Or they go all "deer-in-headlights" when you give them a $20, and 10 seconds later after it's been entered, you give them another 17 cents on your $16.67 bill...

Which is somewhat the premise of the movie Idiocracy, that the world in 500 years will be solely populated by what are now considered idiots. Those people with a high IQ having been displaced from the gene pool by the fecundity of the stupid. [/quote]


There seem to be a lot of studies out from some Scandinavian countries that have suspended homework that are testing way better than our kids.

If you receive crap instruction while you are in class, it does not seem to matter how much homework you get.

I would much rather a kid gets his work done in school and then comes home and gets to be a kid after getting his chores done.

What good does the ability to make instant change in your head do when you are living in your parents basement?

Renaming means changing the name...
Decomposing means breaking down.
Understanding that 343 is 3 hundreds 4 tens and 3 ones is very important. Place value is huge for kids.

The discipline I mentioned earlier would go a long way to making this feasible.

I don't know what sort of time kids are given to work problems in class these days - I do remember having very little primary school and middle school homework myself, as I was very motivated to get it done in class so I didn't have to take it home...

Granted my daughter is only in the second grade, so I am sure things will change over time, but she ALWAYS finishes her assignments in class.

Its the 5 to 15 pages of work that is handed to them as they walk out the door that bothers me.

Its a stressful deal when she comes home with all that work. I get riled up when 2+6=applesauce.

I would imagine that if she has kids it will be easier.

My genius buddy actually likes some aspects of common core.

Since he is the reason I passed geometry and is a nuclear engineer, I guess I have to take his word for it.


Until public education is worth a dang, I will advocate the kids get outta there ASAP.

You can always pay for private school...

Yup, paying twice shouldn't bother you. It's for the greater good.
