Take this problem for example:
|Partial-Sums Algorithm || 2 6 8 |
+ 4 8 3
6 0 0
1 4 0
7 5 1
Really - you have to go through all that work to get that answer!?! You can't just teach them to carry the number like we learned. (I thought it worked pretty well that way.)
And this one:
I really don't think this makes ANY sense! Why make them go through all the extra work?
And then there is the issue of money. The way they have been teaching money is like this:
P = penny
D = dime
N = nickle
Q = quarter
But the problem now lies in that my child can't look at coins and tell what they are because they don't have a P,D,N or Q on it and their not all the same size! They rarely use actual money or pictures of actual money.
So when this problem on her most recent math test came home wrong I couldn't get upset with her. They never actually use coins or pictures of coins for anything - except of course on this test!
She looked at it and figured it was the biggest coin so it had to be a quarter. (And to make it worse the coins really aren't even to scale.)
I'm really struggling with the fact that she isn't learning the basics that everyone has always used. Could you imagine an adult standing in line at the bank trying to add up a deposit slip and have to go through all of this to get an answer?
Does anyone elses kids use this format? Does it make sense to anyone else? If your kids use it, do you and your kids understand it?
