Lynn,
I am just beginning to use DM with my 7yods. Let me give you some background.We were using Right Start and after
spinning our wheels until the end of April, he still didn't know his numbers, nor could he identify quantities above 3.
Obviously, he is on the severe side of things.

A wonderul woman recommended "Mathematics Their Way." After just
2 months, he has greatly improved in recognizing 0-9, count them (somewhat) confidently, and write them. This seems
like an absolute
miracle to us. The activities are arranged
developmentally . This has been key for him. RS
assumed one-to-one correspondence and that the child was ready to identify groups of quantities...not my son. No crime
on their part, most children know these things or pick them up quickly. I figured that with a little work he would be up to
speed in no time, after all, he is very bright. It didn't happen.

I spent the middle part of our school year learning
about dyscalculia (no number sense), and how to remediate it. He has been doing beautifully with MTW, every developmental
step hs been provided for. However, it only goes through 2nd grade. We have some time yet before we outgrow it,but I have
started looking into where we may be headed. I have known about DM for almost 20 years, but have never needed it. I
have taken a fresh look at it recently and can't believe how differently I see it now. Similar developmental progressions
are used in DM that I am using in MTW. I never understood why DM did lessons the way the did, now I do. That's why I am
so quick to endorse it. I feel like I have been using it for the last 2 months...the
system, that is. Every concept that is
covered in DM somewhat follows these progressions: Pictoral (or semi-concrete) stage -Connecting stage-Abstract stage.
Actually, I think they have broken down the above into four separate stages. But you get what I mean...no assuming is done.
My order should be arriving in a couple of days. My son will be thrilled, he loves workbooks but still needs a developmental format. I have discovered that hard to find
anywhere, much less a workbook. We will stay with MTW until he outgrows it, and use the DM workbooks as supplements and treats in the meantime. My hope is to transition to DM full time after MTW. I am not saying that he will always use DM, who can say what they will be doing so many years down the road? I do know that the system works for him
now. Because we have not had him tested I can't claim that he
is a dyscalculic, but all the markers are there. I would love to wake up one morning and my son not have these issues anymore. But if that never happens, I am prepared to deal with it. So, give DM a try over the summer? See if it makes a difference for him. I don't know where he placed in the test, but CBD has some imperfect copies that they are selling at a discount ($6.37). The Instructor's guides are basically useless, just answer keys really. BTW, DM doesn't get into all the side-shows in math. They stick to straight-up math concepts: addition, subtraction, multiplication...etc. Also, it is not written to be teacher-taught. The design speaks directly to the child (unless the child is a non-reader). The teaching is in the actual progression of lessons, they are quite logical and well thought out. If it did work for him, how would
you deal with the differences from other programs? He probably wouldn't be "on level" and it wouldn't teach to the end of the year test, either. Those may be roadblocks for
you.
Oh yeah, thank goodness your son doesn't seem to have severe issues. In all honesty, do you think he has problems learning
math, or has it just been
style issues? What do
you think the real problems are?
Best intentions,
Geo
