 Posted: Sun Dec 05, 2004 11:09 pm    Post subject: Most lessons in EM are set up so that the students can discover or explore concepts before actually teaching strategies. Take the ballpark estimates for example. We are asked not to initially show the children how to round and then later we can show them a more formal way of estimating. I think that we are supposed to see how the students solve the problem first then show them a formal way. I know many parents are at first confused and frustrated by partial sums. I explain to them that partial sums teaches students the actual value of the digits and shows students all the steps involved in adding, not just the short cut. I've found that partial sums also helps the students learn subtraction easier too, because they actually understand the relationship of the numbers and what each digit stands for. I hope this helps in some way. Good luck!

 Posted: Mon Jan 24, 2005 1:12 pm    Post subject: partial sums and parents Most of my students are doing well with the partial sums algorithm. Now we have moved on to trade first and I am finding that quite a few of my students are trying to do partial sums for subtraction. Any helpful hints out there to correct this mistake?

Parents don't always understand the things we do and why. I think the now that we are all teaching EDM things will be getting easier. If my students don't use partial sums when they are supposed to I have them re do it. I also really emphasize that they are the "teachers" and they are supposed to teach their parents, because most parents don't know about this way to add. The kids seem to love being the teacher. Good Luck!
