Thanks Dottie! DS has been in it since KG (they start on 1st gr EM in KG) so he is probably in 3rd gr EM now (I guess; he is in 2nd gr). DD also started KG this year so she has EM for 1st. Our school is K-8 so I guess some of the kids start to outgrow EM by 4th with some outgrowing it even earlier. I don't know what else we use after that. Again, thanks for sharing your experience. One last question: did DD, DD and DS have to memorize their multiplication at some point to progress through EM?
