I apologize for sending this message at such a late date. It is directed toward those flexible individuals in the DC area. ;->
There will be a workshop on fractions presented in DC by one of only two mathematics master teachers in Singapore on Friday, 11 December from 1 - 4:30pm. There are a few spaces available. If you are interested and able to participate, please email me: firstname.lastname@example.org
Again, my apologies for the late notification.
