DD7 does Redbird math and I just received this email from them. Here's an excerpt:
"As a valued member of the GiftedandTalented.com family, we wanted to let you know about a difficult decision we recently made. Due to changing business dynamics, we have decided to close GiftedandTalented.com, and beginning July 1, 2018, our products and services will no longer be available."
So I guess we'll be cancelling after dd finished this level. Too bad. She was liking it.
