Dear Marshall,

Just wanted to thank you for the materials you posted (mostly the worksheets and coloring book). If you find the time, it would be great to hear about the math your daughter has been doing more recently. In other words, there are/were a couple of weird folks who enjoyed your blog!

Best,
Joshua
