I've been buying unusually creative and uniquely fresh, critically thinking educational and play products from Timberdoodle for over 20 years. When they first began to sell these dot- to-dot books, I ordered them in large numbers and haven't stopped yet. Now that my own children are grown, I buy them for my grandchildren and classroom students. I haven't met a child yet who doesn't love these books. I purchase several each year. Thank you, Timberdoodle. My students always ask me where I get all these exciting products--which they only perceive as fun. I keep telling them to visit Timberdoodle.com.
