Karim Logue, friend of the blog and proprietor of Mathalicious, has opened up shop. He’s attempting to go at it alone, creating and selling interesting, high-quality math curricula on his own label, an experiment I’ll be watching with a lot of interest. Going in his favor is the fact that he has a sharp eye for applied math and a strong hand with slides, worksheets, photos, and videos. I’ve been previewing his fall line and it’s super. He’s offering my readers a 20% discount on the annual subscription with the code “dy/dan” between now and September 30. So check him out. Check out the freebies and then spring for the costies. Your kids will thank you.
