Erik van Haren is a math teacher, tutor, and coach in the Netherlands. He not only teaches students about the fun and wonders of math to kids, but also coaches math teachers to help them improve their own practice and use of games and fun activities in their own math instruction.
He runs workshops and a blog, so if you’re interested in ways to engage students with math, go and check it out.
Also, he sells math games and activities through his website, including Mathemagician’s Duel! If you’re in Europe and want to get Mathemagician’s Duel, but don’t want to pay the shipping from Canada, maybe you can get it from Erik at Mathplay!
