Earlier this week, I sent out my last Playful Math Newsletter to email subscribers.

Most months, my newsletter includes tips and activity ideas for playing math with your kids. But from time to time, I give away a free sample of whatever I’ve been working on — an early draft of something that will eventually show up in one of my books or printable activity guides.

This month’s gift was a Pentomino Puzzle Calendar, a daily adventure in spatial reasoning.

And if you hit “Reply” to your welcome email and ask for a printable Pentomino Puzzle Calendar of your own, I’ll send you one right away.
