First of all... Math Teachers at Play 34 is online... go check out the posts! Then... I'm doing a giveaway again... one of you, my readers, can be a lucky one to win a free Mastermind board game! Update: The winner is now chosen, the third commenter below, named Äiti. This went quick!!!!!! Comments are therefore closed. The lady who contacted me about it said that many of today's adults actually KNOW the game from their childhood, but don't know it's still available. I haven't played it as a child, but a few years ago I found Mastermind online (on several math games websites), and I found I like it! This is how Mastermind works: You need to guess the "secret code" of colored pegs: both the color and the order they are in. You make a guess, and your opponent (or computer) tells you some clues.

Recently I offered one of my customers a free book for finding an error in the answer key... she declined and wished someone else could have it who is in need. So I'll give one electronic copy of Math Mammoth Geometry 2 book (PDF file) to one randomly chosen lucky winner. To participate, you need to do two things: 1) Leave a comment in this blogpost, explaining how and where you'd use this book, AND 2) Email me so I have your email address. If you have no use for this geometry material, please don't participate, and let someone win who can use it. If I choose a winner who didn't email me, then I cannot contact them. In that case I will have to choose another winner. I'll first choose a few best entries based on how/where they'd use the book, and then choose randomly among those. This 'contest' closes and winner will be chosen whenever I notice (in checking my mail) that there are at least 10 participants. So hurry up!
