"Thank you for the podcasts! I really enjoy the puzzles. This relates to the 5/29/15 podcast re: coin flipping game that was stopped before completion. The flips when stopped were two Heads and one Tail. You indicate that the options on next 2 tosses are HH, TH, HT, and TT. Since the game stops when one person reaches 3 points, wouldn't HH and HT be the same, as the second flip isn't needed? This seems to match your ultimate answer of 75% and 25%, though ... with the person with Tails only winning with TT, which is 25% chance. I get the same answer but intermediate steps differ. Am I looking at this incorrectly? Thanks!."

"This month we ran our puzzle and problem solving team competition amongst the different grades. We decided to improve from the traditional "hard maths" questions and have inquiry and thinking stations. This wasn't about who was the best at just Maths, it was about who was the best at doing Maths using all the MYP ATL Skills.

Thanks again to the fantastic Transum.org site for the puzzles I used to create the stations. To mention a few brilliant aspects about using this site for Maths stations.

On refreshing you get a new but similar puzzle, points are often generated, instructions included for staff to read and creative interactive levels you can adjust depending on the grade...Completely FREE!"
