The new Math Teachers at Play blog carnival is up for your browsing pleasure. Featured articles include activities and enrichment from preschool through high school:

Welcome to the 65th edition of Math Teachers at Play. First let us have some trivia about 65.

• First, 65 is the smallest integer that can be expressed as the sum of two distinct positive squares in two ways:
65 = 82 + 12
= 72 + 42.
• Second, 65 is the length of the hypotenuse of 4 different Pythagorean Triangles:
652 = 162 + 632
= 332 + 562
= 392 + 522
= 252 + 602.
• Third, 65 = 15 + 24 + 33 + 42 + 51.
• Lastly, 65 is the traditional age for retirement in the United States, the United Kingdom, and other countries including my beloved Philippines.

And now, let the math carnival begin! …
