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 = 8^{2} + 1^{2}

= 7^{2} + 4^{2}.
- Second, 65 is the length of the hypotenuse of 4 different Pythagorean Triangles:

65^{2} = 16^{2} + 63^{2}

= 33^{2} + 56^{2}

= 39^{2} + 52^{2}

= 25^{2} + 60^{2}.
- Third, 65 = 1
^{5} + 2^{4} + 3^{3} + 4^{2} + 5^{1}.
- 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! …
