Math Blog Carnival 101Welcome the 101st Math Teachers At Play Blog Carnival (MTaP)! If this is your first experience with the blog carnival, a little background information is in order. MTaP was started by Denise Gaskins over at Let’s Play Math.  It’s a collection of blog posts from teachers around the internet. Notice that these teachers are at play. This is supposed to be the fun side of teaching math. The last carnival was hosted at Three J’s Learning. You can find the current edition of our partner carnival, edition 138, at the Carnival of Mathematics.

Keeping with tradition, some curious facts about the number 101:

  • 101 is the 26th prime number
  • it is the smallest prime that is the sum of a square and its reverse: 100 + 001 = 101
  • 101 is the sum of the consecutive primes 13 + 17 + 19 + 23 + 29
  • it is part of the Pythagorean triple 1012 = 202 + 992
  • in physics and chemistry, 101 is the atomic number of mendelevium,
  • Room 101 houses the Ministry of Love, in the novel 1984 by George Orwell, and a is radio series based on that room,
  • there were 101 Dalmatians,
  • 101 is a term used for introduction such as English 101,
  • a brand new checking account starts with 101.

101 is a prime and it’s a twin prime as well. This is a fantastic documentary on twin primes and Yitang Zhang.

Wikipedia has a great visual for the Sieve of Erasthones, which will help you find all the prime numbers between 2 and 120.

Paul Stepahini writes about the spill test for prSpill Test imes and he includes some fantastic visuals.


Ben Orlin, from Math with Bad Drawings, makes an argument for which number is the loneliest number.


Simon Gregg, from Pinkmathematics, provides us with an excellent lesson on prime factorization with factor trees.



Without further ado, all the rest of the posts in this month’s blog carnival:

Brandon Smith redeems dear Aunt Sally in a blog and video about PEMDAS, over at the MIND Research Institute Blog. 

Susan Carpenter is making How to Multiply Books at Susan Carpenter’s First Grade Classroom.

Over at Learners in Bloom, Lilac Mohr started an online book club with Math and Magic in WonderlandShe recently finished the series, but I’ve linked to the beginning. When you scroll all the way down, you can see the entire series schedule with the topics covered.

Julie, from fractionfanatic, shared a quick game to help students practice mental math on the fly. It takes very little prep, can be put together quickly, you just need to adapt it to your students.

Denise Gaskins talks KenKen puzzles that are delivered to your inbox every Friday. According to Denise, KenKen arithmetic puzzles build mental math skills, logical reasoning, persistence, and mathematical confidence. She also offers advice for the homeschool parent ready to pull their hair out over math.

Crystal, from Triumphant Learning, talks about the importance of doing word problems.

The blog My Little Poppies has provided us with 4 blog posts for homeschoolers and non-homeschoolers alike. We’ve got 10 Ways to Keep Math Fun, Math Picture Books – we have several of these in our library, plus games and more games.

Malke, author of  the newly released book Math on The Move and Socks are Like Pants, Cats are Like Dogs, discusses the difference between memorization and learning and the problem with memorization alone.9780325074702

Over at Play Discover Learn, Lacy is discussing the difference between arbitrary and necessary, which follows Malke’s post about memorization very nicely. In a follow-up post, she shows what this looks like in practice as she works with her students on the Grapes of Math. 

The mathrecreation blog shares a wonderful post on the Islamic geometric patterns of Eric Bourg. Complete with color images and instructions on how to create this type of pattern for yourself and Dan also created some of his favorite spirals by plotting them in Desmos.

shp0485Math picture books keep coming up. In honor of the #MTBoS’s (Math Twitter Blog-O-Sphere) very own Christopher Danielson’s new book Which One Doesn’t Belong?, Math Hombre has provided his list of favorite math picture books.

Dan McQuillan, from his blog at Norwich University, makes a case for integrating calculus and challenging the current first course in calculus. 

Mardelee at Math-n-Science=Wahoo is talking exponents with grade 8 and Algebra 1 students.

At the blog Life Through A Mathematician’s Eyes, we’ve got a wonderful post about curiosity and asking “what if” questions. I think that goes well with Lacy’s post above about arbitrary and necessary. And another post about using a graphical model for teaching math with, of course, graphics.

I enjoyed this post from Zeno’s Meatball, which is a blog run by a 6th grader, Math Daughter, and her father, Win Smith. Math Daughter takes a trip to a Denver machine shop to visit with the creators of Zoomtools. 

Talking Stick Learning Center has taken math play and turned it into a group outdoor activity with Rational Tangles with 12 and 13 year olds.

Stacy, from A Moment In Our World, has provided a Catch the Flies Math Game printable.

multiplication-island-9-1024x764Natalie from Living With Kids Rocks, made up with great game to teach her children the basics of multiplication using play and base ten blocks.  She’s got this whole teaching through play thing down.

Crewton Ramone is teaching math to preschoolers by building a house for a duck.

And at one of my new favorite blogs, Math Coach, Rupesh has posted a wonderful conversation in which he leads the student to discover his own mistakes. This also fits well with Lacy’s post on Arbitrary and Necessary. He’s also given us a couple of posts on fractions:  part 1 and part 2.

This concludes this issue of the Math Teachers at Play blog carnival. I have read every post on this page and had fun doing it. I have so much to learn, and a lot more picture books to read, and definitely more things to play. If you are interested in hosting the carnival or submitting your own post, please contact Denise Gaskins creator of Math Teachers at Play.
