2014 Mathematics Game


The Math Forum's Year Game puzzle has returned for an eighteenth year!

Come challenge your students to write expressions for each of the counting numbers 1 through 100 using

  • the digits in 2014
  • standard operations
  • grouping symbols

Now taking place: math education conversation of the day

"There comes my problem. My function is long enough that even MATLAB cannot display it. Do you have a suggestion for me to do the optimization?"

100th Day of School


In the coming weeks, many students will be attending school for the 100th day this school year.

The 100th Day can be a lot of fun — and a teachable moment! Counting up to 100 for the 100th day of school gives teachers many special opportunities to investigate place value.

The discussions and links to Web resources found in the FAQ provide many ideas to make your 100th Day a memorable experience for your students.

Speak at Twitter Math Camp 2014


The free event that has reinvigorated math teachers in St. Louis and Philadelphia — and across the Twitterverse — is now seeking topics and speakers for its next summer gathering.

A shared, editable document for the presentations at Twitter Math Camp 2014 (TMC14) is open for your suggestions:


Type in a topic that you want to see, add a "+1" after other entries that interest you, and suggest speakers on teaching challenges that already include

  • intervention techniques and strategies for students who struggle in math
  • how to create opportunities for authentic proof outside of the traditional geometry curriculum
  • whiteboarding in the math classroom
  • formative assessment strategies
  • race and diversity: why it matters for teachers and why it matters for students

Submit your own proposal to speak at TMC14 by Monday, 20 January:


Want to share something short — between, say, five and fifteen minutes long? Check back at twittermathcamp.com to submit it as a "My Favorite" at a later date.

This conference "by teachers, for teachers" is "not about how to use blogs or Twitter or social media in the classroom. It isn't how to teach teachers to use social media to connect with each other. And it isn't centered around technology. It's really designed for math teachers in the classroom who are looking to become better, and who use the internets to talk about it and share resources and get better."
