I’m a math educator at the Math Forum @ Drexel University. “Math educator” is a purposefully open-ended label. I write problems and supporting materials for our Problems of the Week, observe, mentor, coach, and develop PD for teachers in grades K-12, teach *Problem Solving in Geometry and Measurement in Grades 3-8* as part of the Math Forum’s online PD program and two electives in Drexel’s Mathematics Learning and Teaching Master’s program (*Teaching Math with the Geometer’s Sketchpad* and *Learning and Teaching Calculus with the Geometer’s Sketchpad*, both of which are also available as Math Forum online PD), occasionally tweet as @MFAnnie, speak at conferences and workshops, and ride my bicycle to work as often as I can.

How areyou doing? I see you are still with math forum. Are you able to visit the classroom and do a lesson? I am at the new King School on Brunswick Avenue. Annie do you have any info on T-Test? Thanks for you help. I need an exact formula so I can slot any data into the formula. I know how do the standard deviation, but is that formula (SD)in the T-Test formula? Thnaks in advance. Come see me this school year I am in Room 174!

Hi Annie,

Thanks for speaking with me at the conference on Saturday. I subscribed to the POW, and am in the process of implementing the process in my classroom. I have several questions. First, I am putting together two separate questions for my upcoming lesson on converting customary units. I’m trying to create them so there are multiple problem-solving strategies possible for each. Here is what I have so far:

1. A faucet drips every 2 seconds. What strategies would be appropriate for this scenario. Do you have suggestions to make the scenario applicable to more strategies?

2. One container holds 3 gallons. Another holds 20 quarts. Jon would like to drink 4 gallons. Strategies? Suggestions?

Also, for the fruit scenario Suzanne posed on Saturday, what strategies are appropriate? I’m doing that one with my students now.

Thanks so much!

Jon

Annie — We love the Youtube Video of your Noticing and Wonderings presentation! I’m hoping you will have more ideas and thoughts to post on your blog about it soon! Thanks!

Hi, Beth. I’m glad you liked it! I’m thinking that the beginning of the school year would be a good time to revisit that idea, and then maybe some of you who have seen the video can share some specific ideas that you’re hoping to use. Look for that post soon!

Dear Annie,

As a proponent of math education in the United States, we need your help to promote our nationwide math competition by blogging or posting about it on your blog/forum.

As you probably already know, despite the fact that the US spends the most money on education per capita, our students are ranked 25th globally for math proficiency. The MATHCOUNTS Foundation is a nonprofit dedicated to improving that statistic. MATHCOUNTS’ third annual “ Math Video Challenge” is a math competition for 6th to 8th graders that encourages student innovation as they create and star in their own math videos, thus exciting them to pursue higher education in math.

As the webmaster of The Math Forum, we are asking you to help support this effort by mentioning us in your next blog or forum post or promoting our logo with a link to the site. So far this contest has gathered over 500

submissions and millions of views on the videos. Our goal this year is this year is to do even better. With your help, we are confident we will reach this goal.

For more information on MATHCOUNTS or the Math Video Challenge, visit our webpages at mathcounts.org and videochallenge.mathcounts.org/math-camera-action.

Respectfully,

Jake Byrnes
