Annual ASSM, NCSM, and NCTM – A Week of Math Ed Leadership & Collaboration

DSCF3247

Just returning from a week of fun in San Antonio where the annual math leadership and teacher conferences were held. Casio was a proud sponsor of a few events and at NCTM we had such a blast showing off our new graphing calculators (both approved by College Board for use on the PSAT, SAT, & AP exams), the CG-50 Prizm and the CG-500 Prizm CAS (3D graphing anyone?!) Not to mention the added bonus of blowing TI out of the water! (Side note: I will be doing specific posts for each of these in the next couple of weeks showing off some of the new and exciting features).

Thought it would be fun to highlight some of the moments we had sharing math education and technology with the dedicated math leaders and teachers we met throughout the week.

ASSM & NCSM


For the second year, we were honored to sponsor the opening session of ASSM (Association of State Supervisors of Mathematics). Mike Reiners, one of our amazing math teacher leaders and Casio user from Minnesota, provided some technology talking points after the main speaker and then everyone enjoyed some good food and conversation.

DSCF3005At NCSM (National Council of Supervisors of Mathematics) we were able to connect with many math leaders at our exhibit booth. We had a great time sharing our new calculators at our Showcase workshop and everyone walked away with a brand new CG-50 prizm to explore

 

Benjamin Banneker Association Reception at NCTM

It was a privilege to sponsor the BBA Reception at NCTM for the 2nd year in a row. What a great group of math educators who work so hard to ensure equity for all students. We were excited to continue our scholarship for a deserving student to support their future education endeavors.

NCTM & The Calculator Face-Off Challenge

NCTM was a big endeavor, with game-show stage and podiums, screens, lights, calculator displays. Thanks to the amazing team of Chris and Lionel from Events Special Effects and our own Casio Exhibit gurus John and Jason, the vision was made into a reality and it was a pretty beautiful booth if I do say so myself. Kudos to the team – it’s hard work designing, building and creating everything, but they did an amazing job. Some behind-the-scenes photos:

We had some crazy fun at the booth with hourly game-shows, and T-shirt spotter program where we gave away Kindle-Fire to those spotted in our t-shirts. We had G-shock watch giveaways, calculator prizes for our volunteer contestants and a magician, Mark Paskell, doing some magical give-aways and tricks. (My mind is still blown away by the reproducing bunnies….) 

We loved all the connections and interactions we had with math teachers, showing offthe amazing capabilities of all our calculators, but definitely our newest CG-50 and CG-500 graphing calculators. The look on our game-show participants faces when our CG-50 just blew the TI competitor out of the water was priceless. I know I am excited by the number of converts!

Here is a slide show highlighting some great moments from the games, demonstrations, sharing and talking with math educators, winners of our T-shirt spotter program, and some magic as well. Thanks to all the great math educators who came by and participated! Big shout out to our Casio teacher contestants, Jennifer North Morris, Tom Beatini and Mike Reiners.

Playing Around with Data

Brothers Sisters Casio ActivityI’ve been exploring the different types of graphs that can be constructed using data lists and the Casio graphing calculators. Data collecting is a powerful way to help students use mathematics in a real-world context. It provides students the opportunity to collect data that is interesting and relevant to them, and then make decisions about that data, such as what graph best supports the data, what questions can we answer from the data, what predictions, if any, can we make, etc. Students apply so many mathematical skills when working with data. What to do with the data once it is collected is obviously a major part of the process, and being able to visualize the data to help answer questions requires students to understand what the different types of graphs mean and show about the data, and, depending on the question asked, which graphical representation is best.

To help me in my exploration, I used one of the activities from our Fostering Mathematical Thinking in the Middle Grades with Casio Technology resource book (Dr. Bob Horton, 2013), as it has some great real-world activities and sample data that allowed me to explore a variety of graphs. Casio calculators can create many graphical representations from a single set of data. All the calculators function the same way, so that’s nice – if I know how to use one, I know how to use them all. Obviously, the Prizm, aside from color, also has some extra features, but no matter which graphing calculator you have (9750GII, 9860GII, Prizm), you can create all these different types of graphs and statistical representations.

The activity I chose, Brothers & Sisters, is one where the data collected from the students in the class is the number of siblings they have, and the two lists created are the numbers of siblings (0 – the highest # in class) and frequency of each.  From this data, we explore box plots, pie graphs, histograms and then measures of central tendency. I have attached a PDF of the activity at the end of this post for those of you who might be interested in trying it with your own students. It includes the keystrokes for the Prizm, but as I said before, all Casio graphing calculators use the same keystrokes, so even the $50 version can do powerful things.

I am not going to explain the whole activity, since I have attached the PDF that you can peruse at your own leisure. But, I did create a short video clip using the 9860GII version of the graphing calculator, to show the steps. I started with sample data already entered so that I could get right to the various graphs more quickly.

Start playing with data with your students, if you have not done so already. Provide students an opportunity to collect their own data, make decisions on how to represent and use the data, and see how much math happens!
