This Thursday, March 14 (3-14), is Pi Day, a day celebrated internationally by mathematicians. Pi is the ratio of the circumference of a circle to its diameter and represents a constant, infinite number, beginning with 3.14159. Pi has been calculated to more than one trillion digits, and Pi Day is celebrated in a variety of ways, including eating pie and reciting the number to as many digits as is possible to memorize. Various websites are dedicated to Pi Day. If you want to learn more about it, you may want to visit the site 36 Surprising Facts About Pi. You might also be interested in the site Find Your Pi Day. On this website, enter your birthdate (or any date), and the website will locate and highlight that date sequence in Pi. Learning more about Pi Day is a great opportunity to discover more about math--and to eat a slice of pie!

Stanford History Education Group hosts a website filled with US and world history lessons and assessments that are free for teachers to use to supplement their existing curricula. Their goal, as their website states, is "to improve education by conducting research, working with school districts, and reaching directly into classrooms with free materials for teachers and students." The history curriculum and assessments have been downloaded more than five million times. The Stanford Group is comprised of Stanford faculty, graduate students, and visiting scholars, and they are continually adding more content to their offerings, including recently released Civic Online Reasoning assessments and soon-to-be-released digital skills materials. If you teach and/or love history, you may want to explore this website.

Many of you may be familiar with TED Talks and have enjoyed the topics presented. TED also has an educational component called TED-Ed. The TED-Ed lessons focus on all subject areas and contain videos, quizzes, enrichment resources, and discussion questions.  Teachers may also customize lessons to meet their own classes' needs. To use TED-Ed lessons, teachers need to create a free account. Once registered, they will receive weekly emails containing links to that week's lessons. As a former English teacher, one of this week's lessons caught my attention: "Why should you read Shakespeare's The Tempest?"  To get a taste for what a TED-Ed lesson is like, watch this video and visit the accompanying lesson.  To be able to view all the materials, be sure to register for an account.

For anyone interested in exploring new learning or supplementing current courses, cK-12 may a website to explore. According to their website, they "believe every child . . . should have equal access to great education." With that goal in mind, they have developed interactive lessons for math, science, English and other topics, for the K-12 student audience. Lessons include videos, interactive activities, and online FlexBook textbooks. All materials are free for students to use and are compatible with a variety of platforms, including Windows, Mac, and mobile devices.

The New York Hall of Science (NYSCI) is a non-profit organization dedicated to offering interactive science to, as their website states, "schools, families and underserved communities in the New York City area." In addition to directly serving the New York City area, they have also created a suite of free iOS apps available to anyone that blend science, art, and gaming to encourage interest in STEAM.  The suite includes: Picture Dots, Playground Physics, Volumize, Fraction Mash, Size Wise, and Choreo Graph. Their goal is to inspire educators and students to explore math, science, and art and how they interconnect. The apps are available through the App Store.

Winter is a great time to continue learning through STEM-related activities. The cold and snow provide unique opportunities to try different experiments. I recently read an article called Cool Hands-on Learning that focused on winter STEM activities. The activities are designed for various age and experience levels, and as such, provides something that almost everyone can enjoy. If you're interested in any component of STEM, you may want to read this and try some of the activities.

I recently read an article in Tech & Learning about the top ten educational technology trends, and I found it quite interesting. At Seneca Valley we are involved either broadly or in specific classes in at least seven of these trends: 1:1, mobile devices, cloud computing, collaborative computing, robotics, game-based learning, and STEAM/STEM. Anyone interested in learning more about the educational philosophy behind the trends may find it worthwhile to read the article.

The old adage, "Practice makes perfect," is certainly true when it comes to writing. The more practice a student gets, the better writer he/she will become. Writer Igniter is a website that randomly generates writing prompts to give students ideas for practicing their writing skills. Just click the Shuffle button and watch Writer Igniter randomly select a character, a situation, a prop, and a setting to get students started writing. This tool could be used daily, weekly, monthly--however the teacher chooses--or students could use it on their own to refine their skills. Either way, it's a great writing tool and easy to use.

I recently watched this recording of a TED Talk about visual intelligence and how learning to look carefully can be an asset in many occupations.  Although technology isn't mentioned specifically, I believe the skills mentioned could absolutely be important for anyone who uses or works with technology. How can we be sure that the website we're using is real and not trying to scam us? How can we be sure that the email we received with an embedded link is really from who it says it is and not from someone trying to get us to download a virus or spyware on our computers? We need to look again and look slowly as the TED Talk suggests. There are always clues if we take the time to look. 

Online dictionaries are plentiful for anyone wanting to look up the definition of a word, but have you ever wanted to use a particular word and not been able to think of it? The Reverse Dictionary was designed to help people in exactly that situation. According to their website, "This reverse dictionary allows you to search for words by their definition." To use the site, type in the definition of the word that you want and click the search icon. The Reverse Dictionary searches other dictionaries to find words that match your definition. You can click on the words in the list that is generated to see their specific definitions.
