From the carpenter measuring lengths of wood to the physician checking a patient’s blood pressure measurements on a chart, we constantly use numbers and perform calculations to guide our actions and decisions. It has been shown that school-entry numerical skills are a more important predictor of subsequent academic achievement than early reading and socio-emotional skills.
What is Big Data, Anyway? at Open Source Integration Software Blog Big data is nothing new. Humans, helped by their computers, have been collecting massive data sets, since the dawn of times. Weather patterns, harvest yields, stock prices, geo-localization, searches, web browsing – the types of data are as broad as the needs of the organizations, large and small, in all industries, which collect mind-boggling amounts of data. A clear definition of big data is also difficult to pin down. What is big to one organization may not big to the next. As the name implies, big data is characterized by the size or volume of data records, but other attributes need to be considered, such as velocity, variety, or complexity.
What happens when all textbooks are (only) digital? Ask the Koreans! A few years ago, a World Bank study highlighted the fact that there simply aren't enough textbooks for most students in Africa, and what is available is too expensive. In response to this reality, some people at the World Bank have been exploring various options for addressing the 'textbook gap', including initiatives investigating the potential cost-effectiveness of 'e-books' for African students. At the other end of the spectrum from the situation that exists in schools in many low- and middle-income countries in Africa, students in one East Asian nation may soon not have access to textbooks either -- at least the old fashioned, printed kind. This blog periodically checks in with what is happening in Uruguay, as one way to help explore answers to the question, What happens when *all* children and teachers have their own laptops? That said, in no other education system (that I know of) has there been serious talk about getting rid of paper textbooks entirely.

Using Ten-Frames to Understand Numbers from 11-20 You’ve simply gotta love it when an observation lesson goes way better than you could have expected! Today I was getting ready to work with my Firsties when my AP showed up for my observation. Yesterday, the students were working with two ten-frames to build and better understand numbers from 11-19, and I had several goals for the continuation of the activity:Students will realize that to fill a ten-frame, they don’t have to count by ones–if they fill it, it’s 10Students will be able to count on from ten for a number from 11-20 (eg., 10…11, 12, 13, 14)Students will be able to write numbers from 11-20 in expanded form showing the value of the tens and ones (eg., 14 = 10 + 4) As the students came in, two ten-frames and a small pile of counters were on the table at their seat. I told the students that I had meant to give each of them 20 counters, but I hadn’t had time to count.
50 QR code resources for the classroom As mobile learning and technology is more readily integrated within classroom settings, QR codes can be used as an interesting method to capture a student's attention and make lesson material more interactive. Quick response codes, also known as 'QR' codes, are simple, scannable images that are a form of barcode. By scanning a QR code image through a mobile device, information can be accessed including text, links, bookmarks and email addresses. In the classroom, QR codes can be used in a variety of ways -- from conducting treasure hunts to creating modern CVs. Below is a number of articles, tutorials and lesson plans designed to help educators. UNESCO Mobile Learning Week presentations The First UNESCO Mobile Learning Week in partnership with Nokia and held at at UNESCO Headquarters in Paris, France, aimed to facilitate discussions on how to use mobile technologies to transform educational processes and outcomes. Officials from Ministries of Education, international experts and practitioners in mobile learning, as well as representatives from major partners in the field presented their ideas on using mobile technologies in education to help achieve the Education for All goals and improve the quality of education.
