"Are you already familiar with Mystery Number Skype? If you are, read on. If you're not, my six and seven year olds would be happy to tell you how to play it. I love the way Mystery Number Skype helps students to think about numbers. Every time we play, the game changes and a new strategy and order of questions emerges that can help the children narrow down the options for the number the other class is thinking of. It's such a great tool for me to see their thinking and for them to try various number strategies."

"The Ancient Greeks loved algorithms, and devised lots of useful ones. One of the most famous is the Sieve of Eratosthenes. It is a way to find prime numbers, special numbers that are also known as the atoms of numbers. Prime numbers now form the basis of our most powerful encryption systems upon which digital money is based. Our electronic banking systems (and lots more) would collapse without prime numbers. You can use the Sieve of Eratosthenes as a way to practice times tables, spot patterns and explore how to improve algorithms, whilst also uncovering these mysterious, magical numbers with no obvious pattern of their own. Here you can follow in the footsteps of Eratosthenes and develop your algorithmic thinking skills."

"I just learned from Tony Vincent that Math Tools iPad app is now free for a limited time. It used to cost $4.99. Math Tools is a great Math app that is designed specifically to cater to the math needs of kids and preschoolers. Math Tools comprises a collection of familiar math learning tools that allow young learners to: Learn to count Practice addition, subtraction, multiplication, division and times tables Develop an understanding of number ideas and number values Create number bonds Learn to use and practice multibase and number bond theories Challenge themselves through setting numbers and operations to create complex equations"

Many mobile users in India have been receiving missed calls from premium international numbers, or calls related to winning lotteries, prompting them to call back and waste a much of their prepaid balance. TRAI (telecom industry regulator in India) has asked all operators to stop ISD calling on prepaid numbers until especially asked for by customers. TRAI says that it has been receiving complaints that people are getting missed calls (wangiri calls) and calls relating to winning prizes or lotteries from international numbers. These are often premium numbers charging high tariff, prompting consumers to call back such numbers. By responding to such calls/SMSs consumers have to pay unintended charges.

"Say you're trying to solve a sudoku. You look at the various numbers that fill the squares and begin to work your way through the lines and boxes bit by bit, adding values and searching for any unused digits. If the puzzle is easy, you may be able to brute-force a solution. But what if the sudoku is a bit more challenging? As you look at the puzzle, you may notice how numbers seem to be arranged just so. A number here, a number there… In fact, by recognizing the arrangement of the numbers, you're able to solve the sudoku lightning fast. What's going on? It's all in the pattern."

"If you like the language of numbers ( I bet qualitative researchers do ) then the infographic below will be of great interest to you. It features some interesting facts about the state of education in the world like the number of students, number of teacher in pre-k to high school...etc. I am sharing with you this infographic first because the data it contains is really amazing and second because this work has been realized by Microsoft Education which is a reliable source ."

"A great management tip for school or class sets of iPads, tablets, and iPods is to number each device. Setting the lock screen wallpaper to an image with each device's number will make it easy to identify devices. Just press the home or power button and the lock screen instantly lights up and displays the number. "

"The students in Molly James's kindergarten classroom were tasked with creating a mathematical art gallery. They had each drawn a number and then searched for two types objects they could use to compose a visual number sentence - such as two rulers plus three scissors to equal five objects. After photographing and mounting their pictures on the wall in numerical order, the students sat on the floor with their sketchbooks and began to draw and talk. "I had expected them to learn something about number composition," James said, "but I didn't expect the remarkable observations they began to have about the photographs." For example, when one girl looked at a picture of two red scissors and three blue scissors (2+3=5), she noticed that the direction of the handles gave rise to a new number sentence: 4 scissors pointing left + 1 scissor pointing right = 5 scissors. James, who recently published a paper about creativity in the classroom, said moments like these remind her that "creativity is not fluff or an add-on, but is instead an essential part of what it means to be a mathematician."  In fact, she believes creativity is the key to helping her students become confident and skilled mathematical thinkers."

"Helping children visualize math is critical to their success in the subject. I recently observed a 5th grade class starting a lesson on area and perimeter. I turned to a girl who was in my class four years earlier and reminded her that she knew the topic. "Yes I do!" she said excitedly. "The perimeter is where you sit along the outside of the rug in morning meeting, and area is the inside of the rug, where the squares are. That's from 1st grade," she said confidently, circling her fingers in the air to represent her thinking. Visual cues, like this one I use with my six- and seven-year-old students, stick and show that envisioning math helps children learn in lasting ways. We teachers can do more to give students internal ways to see the structure of mathematics-to understand types of units and what it means to move between them, and to pull apart and combine numbers. But math instruction is changing. At my school, in the early grades, we encourage children to use their fingers, something that feels so natural to them, to better understand numbers and the numbering system. We might talk about how a "high five" involves using a whole hand, which is really a unit made up of five fingers; while a thumbs-up involves just one segment of that five-part unit. We then go on to using things like beads on a string and, later, place-value disks, which are like poker chips, to help children see and work with numbers, units, and place value."

"Recently, I wrote about the latest updates for iMovie, iPhoto and Garageband. However, the iLife apps were not the only apps to get a refresh. Pages, Keynote and Numbers also received important updates. These touch optimized office apps are default apps for a lot of iPad schools, simply because they are great for creating digital content. So, in this post we take a look at just what you can expect in the latest updates for Pages, Keynote and Numbers."

"It took just one relentless bout of the flu to remind me of the power of empirical evidence and the importance of shooting data. More than numbers, it was the evidence gleaned from my experiences and the images that I gathered along the way that helped my doctor solve the riddle that was delaying my recovery. My kids thought I was crazy, but I took some photos to save the evidence, and my doctor appreciated this. Gross? Absolutely. Helpful? Definitely! The doctor said that the pictures inspired him to take a different approach in my treatment. "Good data gathering," he joked, and I smiled, recalling one of my greatest pet peeves: educators and parents who rant about their disdain for this very important work. To listen to some, you'd think data are only numbers that shady reformers crunch in order to cash in on imaginary problems created by incompetent teachers. This is a dangerous assumption. The fact is that data are information that matter, and if they don't matter or if the conclusions we reach aren't helping us solve important problems, then we need to change the data we're collecting and the way we approach analysis. After all, isn't it a bit silly to blame data for our own faulty decision making?"

"What strategies are you planning for building number sense and problem-solving skills this year? Check out our Number Talks collection to see a daily, short, structured way for students to talk about math with their peers."

We teach children about numbers, but how do people come to know what numbers are, given that they are abstract? There must be some process of learning that takes place. This paper explores this problem, offers several alternative accounts of what a number is, and argues that the concept of a number can be learned by learning to recognize the size of a set or collection of entities. Teachers call this subetizing

"As computer science skills like coding become increasingly relevant in the job market, a number of states and districts are making moves to set students up for success.  Today, 25 states require students to take a computer science course in order to graduate from high school - more than double the number with such a requirement in 2013. Additionally, a large number of districts are weaving coding instruction into early learning curriculum, impacting students as young as kindergarten."

"Making the ordinary extraordinary… This picture was one I picked up a couple of years ago on Twitter and it sparked a creative note. Having experimented with the approach to place value and reading numbers in this way it has very good effect. Especially when the students make the tool themselves. Younger students can get to grips with the position of numbers and the zeros prompt them to say the correct magnitude if they are a little unsure. You could write the words too underneath the numbers if necessary. Its a lovely class project for year 3 and 4 and it's cheap too. It is also great for intervention at a later stage, with older students."

Facts about the numbers 0 - 9999

"A group of children on a playground, each kid clutching a slip of paper with a number on it, moves along a line drawn in chalk, comparing numbers as they go and sorting themselves into ascending order from one to ten. Another group of children, sitting in a circle, passes pieces of fruit - an apple, an orange - from hand to hand until the color of the fruit they're holding matches the color of the T-shirt they're wearing. It may not look like it, but the children engaged in these exercises are learning computer science. In the first activity, they've turned themselves into a sorting network: a strategy computers use to sort random numbers into order. And in the second activity, they're acting out the process by which computer networks route information to its intended destination. Both are from a project called Computer Science Unplugged, which endeavors to teach students computer science without using computers."

"English grammar is a topic that actually frustrates a number of people. Irrespective of learning level or nationality, spelling and grammar error seems to confuse a lot of individuals. And in case anyone has a learning debility such as dyslexia, using accurate grammar looks like a terrible task. Using grammar correctly could be challenging may be not for those who are English native speaker, but surely for those who learn English from scratch. English language and its difficulties can be very much puzzling. Although, a dictionary or software can assist learners but it cannot give accurate answer. In fact, word processing programs are not very much effective in correcting grammar errors completely. Now, the question is how one can improve or nourish their English grammar skill? With the advancement in the technology, there are a number of tools that might help those struggling to improve their grammar. Web technology has actually contributed a lot in this through the ease of access. Today, you can find a number of tools, apps and websites available over the web that helps in learning and improving grammar from scratch. Here is a list of top ten websites for teaching or learning grammar lessons."

"With the recent announcement that Google Classroom will be available to all Google Apps for Education schools by the week of August 11th, schools that have also adopted iPads are interested in exploring the platform to determine if it will integrate into their existing deployment to provide a helpful and approachable workflow solution. While there are currently a number of workflow solutions and Learning Management Systems that work well with iPads, Google Classroom will likely become a top contender for iPad classrooms because of the integration with both the Google Drive and Google Docs iPad apps as well as any number of iPad creativity apps. While there is not an iPad app for Google Classroom, the web interface works seamlessly and allows students to turn in any assignment or file that is in their Google Drive account as illustrated by the video below."

"As you may remember from your own (in)glorious youth, most university students are required to take a statistics course even if they hate math and aren't in a particularly numbers-heavy major. Ellen Peters, a professor of psychology at Ohio State University, heard this was driving a lot undergrads on her campus crazy. "A lot of the students are really threatened by it. They're kind of afraid of it, they dread taking it," she says. "If they do dread it, they can end up in a cycle of failure." Curious to see if she could make a positive change among math-phobic Buckeyes, Peters created an intervention that tested whether or not value affirmation could improve student's comfort and ability with numbers, otherwise known as numerical literacy or numeracy. The results, which were published Wednesday in the journal PLOS ONE, indicate that confidence and core values have a lot to do with learning the numbers."
