"This is a maths resource that can be used to challenge pupils to complete a magic square, using only the numbers provided, to make sure that each row, column and diagonal all add up to the focused magic number. The resource provided challenges students to add up to 9, 12, 15 & 18, and could be used as a homework challenge, an additional classroom activity, or as a main activity within a maths lesson. Challenge pupils to work on two different methods for each magic number. This activity could be adapted with larger number, and other mathematic operations"

"Technology has inevitably been inserted to nearly all aspects of our lives today. First and foremost, the use of computerised cash registers have been around for a few decades now. Trying to remember cash registers which operated without a digital display might be nearly impossible. The generation which might be able to do so has been replaced with a new generation who depend on technology to a large degree. The dependence on new technology is starting to 'show signs' of the effect of converting from our analogue counterparts. Below is an example that I recently experienced the effect of technology in a transaction at a doughnut shop."

"A consortium of education organizations will be developing an online repository of classroom videos to help new teachers learn from master instructors how to teach math and science topics in third through sixth grades. The video repository is part of a project funded by a $3 million grant from the United States Department of Education and includes participants from Stanford University and the American Association of Colleges for Teacher Education (AACTE), as well as the Teacher Performance Assessment Consortium (TPAC), which AACTE helps to operate."

Maria Chudnovsky, mathematician, is one of 23 MacArthur Fellowship recipients in 2012. She is an associate professor in the department of industrial engineering and operations research at Columbia University and specializes in graph theory. With colleagues she successfully solved the "Srong Perfect Graph Theorem" which was proposed in the 1960s, and her research is potentially "deepening the connections between graph theory and other major branches of mathematics, such as linear programming, geometry, and complexity theory." A video featuring the awardee can be viewed on the web site.

"Developing a 21st Century Global Library for Mathematics Research discusses how information about what the mathematical literature contains can be formalized and made easier to express, encode, and explore. Many of the tools necessary to make this information system a reality will require much more than indexing and will instead depend on community input paired with machine learning, where mathematicians' expertise can fill the gaps of automatization. This report proposes the establishment of an organization; the development of a set of platforms, tools, and services; the deployment of an ongoing applied research program to complement the development work; and the mobilization and coordination of the mathematical community to take the first steps toward these capabilities. The report recommends building on the extensive work done by many dedicated individuals under the rubric of the World Digital Mathematical Library, as well as many other community initiatives. Developing a 21st Century Global Library for Mathematics envisions a combination of machine learning methods and community-based editorial effort that makes a significantly greater portion of the information and knowledge in the global mathematical corpus available to researchers as linked open data through a central organizational entity-referred to in the report as the Digital Mathematics Library. This report describes how such a library might operate - discussing development and research needs, role in facilitating discover and interaction, and establishing partnerships with publishers."

Abstract: "The principal aim of this study is to find the weaknesses of secondary school students at geometry questions of measures , angles and shapes , transformations and construction and 3-D shapes. The year 7 curriculum contains 4 geometry topics out of 17 mathematics topics. In addition to this , this study aims to find out the mistakes, 28 , 7th grade students made in the last 4 exams including two midterms and two final exams.To collect data, students were tested on two midterms and two final exams using open-ended questions on geometry to analyze their problem solving skills and to test how much they acquired during the year.Frequency tables were used in data analysis.To fulfill this aim in the first midterm exam the subject measures were tested.In the first final exam which followed the first midterm exam in addition to measures and angles shapes skills were also tested. Following these tests , in the second midterm we tested the students on transformation and construction. A descriptive methodology and student interview were used in the study to analyze and interpret the results. The results from this study revealed that 7th grade secondary school students have a number of misconceptions, lack of background knowledge, reasoning and basic operation mistakes at the topics mentioned above."

Was able to add up to 8 and understood 0 concept, features video but not of this experiment

Abstract: "An innovative mathematics game shown to be effective for low-achieving mainstream students is tested in special education for learners with intellectual disabilities. The game relies on a graphical, intuitive representation for numbers and arithmetic operations to foster conceptual understanding and numbers sense, and provides a set of 2-player games to develop strategic thinking and reasoning skills. The game runs on computers and interactive white boards, and as an augmented reality application at a science centre. We compare its use in special education and mainstream education with respect to usage, performance levels and learning gain. The game has been used by teachers in special educations, with gains in mathematical understanding, strategic thinking and communication skills as effects."

Dozens of online math manipulatives K-12

 ***** "The National Library of Virtual Manipulatives (NLVM) is a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis). The project includes dissemination and extensive internal and external evaluation."
