The Programme for International Student Assessment (PISA) is a triennial international survey which aims to evaluate education systems worldwide by testing the skills and knowledge of 15yearold students. To date, students representing more than 70 economies have participated in the assessment. The most recently published results are from the assessment in 2012. Around 510,000 students in 65 economies took part in the PISA 2012 assessment of reading, mathematics and science representing about 28 million 15yearolds globally. Of those economies, 44 took part in an assessment of creative problem solving and 18 in an assessment of financial literacy. PISA is unique because it develops tests which are not directly linked to the school curriculum. The tests are designed to assess to what extent students at the end of compulsory education, can apply their knowledge to reallife situations and be equipped for full participation in society. The information collected through background questionnaires also provides context which can help analysts interpret the results. In addition, given PISA is an ongoing triennial survey, countries and economies participating in successive surveys can compare their students’ performance over time and assess the impact of education policy decisions.

Purplemath’s algebra lessons are written with the student in mind. These lessons emphasize the practicalities rather than the technicalities, demonstrating dependable techniques, warning of likely “trick” questions, and pointing out common mistakes. The lessons are crossreferenced to help you find related material, and a “Search free lessons” link is provided above the article title on every page to aid you in finding the math help you’re looking for.

The mission of Mathhelp is to break down the “math wall” that holds so many students back from achieving the success they deserve. Why do students struggle in math? Because they simply don’t receive the individualized instruction that they need. By providing every student with a personal math teacher, we give students the opportunity to conquer math, to build confidence in themselves, to continue their education, and to pursue their dreams.

This is a blog where a teacher has written some notes about math lessons and has given different interesting math task and problems for the students to make them more interested in math lessons. There are also links to other web sites where students can find similar problems and exercises and there is an option for comments to be put.

http://www.wikihow.com/Category:Mathematics
This is a site with tutorials where concrete given math problems from different math disciplines are solved. The examples are suitable for the students to learn how to solve other similar math tasks. The examples and the way they are solved are exellent for the students who has missed the same lectures in the classes. Not all math disciplines are covered.

This is for supporting teachers in prepareing lectures plans. There are also aditional matherials with math challenges and their answers for the students. Only for teachers in primary schools, but the idea is good for making such thing about teachers in secondary schools. Not all of the materials are with open access. https://www.khanacademy.org/math
Khan Academy is an online learning platform that provides teachers, students and parents with wide variety of educational resources. Teachers can search for a suitable topics in the following categories: Every category contains multiple subcategories with lessons made up of instructional videos, interactive practice problems and quizzes. The Khan Academy enables teachers to track students’ progress and give feedback based on students’ activity. On Khan Academy students can get support in what they are learning in school. Moreover, they can also start learning something new, completely not related to the curriculum. The platform allows to learn in one’s own pace. The website can be accessed from a computer using browser or via the application for mobile devices.

Real World Math is a collection of free math activities for Google Earth designed for students and educators. Mathematics is much more than a set of problems in a textbook. In the virtual world of Google Earth, concepts and challenges can be presented in a meaningful way that portray the usefulness of the ideas. Students will find downloads for over 30 activities, videos, and instructional tutorials for Google Earth & SketchUp. The goal is to take the math you learned in class and develop it further with problem solving activities. This is a modern approach to mathematics that is studentcentered and taskoriented; it embraces active learning, constructivism, and projectbased activities, while remaining true to the standards. Higher level thinking skills, such as analysis, synthesis, and creativity are encouraged as well as technology skills and social learning.

The video presents a maths lesson, made using traditional methods, like the blackboard and new technologies, like software Geogebra. The theorem proved is the most important topic for students of the 5th class who have studied the Integral calculus. The video was made by the students of the 5th year from Oreste Del Prete Italia.

Summer School of the Cyprus Mathematical Society on Problem Solving
Each year the Cyprus Mathematical Society offers a summer school of one week duration . It aims at enriching the mathematical content of pupils of ages from 10 to 16 years old and at improving their skills in the area, particularly in problem solving. The programme of the school covers lessons for strengthening and deepening mathematical knowledge and skills in various areas of school mathematics in combination with the provision of various pleasurable activities for developing positive attitudes towards the subject. Among the courses that are offered is a course on Problem Solving aiming at The course is based on the ideas developed in the Polya’s “How to Solve it”. And it provides various sets of problems for solution. Further information on the Summer School can be found at the webpage of the Cyprus Mathematical Society.

Student Institute of Mathematics and Informatics (УчИМИ) was established in September 2000, which was declared by UNESCO for World Year of Mathematics. The founders of (УчИМИ) are the Union of Mathematicians in Bulgaria (UMB) “Eureka” Foundation, International Foundation “Saint saint Cyril and Methodius” and the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences (BAS).
Each year (УчИМИ) sends an invitation for participation in its activities to students from 8 to 12th grade throughout the country. Every year for six weeks an international summer research school for students (RSI) holds at Massachusetts Institute of Technology (MIT) in the USA.Students from all continents participate in it. (УчИМИ) has two competition sessions – Student conference in January and Student Section in the Framework of the annual Spring conference of UBM in April. The deadline for sending projects for student conference is the beginning of December, and for the student section – at the beginning of March. Participation in the two competition sessions is independent. The authors of the best projects in the Student Section are invited to participate in a threeweek summer research SCHOOL in July and August and (УчИМИ) covers their expenses. The summer school is held two weeks in Varna and 1 week in the mountain in Usana. For 21 days the participants at the school combine work and entertainment. They attend educational lectures with eminent professors of mathematics and informatics every day for 45 hours. They have the possibility to communicate with professors and researchers dealing with actual problems of science. During the school each participant must prepare and defend a project in mathematics or informatics. All these activities are accompanied with sunbathing on the beach in Varna and on the Bulgarian Black Sea coast , excursions and hiking tours in the surroundings of Usana.
