A+ Click helps students become problem solvers. No fees, no ads, no calculators, and no sign in. The website features a graduated set of 5000+ challenging problems for students in grades one through twelve, starting from the very simple to the extremely difficult. The questions are based on the Common Core Standards in Math and go beyond by adding hundreds of meaningful practical problems and brainteasers. The questions concentrate on understanding, spatial reasoning, usefulness, and problem solving rather than math rules and theorems. The problems include a short description and an illustration to help problem solvers visualize the model. The problems can be solved within one minute and without using a calculator.

The Klein Project blog is a collection of vignettes written for secondary school mathematics teacher. The blog is unique in the sense that unlike other blogs for teachers, “the vignette is not about pedagogy, but inspires good teaching. It is not about curriculum, but it challenges teachers to reconsider what they teach. It is not a resource for classroom use, but source of inspiration upon which teachers can draw. The goal is to refresh and enrich teachers’ mathematical knowledge.” Each vignette starts with something with which the teacher is familiar and then move towards a greater understanding of the subject through a piece of interesting mathematics. It will ultimately illustrate a key principle of mathematics.

The Project Maths in Ireland
The “Project Maths” aims at the provision of resources to teachers and students in Ireland, providing thus a forum for professional development of teachers and support of the students in the prostprimary level. One aspect of these resources is provided through the webpage: The platform provides material for the teachers and activities for the students for teaching and learning mathematics. In particular there are sections for problem solving. In these sections problems are presented that relate to everyday uses of mathematics as well as methodological approaches for their solution.

The EU COMPASS PROJECT
The project COMPASS (Common Problem Solving Strategies as Links between Mathematics and Science) was developed as a project funded by EU programmes. The goal of COMPASS is to provide teachers with interdisciplinary teaching materials which link mathematics and science. With the materials students can analyse and discuss problems relevant to society and their everyday lives. The whole project as well as the material produced can be found on the webpage: The Project aims to support teachers in developing problems that connect science and mathematics with each other and most crucially with the lives of the students.
