EDUGAINS.CA
The AER library is a great resource to learn about assessment in mathematics. The five videos featured here are independent topics. The focus is on providing purposeful and planned feedback, and its role in the learning of mathematics. The videos talk about how to plan for purposeful feedback by questioning instead of writing paragraphs and explaining, as this encourages self assessment. In any learning environment, the ultimate goal should be making the learner as independent as possible.

THAT QUIZ
This website consists of some simple, but effective quizzes for elementary as well as secondary students. The quizzes are designed to provide the much needed practice. Setting up a classroom is very simple, and then you can design tests according to your requirements. Although the layout is pretty simple to navigate through, but the gray colour is far from inviting. It lacks the visual appeal, but seems effective.

Prodigy Math Games
This is a game with various arenas that the students play and verse their  opponents. They may win or lose a battle depending on the power they are using. The battle consists of Math questions that are based on the U.S. Standards and Canadian Curriculum.   It also has special EQAO programs designed for Canadian teacher. Planning lessons for practice is super easy as it takes only 2 minutes. It is free to set up your classroom on Prodigy. It will often prompt the players (students) to buy the membership, which is optional as it unlocks many items that they can win and use like other games. It is great for formative assessment, and might be useful for summative assessment. You can even differentiate as you can plan for small groups too.  Parents can also pick the levels at which their child is learning. The best part is that the children don't even realize that they are learning Math. Drawback: Does not work on Apple products yet due to Java issues, but will be available by September 2014.
