10Ticks is a montage of free mathematics lessons, worksheets, and games based on the UK's National Numeracy Strategy. One of the most popular attractions of the Web site is Pac Math, a fun game that allows children to practice basic arithmetic. Over 200 worksheets discuss topics in algebra, geometrical shapes and spaces, statistics, and more. Several more features are available after registration. For example, teachers can access free sample learning packs with suggested exercises to present in class, and students can keep track of their high scores in the various educational games. Because this is a UK-based site, registration can be somewhat confusing for foreigners.
