This site has numerous interactive activities, games, mind benders, puzzles, and lessons for students of all ages. Included are games on arithmetic, money, telling time, probability, and algebra. In Number Monster, students choose an operation: addition, subtraction, multiplication, or division and a level of difficulty ranging from easy to monster. A problem is shown and the student types in the answer. Lessons on tessellations, what congruent means, interior angles of regular polygons, and fractions can be found. Links to science and other math sites, coloring books that can be printed out, thinking games, and games for preschoolers can also be found. Included are links for teachers, parents, and students 13 and older.
