Understanding Averages
From the British Broadcasting Corporation comes this BBC Skillwise tutorial on averages, means, medians, modes, and all sorts of other arithmetic that so many of us so easily forget. There's even a worksheet on "impossible Numbers." This delightful site provides multiple factsheets, quizzes, activities, and worksheets, including a "Shop Till You Drop" game designed to teach graphing skills.
