Lessons
Data Detectives
How fast are our reflexes? Which graph is telling the truth? Do taller people really have bigger hands? Three lessons where students collect their own measurements and find out what numbers can and can't tell you.
Is It Fair? Chance and Probability
Is a six harder to roll? Which bag gives the best chance of a red? Why does horse 7 always win? Can you design a fair game? Four lessons with dice, coins, counters and spinners where students test their hunches and find out what chance really does.
