Math Vocabulary Inquiry

We needed to learn about terms for Data Handling so instead of teaching what it is and giving students a worksheet, I thought I would try using the same approach I had used for probability. I would give them a simple structure so they could learn the definitions but use their research skills to apply to their own data handling activities. I used a die roll ten times to provide an example of each (mode, mean, median and range) after which they found their own results. What was important is that it set up the opportunity to come to further questions rather than me letting them know in advance and when it wouldn't have held meaning or context to them. They simply asked when they were ready to learn. Questions arose such as, "What happens when you have two sets of numbers that occur the most?", "What happens when I get two numbers in the middle?" and "How do I divide a number that I don't know how to divide?"
