standard_description: Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.
problem_activity: Task
Materials:
Sheets of paper for each student that are folded in half with the words "Heavier" and "Lighter" written at the top of each side.
[IMG]
A box of large blocks.
A box of different objects with different weights to compare with a block from the first box. Some should be lighter than a single block and some should be heavier. The weight differences should be fairly pronounced.
Action:
The students begin by choosing a block that they will use to compare with other objects.
Students will then choose an item from the second box and compare its weight to their block. They then draw a picture of it under "Heavier" or "Lighter" depending which applies. They continue to choose objects from the box to measure against their block until they have two or three drawings on each side of their sheet.
