Finally, as a whole class activity, they gather the circle graphs from all the groups, and rearrange the sectors to make as many solid color circles as they can. They discuss the results. Determine the probability of a simple event, assuming equally likely outcomes. Children roll a die ten times and record the number of times each number comes up. They combine their tallies and discuss the class results.
Children predict how often heads and tales come up when a coin is tossed.
They toss a coin ten times and tally the number of heads and tails. They combine their tallies and compare their class results with their predictions. Make predictions that are based on intuitive, experimental, and theoretical probabilities. Second graders are presented with a bag in which they are told are marbles of two different colors, twice as many of one color as the other. They are asked to guess the probability for drawing each color if a single marble is drawn.
