简单的可能性实验

进行简单的可能性实验——抛硬币、掷骰子、从袋子里摸彩色圆片——记录实验结果，并比较实验结果与理论预期结果。

Conduct simple probability experiments — flipping a coin, rolling a die, pulling coloured counters from a bag — record results, and compare experimental outcomes with expected theoretical outcomes

学习证据 / Evidence

• 抛硬币20次，用统计表记录正面和反面出现的次数，并说说对结果有什么发现。
• 掷骰子30次，比较每个数字出现的次数与原本预期的是否一致。
• 从袋子里摸彩色圆片，记录结果，并说明结果是否与预测相符。

• Flip a coin 20 times, record heads and tails in a tally chart, and describe what they notice about the results
• Roll a die 30 times and compare how often each number came up with what they expected
• Pull counters from a bag, record results, and explain whether the outcomes matched their prediction
