Simple Chance Experiments
简单随机实验
Description
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
Mastery Evidence
- 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
Assessment Prompt
Has your child ever done an experiment like flipping a coin or rolling a die lots of times, recorded the results in a tally chart, and noticed any patterns in what came up?
