7th grade · Statistics & Probability
Design and use a simulation to generate frequencies for compound events. *For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?*
1 interactive, auto-graded activity for 7th grade students practising 7.SP.C.8c. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
This is a sub-standard of 7.SP.C.8.
Students build each tree diagram themselves, then use it to find the probability of compound events. Three real-world scenarios covering sample space, organized lists, and counting outcomes. Self-checking with instant feedback, so students catch a missing or repeated outcome as they go. Aligned to 7.SP.C.8a. About 20 minutes, no prep.
