7th Grade Pre-Algebra
The 7th graders just completed a unit on probability. They learned about theoretical and experimental probability and how to use simulations. They found sample spaces of all possible outcomes of events, drew tree diagrams, used the counting principle, and found the probability of independent and dependent events. They reinforced the concepts covered in the classroom by working on additional problems on the School 21 web site. They finished the school year working on classifying angles and finding unknown angle measures.
