Idempotent

Proving trig identities is, for most Algebra2/Precalculus students, the most difficult problem type in the course. The difficulty arises from the multitude of possible steps to take. Years of experience have produced this ordered list of six actions. The way to use the list is to start at the top and go down the list until you hit an action that is possible. In almost all cases, if the action is possible, then it is the right one to take. This takes the guesswork out of the solution. Includ

This module is intended for approximately three weeks of instruction. It teaches basic probability from the perspective of set notation as required by the CCSS. Students will learn and practice set notation for union, intersection, and complement. All of the knowledge that students have built regarding sets is translated into equivalent concepts in probability. The final week includes a connection with geometry in which students calculate probability from their knowledge of length, area, and
