Room: Online
Time: Wednesday 6:30PM - 8:05PM
Grades: 7-8
Prerequisites: Math 6 or placement test
Material fee: $0.00

Description: In math 7 we will study more advanced topics than in math 6 in the areas of basic combinatorics and probability, quadratic equations and inequalities, coordinate geometry, and basic trigonometry. Studying online requires strong commitment - it also means that some of the learning will be done independently between the classes. Students should be equipped with a working web camera and a microphone. If possible, it is strongly recommended that the devices used for the meetings should have on-screen writing capabilities: e.g., an iPad, a tablet, or any touchscreen device as a cell phone. A basic stylus pen with a capacitive disc tip (any universal low-cost stylus) could be used to write on cell phone screens. Students will be expected to solve problems during class time individually and in groups, actively participate, and answer questions.
