Math 7 Part 2
LI.MAT.200712.2.HO
Course Length: 1 Semester
Has Textbook: Yes
Students will learn to solve two-step equations and will work with inequalities. This course will offer a solid foundation in mathematics by exploring topics that include geometric concepts and probability. The geometry discussion will include lines, rays, segments, angles, triangles, quadrilaterals, circles, irregular figures, prisms, and cylinders. With probability, students will work with experimental and theoretical probability, as well as permutations and combinations. Students will also work with percentages, a concept from Math 7 Part 1. Students can utilize videos, online games, and practice problems to help emphasize key concepts.
It is recommended that students successfully complete Math 7 Part 1 or equivalent course work before enrolling in this course.
