9th Grade – Geometry

God created humans with a rational and inquiring mind. He blessed them with the ability to count, tell time and make change. In Mathematics we will explore and develop this God given gift systematically. As the Bible says “precept upon precept, line upon line …” (Isaiah 28:10), students will systematically build up their knowledge of Mathematics. As they learn the different disciplines of Mathematics students will recognize the logic and order God imbued in the world and by implication that God is a god of logic and order. They will develop a greater understanding and appreciation of God through their study of mathematics.

Course Objective
Students will recognize that our ability to learn about our world rests on the fact that we are created by a rational Creator; they will also see that as believers it is important to think logically and reason well.  They will also reflect on ways to use math to serve others, not just to benefit themselves (ESLR: RC).  Students will acquire and demonstrate knowledge of concepts, definitions, properties, and applications of the course contents listed below as well as develop the computational skills and strategies needed to solve problems (ESLR: ET, NLL). Technology is stressed and integrated in lessons and exercises throughout the course in order to improve student’s overall understanding (ESLR: SCW). Some hands-on activities using manipulatives will also be included to better understand two and three-dimensional concepts (ESLR: NLL).  Throughout the course, students are given opportunities to exercise communication skills – in talking, listening, writing, representing, modeling, and reading (ESLR: DC). Students will develop critical thinking, communications skills, and decision-making skills by connecting concepts to practical applications (ESLR: ET, DC, SCW).
