Glen Ridge Public Schools – Computer Science Curriculum

Course Title: Introduction to Robotics Subject: Mathematics/Computer Science Grade Level: 8th grade Duration: 18 weeks (3 days per week) Prerequisite: None Elective or Required: Elective Mathematics Mission Statement

Since Mathematical and Computational thinking are an integral part of our lives and 21

st Century

learning, students must be actively involved in their mathematics education with problem solving being an essential part of the curriculum. The mathematics and computer science curricula will emphasize thinking skills through a balance of computation, intuition, common sense, logic, analysis and technology. Students will be engaged and challenged in a developmentally appropriate, student-centered learning environment. Students will communicate mathematical ideas effectively and apply those ideas by using manipulatives, computational skills, mathematical models and technology in order to solve practical problems. To achieve these goals, students will be taught a standards-based curriculum that is aligned with the National Common Core Standards in Mathematics and the New Jersey Core Curriculum Content Standards in Technology and 21

st Century Life and Careers.

Course Description:

Introduction to Robotics is an 8

th grade cycle course. Students will be introduced to Robotics

using the Lego® MindStorms® NXT system. The course will use the Carnegie Mellon Robotics Academy NXT Video Trainer 2.0. Working as part of a team, students will build and program a Lego NXT Robot. Using basic robotics concepts and the NXT programming environment, students will instruct the robot to move, turn, sense light, sound, touch and other objects in its path. Students will program their robot to navigate obstacle course challenges.
