1 MADISON PUBLIC SCHOOL DISTRICT GRADE 7 Robotics Cycle Authored by: Erik Lih Richard Newbery Reviewed by: Lee Nittel Director of Curriculum and Instruction Tom Paterson K12 Supervisor of Science and Technology Date: Fall 2012 Members of the Board of Education: Lisa Ellis, President Patrick Rowe, Vice-President David Arthur Kevin Blair Linda Gilbert Shade Grahling Thomas Haralampoudis James Novotny Superintendent: Dr. Michael Rossi Madison Public Schools 359 Woodland Road, Madison, NJ

2 I. OVERVIEW Robotics is a 2 marking period cycle course taught to all 7 th grade students at MJS. The course will introduce the field of robotics to students with an emphasis on engineering through efficient design and programming code. Students will be placed in small groups of 2-3 and will work through a variety of units that include an introduction to the NXT Robot, basic programming, electronic control, programming using variables and sensors, mechanics, design engineering, and the scientific process. The course will challenge students problem solving, teamwork, and time management skills. Integral to the module will be the interrelationship of science, math and technology in the modern digital world. Students will apply skills and knowledge from previous Tech Ed courses and begin to apply scientific and mathematical concepts learned throughout their educational careers to this real life, hands on experience. II. RATIONALE This class will serve as an introduction to a new world of technology. Robotics as an industry is growing in leaps and bounds. From personal robots to industrial robots, innovators are designing robots to take care of daily tasks, make production plants more efficient, and even solve Jeopardy questions. If our children are to be ready for the challenges of the 21 st Century, students must be equipped with the necessary skills to compete in this growing field. As explained in the LEGO curriculum, This course is designed to engage students in hands-on robotic investigations and experiments. Students will use creativity, logic, and problem-solving skills while learning and applying key STEM (Science Technology Engineering and Mathematics) concepts. This curriculum supports beginning robotics students, with a dual emphasis on programming and standards-based academic STEM concepts. ( n_to_mobile_robotics/1274) III. STUDENT OUTCOMES 2009 New Jersey Core Curriculum Content Standards Science By the end of GRADE 8, the following skills should be taught AND assessed: A.2 Use mathematical, physical, and computational tools to build conceptual-based models and to pose theories B.1 Design investigations and use scientific instrumentation to collect, analyze, and evaluate evidence as part of building and revising models and explanations B.2 Gather, evaluate, and represent evidence using scientific tools, technologies, and computational strategies C.2 Revise predictions or explanations on the basis of discovering new evidence, learning new information, or using models C.3 Generate new and productive questions to evaluate and refine core explanations D.1 Engage in multiple forms of discussion in order to process, make sense of, and learn from others ideas, observations, and experiences D.2 Engage in productive scientific discussion practices during conversations with peers, both faceto-face and virtually, in the context of scientific investigations and model-building.

3 5.1.8.D.3 Demonstrate how to safely use tools, instruments, and supplies E.1 Calculate the speed of an object when given distance and time. Common Core State Standards for Mathematics By the end of GRADE 7, the following skills should be taught AND assessed: Analyze proportional relationships and use them to solve real-world and mathematical problems. 7.RP.1. Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2 / 1/4 miles per hour, equivalently 2 miles per hour. 7.RP.2. Recognize and represent proportional relationships between quantities. Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn. Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate. 7.RP.3. Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Solve real-life and mathematical problems using numerical and algebraic expressions and equations. 7.EE.4. Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width? Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the

4 problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions. Draw construct, and describe geometrical figures and describe the relationships between them. 7.G.1. Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale. Solve real-life and mathematical problems involving angle measure, area, surface area, and volume. 7.G.4. Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle. 7.G.6. Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
