Peanut Butter and Jelly Programming Computer, level: Middle Posted Tue Mar 6 07:33:12 PST 2001 by Deb Sweeney (sween4@yahoo.com). Tamaqua Area Middle School, Tamaqua, PA USA Materials Required: Paper, pencil, peanut butter, jelly, bread, butter knife Activity Time: one class period Concepts Taught: Written communication skills and sequential thinking with writing computer programs. Goal: To understand the importance of "meaning what you say", or "garbage in-garbage out", integrated with sequential thinking. "Garbage in-garbage out"-means that if a programmer states inaccurate or incorrect steps (garbage), the computer will output garbage as well. Objective: Students will write specific and sequential steps on how to make a peanut butter and jelly sandwich. Procedure: Students will write a very detailed and step-by-step paragraph on how to make a peanut butter and jelly sandwich for homework. The next day, the students will then input (read) their instructions to the computer (teacher). The teacher will then "make" the programs, being sure to do exactly what the students said. For example, if they say, "Take a piece of bread out of the bag," the teacher would only take a small "piece" out instead of a slice (which is what they actually meant). Assessment: I use this as an introduction to writing computer programs. I do not use it as a grade, except if the student did not do the assignment. Students have a great time with this assignment because they can actually "see" their errors, or bugs, in their programs when their sandwiches are only 1" square! *Special acknowledgement to Mrs. Holly Morrison, who was the initiator of this great lesson!       June: The 30 Days of Teachers.Net (Introduction) 1 The Gazette 2 The Mailrings 3 Harry Wong 4 Lesson Bank 5 Tech Center 6 Teacher Classifieds 7 State Teachers.Net 8 Live Chat & Meetings 9 Teacher Printables 10 Project Center 11 Chatboard Network 12 Share Teachers.Net 13 Your Feedback 14 Interest Groups 15 Administrators.Net 16 Chat Center 17 Streaming Teacher Video 18 Tutoring Center 19 Academic Grants 20 Teachers.Net Bookshelf 21 Chatboard Tips 22 Grade Levels 23 Staffroom Flyer 24 Teachers.Net Archives 25 Hot Topics 26 Language Arts 27 Subject Areas 28 Quick Links 29 Meet Teachers.Net 30 Summer Job Fair
