Description: Students will learn the importance of written communication skills and sequential thinking while trying to write a "computer" program on how to make a peanut butter and jelly sandwich. Teachers can use this activity as an introduction to writing computer programs.
Goal: To understand the importance of "meaning what you say," or "garbage in-garbage out," integrated with sequential thinking.
Objective: Students will write specific and sequential steps on how to make a peanut butter and jelly sandwich.
Teacher Materials:
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 input (read) their instructions to the computer (teacher). Then the teacher will "make" the programs, being sure to do exactly what the students say. For example, if a student says, "Take a piece of bread out of the bag," the teacher takes only a small "piece" out instead of a slice (which is what the student actually meant).
As a follow-up, students can edit their "computer programs" and have a peer read through them for clarity. As an extension, students can write directions for another "how-to-do" activity. Students can give their directions to another student to see if that student can follow the "program" without any problems.
Assessment: This activity is not one that can be "graded," but each student should complete the homework assignment and turn it in for the teacher to review.
Special Comments: 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! Also, I would like to give credit to Mrs. Holly Morrison, who was the initiator of this great lesson!
