Programming Concepts

Grades 6-8

Concepts

Lesson Abstract

This is a lesson on the high level idea of programming concepts. It is not specific to a particular computer language, environment, or other such limitations. The goal is to teach the ideas behind programming, not to teach programming itself.

Standards Addressed

Objectives

Students should gain an understanding of some of the basic underlying concepts of programming.

Key Terms

Algorithm - a set of steps to achieve a goal
Parameter - a necessary resource for an algorithm
Loop - a set of steps repeated for a particular amount of time
Primitive - a pre-defined word that has meaning in a programming language
Initial Condition - a setting that you need before carrying out a particular instruction

Prerequisite Knowledge

Basic algebraic concepts (pre-algebra level) are helpful. Students need to be fluent in reading and writing of the language the course is taught in (for the purpopse of this lesson plan, we will assume English). Students need to have basic familiarity with the food item used (see below).

Teacher Preparation

The teacher should understand basic programming concepts before teaching this class. The teacher will require one assistant to act as the 'computer'; this assistant can be another teacher, an assistant teacher, college student, parent volunteer, etc. This person may need to be coached in the importance of following all of the instructions the students write literally.

Materials

Required Materials	Media	Equipment
1 jar of peanut butter 1 loaf of bread (pre-sliced, in a bag) 1 jar of jam or jelly 1 package of disposable knives 1 package of disposable plates Clean-up materials	None	One large whiteboard or chalkboard or three smaller whiteboards or chalkboards or equivalent erasable writing surface or surfaces

Safety

If any of the students are severely allergic to peanuts, substitute a cream cheese and jelly sandwich for a peanut butter and jelly sandwich. If you need to avoid the bread, use bumps on a log (celery with peanut butter and raisins). Beyond avoiding food allergy issues in the class, there are no particular safety concerns.

Presentation Outline

Introduction 10 minutes	Discuss the following topics: what is a computer, what is programming, and what is a robot. Explain the idea of programming a human 'robot' to make a peanut butter and jelly sandwich (or equivalent). Remind the students that a computer does exactly what you tell is to do. Assign students into teams for the exercise (minimum 3 per team, maximum 6; Minimum of 2 teams, maximum of 3).
Physical Modeling and Measurement 30 minutes	Explain the following to the groups: Each group will write a program for the robot to make a peanut butter and jelly sandwich, each robot will attempt to follow their groups' program in turn, groups are encouraged to observe and learn from other groups' attempts. Each group will be given a small chalkboard/whiteboard or a section of a larger one to work on their program. The group that says they have their program ready first will have theirs tested first.
Conclusion 10 minutes	Discuss the following subjects with the class: what was difficult about the activity, what are computers so literal, what did they learn from the activity, what would they like to know more about concerning the activity. After the discussion is finished give some real-world examples and give the students an idea of where to go if they want to learn more.
