Provide "acknowledged body of knowledge" related to the concept. Emphasize the most significant aspects of the concept in an organized, organic manner. Present information sequentially so students see continuity. Draw attention to important, discrete details; don't swamp students with myriad facts.

Lecture with demonstration; binary system kinesthetic activity

Objective: To explain how computers use the binary system. To explain how and why programmers use the hexidecimal system. To explain how to convert from decimal to binary to hexidecimal.

Activity: 1) Tape eight signs to the wall that read "1, 2, 4, 8, etc." Have eight students wear signs that read "0" and "1" and stand under the signs on the wall. The teacher then physically places the eight students into a line and by turning their cards over, constructs binary numbers and explains how to translate those binary numbers into decimal numbers. The teacher can then illustrate how each group of four students is a "nibble," while all eight students represent a "byte." The teacher then uses each nibble to explain how binary can be converted to hexidecimal. 2) Teacher does conventional lecturing and diagramming at the board for emphasis. 3) Students read textbook.

Assessment: Teacher checking for understanding; quality of student questions and involvement in interactive lecture/discussion.
