TEACHING IDEAS FOR SIR CUMFERENCE...

	CONCEPT ATTAINMENT
	SIR CUMFERENCE AND THE FIRST ROUND TABLE
	"RADIUS" AND "DIAMETER"

PROCEDURE (PART ONE):

1. THE TEACHER TELLS THE STUDENTS THAT THEY WILL SEE SOME PICTURES AND THAT THE PICTURES ARE BEING USED TO SHOW A CERTAIN MATH TOPIC.
2. THE TEACHER USES THE CONCEPT ATTAINMENT INSTRUCTIONAL STRATEGY TO DEVELOP THE ATTRIBUTES OF CIRCUMFERENCE.
• THE TEACHER PLACES THREE "YES" PICTURES FROM THE "SAMPLE PHOTOS" LINK ON A T CHART LABELED "YES" AND "NO".
• THE STUDENTS ARE TOLD TO THINK ABOUT HOW THE YES EXAMPLES ARE THE SAME AND HOW THE NO EXAMPLES ARE DIFFERENT FROM THE YES EXAMPLES.
• STUDENTS ARE SHOWN ADDITIONAL PICTURES AND ARE ASKED TO USE "THUMBS UP" IF THEY BELIEVE THE EXAMPLES IS A "YES", "THUMBS DOWN" IF THEY THINK IT IS A "NO" AND "THUMBS SIDEWAYS" IF THEY ARE UNSURE.
• THE TEACHER ELICITS IDEAS FROM THE STUDENTS BY ASKING, "WHAT DO THE YES EXAMPLES HAVE IN COMMON? HOW ARE THEY DIFFERENT FROM THE NO EXAMPLES?"
• THE PROCEDURE CONTINUES UNTIL THE STUDENTS HAVE DETERMINED THAT THE YES EXAMPLES HAVE CIRCULAR OR CURVED EDGES, NO POINTS, ARE FLAT AND ARE MADE OF NEVER ENDING LINES.
• THE STUDENT'S SUGGESTIONS ARE CHARTED ON POSTER PAPER FOR FUTURE REFERENCE.
3. THE TEACHER EXPLAINS THAT TO MEASURE THE DISTANCE AROUND THE OUTER EDGE OF ITEMS WITH THESE ATTRIBUTES IS CALLED FINDING THE CIRCUMFERENCE.

EACH STUDENT NEEDS:

• A COPY OF THE STUDENT TASK
• TO BRING FROM HOME FIVE EXAMPLE ITEMS OR PHOTOS THAT WOULD ALLOW THEM TO FIND "CIRCUMFERENCE"
• A PIECE OF MODELING CLAY AND 30 CM LENGTH OF DENTAL FLOSS

THE TEACHER NEEDS:

• A COPY OF THE STORY BOOK SIR CUMFERENCE AND THE FIRST ROUND TABLE BY CINDY NEUSCHWANDER.
• A SET OF "SAMPLE PHOTOS" OR ITEMS AS EXAMPLES AND NON-EXAMPLES OF CIRCUMFERENCE
• A CYLINDER AND A CONE THAT MAY BE SLICED INTO A CROSS SECTION TO SHOW A PLANAR SURFACE
• A SET OF YES/NO GAME CARDS FOR EACH PAIR OF STUDENTS
