SIR CUMFERENCE AND THE FIRST
ROUND TABLE
"THE YES/NO GAME"
"RADIUS" AND "DIAMETER"
 
   

PROCEDURE (PART THREE):

  1. THE CHARACTERS OF THE STORY ARE REVISITED. USING THE DESCRIPTIONS OF "DIAMETER", "RADIUS" AND "CIRCUMFERENCE" FROM THE STORY, STUDENTS USE ANY METHOD THEY WISH TO ESTIMATE ALL THREE FOR EACH OF EXAMPLES THEY BROUGHT FROM HOME.
  2. EACH PAIR OF STUDENTS IS GIVEN A SET OF GAME CARDS TO USE AS LABELS. THEY CHOOSE TWO OF THE LABELS AND USE THEM TO SORT THE TEN EXAMPLES THEY HAVE BETWEEN THEM. THIS PRACTICE IS REPEATED SEVERAL TIMES TAKING TWO NEW LABELS EACH TIME.
    • STUDENTS MAY SORT USING A VENN DIAGRAM; TWO INTERSECTING HOOLA HOOPS PER PAIR WILL WORK WELL.
  3. STUDENTS PLAY "THE YES/NO GAME".
    • THEY USE THE GAME CARDS AND THEIR TEN EXAMPLES.
    • ONE STUDENT SECRETLY CHOOSES AND READS ONE OF THE GAME CARDS. THE LABEL REPRESENTS "YES" EXAMPLES.
    • THIS FIRST STUDENT THEN CHOOSES THOSE CIRCUMFERENCE EXAMPLES FROM HOME THAT MATCH IN THE YES GROUP. THOSE EXAMPLES THAT DO NOT MATCH THE CARD ARE REMOVED FROM THE GROUP.
    • THE SECOND STUDENT IS TO ANSWER "WHAT IS THE YES?" BY GUESS THE DESCRIPTOR ON THE REVERSED LABEL BASED ON THE EXAMPLES CHOSEN BY THE FIRST STUDENT.
    • ROLES ARE REVERSED AND A NEW LABEL IS CHOSEN FOR EACH NEW ROUND.
   
 

OBJECTIVES:

  • M-10 FIND THE CIRCUMFERENCE OF A CURVED OBJECT BY MEASURING
  • M-11 FIND THE DIAMETER OF A CIRCLE BY MEASURING
  • M-12 UNDERSTAND THE RELATIONSHIP BETWEEN THE RADIUS AND DIAMETER OF A CIRCLE

BIG QUESTIONS:

  • HOW CAN YOU ESTIMATE THE MEASUREMENTS OF YOUR OBJECTS? WHAT MATERIALS WILL YOU USE?
  • HOW DO YOU KNOW WHICH ITEMS ARE YES EXAMPLES AND WHICH ARE NO EXAMPLES?
  • HOW CAN THE STORY'S CHARACTERS HELP YOU TO REMEMBER WHAT THE TERMS DIAMETER, RADIUS AND CIRCUMFERENCE MEAN?

CLOSING:

  • STUDENTS USE A VARIETY OF MEASURING TOOLS TO FIND THE CIRCUMFERENCE, DIAMETER AND RADIUS OF THEIR OBJECTS FROM HOME (STRING, RULERS, MEASURING TAPES, ETC.).
  • A CHART MAY BE USED TO RECORD THEIR FINDINGS. "WHAT PATTERN DO YOU SEE BETWEEN THE DIAMETER AND RADIUS? WHAT RELATIONSHIP EXISTS BETWEEN THE DIAMETER AND THE CIRCUMFERENCE? THE RADIUS AND CIRCUMFERENCE?"
  • STUDENTS DRAW THEIR UNDERSTANDING OF THE THREE MEASUREMENT TERMS: CIRCUMFERENCE, DIAMETER AND RADIUS.
