George spent most of the weekend watching NCIS, which made him paranoid that someone (or something!) was planning on breaking into his fort and stealing all of his pudding. In the most recent episode, DiNozzo said, “secure the perimeter,” so George decided to do the same. He remembered hearing about perimeter in a math lesson a couple of weeks ago so he opened up the textbook cabinet and got out a math textbook. He opened it up to the first page. No perimeter. He flipped through the book: polygons…fractions…absolute value… Ah hah! Perimeter!
George carefully read the instructions:
To find the perimeter, add up the lengths of all of the sides.
‘Hmmm,’ thought George. I have to find the length. He went to the kitchen drawer to cut a length of butcher string. ‘I wonder how long it needs to be,’ thought George. He spread his arms and cut the string as wide as he could. After he finished, he went back to the book. He needed to measure the string. Back he went to the cabinet to get a ruler. But the ruler was shorter than the string! Now what?
George sat at the table thinking for quite a while. He started to worry about getting the perimeter secure before dusk. “I must get back to work!” George decided he could measure the string by wrapping it around the ruler. The string measured one centimeter, wrapped around six times – that equals 6 centimetres!
‘Okay good,’ thought George, ‘now for the secure part.’ He reopened the textbook and read the next instruction:
If the shape is a square, multiply the length of one side by four.
George wondered if his perimeter was a square. He went to the mirror and looked at himself. He didn’t look square. “That mustn’t be it.” George went back to the kitchen. The sun was starting to set. ‘Oh no,’ George worried. He looked at the textbook again but there was nothing about securing perimeter there. Nothing! He was going to have to take matters into his own hands.
George decided that he needed to wrap his pudding up in string and use a secret knot to secure it. He got the butcher string back out and wrapped it around the pudding cups and tied it up with a bow. ‘DiNozzo would be so proud,’ George grinned and then he dozed off to sleep.
