Pentominoes

• Calder had received his first set of
  pentominoesDetermined, Calder moved the shapes
  into one combination after another, flipping and
  turning them. The biggest rectangle he had put
  together so far was six pieces.the Y had to
  slide into the U which had to fit next to the
  P..
• YUPhe had gotten his first twelve piecer!!
• (page 13)

Pentominoes

• Pentominoes are puzzle pieces made from exactly
  five squares. There are a total of 12 pieces,
  adding up to a total of 60 squares. You can
  arrange these pieces in four different
  rectangles. There are many solutions for most,
  but only two solutions for a 20 x 3 rectangle.
  You can flip and rotate pieces as much as you
  want.

Pentominoes

This is how they can be solved..
11
Speed , distance and time..

• Their (Cadler and Petras) houses were 3 blocks
  away from the U school and 3 houses away from
  each other. ..(page 10)
• The 5.38 south bound train went by Petras
  window exactly three seconds before it passed
  CadlersPetra had once calculated that it passed
  a house per second on Harper avenue. ..(page-18)

DISTANCE

• Distance is a numerical description of how far
  apart objects are at any given moment in time. In
  physics or everyday discussion, distance may
  refer to a physical length, a period of time, or
  an estimation based on other criteria
• The DISTANCE of Cadler and Petras houses from
  U.school is 3 blocks.
• Now, a city block is hardly an appropriate unit
  for distance.It varies from city to city. But on
  an average about 16 city blocks make a mile.
• So that makes the distance of Cadler and Petras
  houses from their chool to be about (3/16)th of a
  mile.

13
SPEED

• distance traveled per unit time
• a rate (usually rapid) at which something
  happens.
• Distance
  traveled
• Speed ------------------------------------
  --------------
• Time taken to cover
  that distance
• Example.
• If a train travels 200 miles in 2 hours. What is
  its speed?
• Total Distance 200 miles
• Total time 2hours
• Speed 200miles / 2hours 100miles / hour

14
PROBABILITY

• Calder stood up and reached into his pocket. He
  stirred the pentomino pieces around and pulled
  one out. V for Vermeer. One in twelve
  chance!!

15
PROBABILITY

• The chance that a given event will occur. It is
  an important area of mathematics study and a
  subject to which young children can be introduced
  through games of chance, such as coin tosses.
• If a fair coin were to be tossed, it has equal
  probability to give either heads or tails.
• Chance of it giving a head as output is
  equal to it giving tail.
• Therefore, probability of head or probability of
  tail is ½.

16
PROBABILITY

• Similarly, probability of getting the letter V
  out of 12 pieces in the pentominoe set is 1/12.
  Its the same for any of the 12 pieces.
• Probability of drawing a V and then drawing a
  P, without replacing any of the pieces that
  were drawn out
• ( probability of drawing a V )
  (probability of drawing a P)
• (1/12)(1/11)
• 1/256

17

• If two dice were thrown simultaneously , what is
  that probability that both give sixes?
• answer
• probability of getting a six in one dice
  1/6
• (for a six sided dice)
• therefore , probability of getting 2 sixes
• (1/6) (1/6)
• 1/36
