Problem solving
1 There are 10 sheep inside a square-shaped fence Key Points
that has a diagonal distance of 15 m. Which of
the following statements is always true? First, divide the
space inside the
fence into nine equal
parts.
A. There are two sheep that are closer than 5 m.
B. There are two sheep that are 5 m apart.
C. There are two sheep that are farther than 5 m.
2 There are 20 cards numbered 1 to 20, and each Think about the
of the 20 students receives one card. If two cases that have 12
students have 12 as the difference between the as the difference
two numbers, they become taggers. At least how between the two
many students should be picked in order to find numbers and the
the two taggers? cases that do not
have 12 as the
difference between
the two numbers.
