The Correct Order ****


You need to place the numbers in the correct order according to the clues given.  For each problem the numbers may not be in the place that relates to their value.  For example, 1 cannot be in the first position, 2 cannot be in the second place, 3 cannot be in the third place…and so on.


 a) Using 1  2  3  and  4:

  • The four is directly to the right of the two.
  • The first number and the last number add up to five.

b) Using 1  2  3  and  4:

  • The even numbers are not next to each other.
  • The 1 is directly to the right of the 3.

c) Using 1  2  3  4  and  5:

  • The first and fifth cards add to 6.
  • The third and fourth cards add to 6.
  • The second and third cards add to 4.

Helpful tip:  Write the numbers on little pieces of paper (or use playing cards) so that you can move them around easily as you try out your ideas.
