A prime number has two and only two factors.
Consecutive numbers are next to each other in the sequence of counting numbers
Thirty
days hath September,
April June and November.
All the rest have thirty-one
Excepting February alone,
Which has twenty-eight days clear,
But twenty-nine each Leap Year.
Many think that using the three lowest digits, i.e 1032 gives the smallest even four-digit number in which all the digits are different. But that's not the case!
Two to the tenth!
The day is a two digit prime number. The two digits are consecutive numbers.
The number of days in the month is a multiple of the number of letters in the month's name.
Add 10 times the sum of the first 3 multiples of 9 to the smallest 4-digit even number with all different digits.

Teacher, do your students have access to computers such as tablets, iPads or Laptops? This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments: Transum.org/go/?Start=July14 However it would be better to assign one of the student interactive activities below. |
