Numeracy Update – February 2019


Four Fours

Here’s the challenge:  How many numbers can you generate using only four fours and the operations below?

        Addition              Subtraction

   Multiplication      Division

         Parenthesis        Exponents

  Factorials            etc…

Here is how it works:   4x4 – 4x4 = 0

                                    (4 + 4)/(4 + 4) = 1

Can you generate a number sentence resulting in all the numbers to 20? 100?

Playing around with numbers and seeing what happens is a big part of the puzzle.

Put the numbers 1 – 20 on your fridge.  Get creative and make it a family challenge!
