@AttainRen Recently, Primary 7 have been learning about number patterns and sequences…we can now tell you all about square numbers, square roots, Fibonacci and Pascal!

We also studied triangular numbers and worked with a partner to represent the first ten triangular numbers before sharing our strategy with the rest of the class.

Things then got a bit trickier when we then tried to find the 20th triangular number!

We quickly realised that the previous strategies would take us a long time and so tried to look for a different way of doing this…after learning about Carl Gauss and how he was able to quickly calculate the 100th triangular number, things became much clearer!
