Patterns in whole numbers and area
Can you recognize patterns? In a seemingly unrelated collection of numbers or shapes or ideas, can you find relations?

Experiments in Mathematics
Mathematical experiments involve pen, paper, scissor, software and other tools.
Day 2 – Pattern in odd numbers
Sketch of the discussion:
 Can you write the first five odd numbers?
 Experiment with the sum of the first few odd numbers: add first two odd numbers, then add first three odd numbers, then add first four odd numbers extra to create a sequence. Do you see any pattern?
 Draw the sum of odd numbers. Notice that the sum of first n odd numbers is \( n \times n \)
