Daniel wrote to say:

We did some caterpillars, and in all the different ones we did each medium square (made up of four squares inside our big square) added up to an even number, and all the rows and all the columns did too.
All the 9-square squares in our big square added up to odd numbers.  We think that is because there was an odd number of squares in those squares, and because of the caterpillars being odd then even then odd then even.

Thank you for these contributions.
