900 factor lattice
I’ve been experimenting with the representations of factor lattices. Factor lattices are great for demonstrating a deep understanding of the multiplicative relationships between whole numbers.
Pick a number in the lattice above. If you travel anywhere in a northern or eastern direction you will find the multiples of your number, all the way to 900. If you travel in a southern or western direction you will find the factors of your number, all the way down to 1.
The real trick is designing them so that each row of numbers is increasing from the top left to the bottom right. It isn’t always easy to do.
