### Factor domino game

Look at this NEAT visual representation of the counting numbers:

The first activity you can give to your students or children is to figure out HOW it is made! What is it based on? The last number on this chart is 49. Can you figure out how to make the next number, 50?

Malke shared a cool factor domino game with her readers. We played it, too. Here's one of our games:

(We had a few cards that were not the same size; just ignore that.)

Basically, you may put a card next to another if they share a factor. Using these visual dominoes makes children easily learn about factors and factorization. Please visit Malke's blog to read the rules and see more details.

Here are a few other things you can do with these cards:

1) Organize them in some way. For example, you could find all multiples of 5, all multiples of 4, or all primes.

2) Pick up two cards randomly and tell their least common multiple (LCM). This can easily be done if you notice their factorization from the visual (the LCM has to include all the factors from both numbers).

As to finding the greatest common factor, you can do that too, but I feel it would work better with bigger numbers.
