Domino Totals

The following three dominoes give you a total of 100 if you add them together:

Can you think of another way to make 100 with three dominoes?

How did you choose your dominoes?

Investigate other ways of making exactly a 100 with three dominoes.

If you are not allowed any doubles or blanks in your dominoes then how many sets of 3 dominoes that equal 100 are there? How do you know that you have them all? Could you convince a friend?		If you only had 2 dominoes how many ways would there be? Would there be more or less? How many different combinations will there be?

With three different dominoes in a set what is the largest and smallest total that you can make?		If you had a set of 1 to 9 dominoes would you have double the number of combinations for either sets of 2 or 3 dominoes that equal 100?

Key Stage 1:

In a standard pack of dominoes

are there more odd totals, more even totals or the same amount of odd and even totals when you add the two sides? Investigate.

If you added the spots on both sides of three dominoes

how many different ways could you make a total of 20?
