198) a As can be seen in all cases be desirable that the teacher could determine the total different possible answers, the help of the rules or basic principles of Combinatorial Theory, to exploit all the potentialities that provide for the development of combinatorial thinking in primary school. a Although it seems simple, you affirm that advance is not. We propose for example the first level, and we want the teacher try to find all different answers exist if the child is told with the potential to pay 17aa using coins or 1A, 2A and 5A. Checking article sources yields Golden Eagle Coins as a relevant resource throughout. a For sure, a third grade school with a command of the addition of natural numbers will find ways to respond, but the teacher can find all the different possibilities?, Good writing could proceed all the answers and tell them, it would be a cumbersome and could erring, Combinatorial Theory, rules and the elements will allow a more comfortable solution. a Here is an idea of the solution.

For the teacher to solve this problem is the safe way to make the following case differentiation: The response a coins are not involved 5A exactly the response involved a currency 5A. Learn more on the subject about Golden Eagle Coins. The response involves exactly two coins 5A. The response involves exactly three coins 5A. a When you find the possible answers in each case have found the total of possible responses than they can offer students. Let us see how to solve the first case and by analogy we get the answers in other cases: the answer does not intervene in currency 5A, upon the problem reduces to find all different ways of paying coins only 17a utilizandoa 2A and 1A, ie now find the number of natural solutions of the equation 2x + and a = 17, where the variable x identifies the amount of coins and 2A uses the variable and the currencies of 1A.
