If their tray looks the same both times, they will have modeled the associative law. They could put the milk and vegetables on their tray first then the sandwich or they could start with the vegetables and sandwich then put on the milk. Students might think of some examples from their experience such as putting items on a tray at lunch. In this case, it doesn't matter if you add 9 + 5 first or 5 + 6 first, you will end up with the same result. An example of the associative law is: (9 + 5) + 6 = 9 + (5 + 6). It is best thought of in the context of order of operations as it requires that parentheses must be dealt with first. As with the commutative law, it applies to addition-only or multiplication-only problems. The order of the numbers stays the same in the associative law.

The associative law or associative property allows you to change the grouping of the operations in an arithmetic problem with two or more steps without changing the result. Most Popular Algebra Worksheets this Week And there is nothing like a set of co-ordinate axes to solve systems of linear equations. Algebra tiles are used by many teachers to help students understand a variety of algebra topics. Solving linear equations is much more fun with a two pan balance, some mystery bags and a bunch of jelly beans. Remember that by teaching students algebra, you are helping to create the future financial whizzes, engineers, and scientists that will solve all of our world's problems.ДЄlgebra is much more interesting when things are more real.
