Subject: Re: Order of operations: group activities
There is an excellent software (DOS) program published by IBM several years ago called the Mathematics Exploration Toolkit. It had "defer" programs with worksheets that students completed as part of the package. The basic idea was to give students a list of numbers and operations, with the goal of creating an expression using only those numbers and symbols, with any "grouping" symbols they wanted to reach the goal number. If you don't have access to the software, you can create your own. For example, using the four numbers 3, 8, 3 and 9, and only the four basic operations and appropriate grouping, create an expression that will give a target number of -7/3 . Good luck.
