The following example shows that a unified approach to problem solving based on basic mathematical concepts is valuable across the curriculum. Implementing a unified approach to problem solving in early grades serves to lay the ground work for more efficient learning in all subjects which use mathematical methods in problem solving.

The basic element of a problem solution is Request-Response-Result. This structure is shown below. It is from this that problem solutions are generated. The linear nature of problem solutions assures that recursive use of Request-Response-Result in the transformation process will lead from the initial premise to the answer to the specific question asked.

The problem solution was developed using SureMath.
