Problem solving approach

Front

This is a process that is the primary goal of math instruction. Students preform this by using a real world problem that requires them to work through steps to determine the answer. Time should be allowed for student to try out many solutions. discussion should take place about the students thinking. 1) Read and understand the problem (restate) 2)Make a plan (strategy ) 3)carry out the plan (work) 4) Look back to assure that it makes sense (reflect)
