Student
errors can be useful tools for teachers to determine how to tailor their
curriculum and instruction to meet the needs of their students. Student errors
reveal where previous instruction failed and where further instruction is
needed for students to grasp important mathematical concepts. It is often the
case that students understand the general premise of how to calculate particular
problems but continuously make the same slight errors that cause them to get
the wrong answers. For example, a student can multiply numbers correctly but
position the products in the wrong place values and therefore get the wrong
answers. Another example occurred when a student divides correctly but is
dividing the wrong numbers and calculates the answer incorrectly. Teachers need
to practice locating errors from student example problems and determining the necessary
skills that need to be retaught in order to effectively aid students in
learning mathematical skills.
