Step-by-step explanation:
The best example of an IEP Annual Goal for Scott concerning math problems that involve addition and subtraction is the one that sets a clear and measurable target for performance. An effective IEP goal should specify the type of problems, the level of difficulty, and a precise level of proficiency that the student is expected to achieve. Therefore, option 1, which states that "Scott will solve math problems that involve addition and subtraction of three- and four-digit numbers with 90% accuracy," is the best example because it is specific and includes a quantifiable objective.
When working with addition and subtraction, the basic principle is to line up the numbers according to their place values and perform calculations from right to left. Special attention should be paid to carrying numbers in addition and borrowing numbers in subtraction when dealing with whole numbers. Practicing with multi-step problems and using graphical methods for solving can also enhance a student's proficiency in mathematics.
