Knowledge and skills in most subject areas are cumulative.
Math is one of the most pronounced examples of the critical need for a continual progression of strong and steady skill development. If students have not mastered their times tables, then they will continue to struggle as they advance to more complex math subjects, and encounter more challenging standardized tests. Having to stop and think about basic math facts slows students down, frustrates them, and diminishes their performance. Students that struggle with pre-Algebra will continue to face difficulty as they encounter Algebra I and Algebra II. It is important that students with a weakness in math use the summer months to strengthen their math skills so that they do not fall further behind.
