This 2 page (can be printed back-to-back) PDF is helpful in explaining to parents why the traditional addition algorithm of "stacking" is not always the best, nor the most efficient, method available to children. This is great Back To School Night information, and may help parents understand your classroom's math program from the very start of the school year. It illustrates some of the strategies that they will see their children learning in today's classroom. This PDF contains examples of three addition strategies that help students with mental math - 1) adding by place value, 2) adding one number in parts, and 3) rounding then adjusting one's answer. The emphasis is on creating flexible thinking patterns for math computation.
