When teaching students to add decimals, I wind up reminding students to “line up the decimal points.” This makes sense to some students while others follow the rule without understanding. How can we teach adding decimals to develop understanding and skill? Here’s a possible suggestion: Give the correct answer up front. ]]>http://www.marilynburnsmathblog.com/teaching-adding-decimals-what-if-you-gave-the-answer-first/feed/13One Lesson, Two Pedagogical Mistakes

On November 3, 2017, I saw this image in a Tweet posted by @MarkChubb3. The image stuck with me for several days.

I made arrangements to “borrow” three fifth-grade classes and made plans to teach the same lesson in each class.
