This is a bundle of three Classwork and three aligned Homework Worksheets each for Identity, Communicative, and Associative Properties of Addition with answer keys. These are different than other worksheets on the web because each property is separated to work with a daily lesson. As a third grade teacher, I find that students have difficulty with traditional lessons that teach them in the same lesson. Students practice three types of representations for each property in class and at home: balance the equation, fill in the missing number, and identify the property by name. Classwork and homework are aligned so that students will receive repeated practice of the skill they were taught that day! Definitions of each term are at the top of each assignment as a scaffold. "Just enough" work to keep kids engaged without frustrating them with repetition in one sitting. Repetition as homework (or for morning work the next day) will help students master properties.
