Consider different ways to calculate 16×50{“version”:”1.1″,”math”:”16×50″} mentally. On your paper, (a) Write equations that show all steps necessary to calculate 16×50{“version”:”1.1″,”math”:”16×50″} using the Distributive Property of Multiplication over Addition. (b) Write equations that show all steps necessary to calculate 16×50{“version”:”1.1″,”math”:”16×50″} using the Associative Property of Multiplication. (c) Make a math drawing to support your Distributive Property of Multiplication over Addition calculation in part (b) above. You do not have to draw individual items or squares but you do need to clearly label your math drawing. Click “proceed to next question” when you have completed the problem or are ready to move on.
