The following Decimal Multiplication versus Whole Number Multiplication Rounding Organizers 1-3 with answer keys challenges students on the following math common core concept: 5.NBT.A.4: Use place value understanding to round decimals in any place. These organizers provide students an opportunity to solve decimal multiplication problems, round the decimals, and then compare the products using the <, >, and = symbols. For the most part, students will see the products are quite close; however, as the complexity of the decimals increases, so does the disparity in the products (although they are still quite close for most of the problems). Each organizer also includes a challenging extension for the students to attempt. Enjoy!
