Our Interpreting Multiplication Scaling lesson plan explores the difference between multiplying a whole number by a fraction and multiplying a whole number by a number greater than one. The lesson demonstrates with visual aides how numbers change as they are multiplied. Students are asked to decide which number is bigger without multiplying using strategies learned in this lesson. Students are also asked to complete practice problems on their own in order to demonstrate their understanding of the lesson.
At the end of the lesson, students will be able to predict the products of whole numbers and fractions and to determine if the product is greater than or less than the original number.
