When students learn how to multiply whole numbers, they develop the assumption that all multiplication expressions will result in a greater product. That is simply not the case when it comes to multiplying fractions. These guided notes will give your students the opportunity to see when fraction multiplication results in a product that is greater than, less than, or equal to the original factors. Students will develop their own conjectures and prove their thinking by multiplying. These two pages of notes can be spread out over the course of two lessons and include...
fractions x fractions
fractions x one
fractions x whole numbers or mixed numbers
mixed numbers x fractions
mixed numbers x one
mixed numbers x whole numbers or mixed numbers
Students will need to be familiar with multiplying fractions, whole numbers, and mixed numbers before conducting this lesson.
