Learning how to subtract fractions helps to start to build a great foundation and gain confidence as they move to more advanced math and science class. It will lead into multiplying and dividing fractions. Fractions are in everyday life: construction, recipes, landscaping, etc. In this lesson the student will learn about how to subtract fractions with unlike denominators and borrowing with fractions as they review adding fractions, equivalent fractions, improper fractions, mixed numbers, prime numbers, and LCM. At the end of the unit along with a test the students will be creating a 3-2-1 Bridge about adding fractions with unlike denominators.
