Adding Fractions with Unlike Denominators: 2/3 + 1/4

Adding Fractions with Unlike Denominators: 2/3 + 1/4

National Center on Intensive Intervention

This video demonstrates how to use the set model to add fractions with unlike denominators. The set model allows students to easily find like denominators and manipulate pieces of the fraction in order to perform computation; however, using the set model in this instance does require many steps and students need to remember that whole is represented by a set of chips (in this case, 12 chips). Beginners and students who struggle may benefit from a visual checklist to use while performing addition of fractions with unlike denominators using the set model.
