Encourage students to explain their processes when converting from a mixed number to an improper fraction, and back again. Use this lesson on its own or as support to the lesson Single Strategy for Adding and Subtracting Mixed Numbers.
Students will be able to convert mixed numbers into improper fractions and back again.
Students will be able to explain how to convert between mixed numbers and improper fractions.
Conduct a "Which One Doesn't Belong?" conversation activity with four different fractional numbers written on the board, such as improper fractions, mixed numbers, and regular fractions (e.g., 1 2⁄3 subscript, 1⁄3, 5⁄3, 11⁄6). Ask students, "What do you notice about the numbers? What things are the same or different about the numbers?"
Discuss different categories or groups they can create (e.g., greater than one or less than one, all fractions or whole numbers and fractions, common denominators or unlike denominators, two terms are the same value (1 2⁄3 and 5⁄3), etc.)
Choose a volunteer to read the language objective: "I can explain how to convert between mixed numbers to improper fractions."
