Objectives for this lesson:
1.
Given written fraction problems and word problems, students will correctly multiply fractions by whole numbers with at least 80% accuracy.
2.
During guided practice and real-life problem-solving activities, students will show confidence and persistence when solving fraction problems with 80% accuracy.
3.
Using fraction models, number lines, or written algorithms, students will demonstrate the steps for multiplying fractions by whole numbers by completing all steps correctly with 80% accuracy.
Important terms to remember
Of
The word “of” often means multiply in mathematics, especially in fraction problems.
When you see the word “of” in a math problem, it usually means you should multiply.
👉 Example:
½ of 8 means
½ × 8 = 4
