Understanding numerical expressions, particularly those involving multiplication, is a crucial skill in mathematics. This collection of examples helps students recognize various verbal representations of multiplication and translate them into mathematical notation. By exploring different ways to express multiplication in everyday language, students develop a more comprehensive understanding of the concept and improve their ability to interpret and create mathematical expressions.

Presenting multiple examples is essential for students to fully grasp this concept. Each example showcases a unique verbal representation of multiplication, allowing students to identify patterns and similarities across different phrasings. This repetition and variety reinforce the concept, enabling students to more easily recognize and translate multiplication expressions in diverse contexts.

Teacher Script: "Let's look at another common way to express multiplication. When we say 'Fourteen multiplied by eighteen,' we're using a more formal phrase to indicate multiplication. The term 'multiplied by' is directly translated to the multiplication symbol in math. So 'Fourteen multiplied by eighteen' becomes 14 * 18 in mathematical notation. Can you think of situations where you might use 'multiplied by' instead of 'times'? How would those situations look as math expressions?"
