The topic of numerical expressions is crucial in mathematics as it bridges the gap between everyday language and mathematical notation. This collection of examples helps teach students how to interpret various verbal phrases and convert them into precise mathematical expressions. By presenting different ways to express subtraction, such as "take away," "minus," and "less," students learn to recognize and translate these terms accurately.

Providing multiple worked-out examples is essential for students to fully grasp the concept of numerical expressions. Each example reinforces the idea that different verbal cues can represent the same mathematical operation. This repetition helps students develop pattern recognition skills and build confidence in their ability to interpret and convert verbal statements into mathematical language.

Teacher Script: "Class, let's look at how we can turn words into math. When you hear 'Seven take away fourteen,' think about what operation we're doing. 'Take away' means we're subtracting, right? So, we write this as 7 - 14. Remember, the order matters in subtraction. We're taking 14 away from 7. Can you think of other words that mean subtraction?"
