Numerical Expressions

Description

This example illustrates how to convert the statement "Eight times negative eleven" into a numerical expression. The word "times" clearly indicates multiplication, and the presence of a negative number introduces the concept of multiplying positive and negative integers. The resulting expression is 8 * (-11).

Understanding numerical expressions is fundamental in mathematics as it allows students to translate verbal descriptions into mathematical language. This collection of examples helps teach the topic by presenting various scenarios where multiplication is expressed in everyday language, including cases involving negative numbers. Students learn to recognize key phrases and translate them into mathematical symbols, while also grasping the rules for multiplying positive and negative numbers.

Providing multiple worked-out examples is crucial for students to fully comprehend the concept of numerical expressions, especially when dealing with positive and negative numbers. Each example reinforces the underlying principles while introducing slight variations, helping students develop a flexible understanding of how language can represent mathematical operations. This approach aids in building pattern recognition skills and enhances overall mathematical fluency.

Teacher Script: "Notice in this example how we handle the negative number. When you see the word 'times,' it's a clear signal for multiplication. But be careful with the negative sign - it stays with its number in the expression. Can you think of a real-world scenario where you might multiply a positive number by a negative number?"
