Description

This example illustrates the conversion of the verbal expression "Thirteen into nineteen" into a numerical expression. The solution demonstrates that this can be written as 19 / 13 or 19 ÷ 13, showcasing two common ways to represent division in mathematics.

Numerical expressions, especially those involving division, are fundamental in mathematics. They serve as building blocks for more advanced algebraic concepts and problem-solving techniques. This collection of examples aids in teaching the topic by presenting various verbal phrases that indicate division and demonstrating how to translate them into mathematical notation.

Exposure to multiple worked-out examples is crucial for students to fully comprehend the concept of converting verbal expressions to numerical ones. Each example strengthens the pattern recognition skills needed to identify division language and translate it accurately. This repetition helps students build confidence in their ability to interpret and write mathematical expressions.

Teacher Script: "Let's look at this example together. Notice how the word 'into' is used to indicate division. In mathematics, 'into' often signals that we're dealing with division. When you encounter this word in a math problem, it's a clue that you'll be writing a division expression. Remember, we can express division using either a forward slash or the division symbol. Both 19 / 13 and 19 ÷ 13 are correct ways to write this numerically. As we continue with more examples, try to identify different words or phrases that might signal division in a problem."
