Numerical Expressions

Description

This example demonstrates how to convert the verbal expression "Fourteen goes into seven" into a numerical expression. The solution shows that this can be written as 7 / 14 or 7 ÷ 14, illustrating the two common notations for division in mathematics.

Understanding numerical expressions, particularly those involving division, is crucial in mathematics. It forms the foundation for more complex algebraic operations and problem-solving. This collection of examples helps teach the topic by presenting various verbal phrases that indicate division and showing how to translate them into mathematical notation.

Seeing multiple worked-out examples is essential for students to fully grasp the concept of converting verbal expressions to numerical ones. Each example reinforces the pattern recognition needed to identify division language and translate it accurately. This repetition helps students develop confidence in their ability to interpret and write mathematical expressions.

Teacher Script: "Let's examine this example together. Notice the phrase 'goes into' - this is another way of expressing division. When you see this phrase, you know you'll be writing a division expression. However, be careful with the order! 'Fourteen goes into seven' means seven divided by fourteen, not the other way around. Remember, we can write division using either a forward slash or the division symbol. Both 7 / 14 and 7 ÷ 14 are correct ways to express this numerically. As we go through more examples, try to spot the different ways division might be described in words, and pay attention to the order of the numbers."
