Description

This example focuses on converting the statement "Eleven multiplied by the quantity sixteen plus four" into a numerical expression. The solution demonstrates that this can be written as 11 * ( 16 + 4 ). This example reinforces the use of grouping symbols to represent the phrase "the quantity" in mathematical notation.

Understanding numerical expressions is crucial for students as they progress in mathematics. These examples help students develop the ability to translate between verbal and symbolic representations of mathematical ideas. By practicing with various phrasings, students become more adept at recognizing mathematical operations and structures in word problems.

Exposure to multiple examples is vital for students to internalize the patterns and rules of converting verbal statements to numerical expressions. Each new example provides an opportunity for students to apply their understanding, reinforcing the concept and helping them identify similarities and differences between various expressions.

Teacher Script: "Now, let's look at this example. We see 'Eleven multiplied by,' which tells us we're multiplying by 11. The phrase 'the quantity' signals us to group what follows. So, we put 16 plus 4 in parentheses. Our final expression is 11 * ( 16 + 4 ). Notice how the parentheses ensure we add 16 and 4 before multiplying by 11."
