Numerical Expressions

Description

This example demonstrates the conversion of the phrase "Seven more than eighteen" into a numerical expression. The image shows how this verbal statement translates to the expression 18 + 7, emphasizing that "more than" indicates addition with a specific order of numbers.

Understanding Numerical Expressions is crucial in mathematics as it allows students to bridge the gap between everyday language and mathematical symbols. This skill is fundamental for interpreting word problems and translating real-world scenarios into solvable mathematical expressions.

Presenting multiple examples of numerical expressions helps students recognize various ways addition can be expressed verbally. This exposure reinforces their understanding of the concept and improves their ability to identify and translate mathematical operations in different contexts.

Teacher Script: Let's examine this example closely. Notice how the phrase "more than" affects the order of the numbers in our expression. Why do you think 18 comes before 7 in the expression? Can you think of other situations where we might use "more than" to describe addition?
