By exploring different ways to express subtraction, such as using "from," students understand how language affects operations and number order.

The significance of multiple worked-out examples lies in reinforcing concepts for students. Each example highlights that different verbal cues can represent the same operation but may require careful attention to order. This repetition strengthens pattern recognition and boosts confidence in interpreting statements correctly.

Teacher Script: "Let's examine another way to express subtraction. When we say 'Four from one,' we're using 'from' as a cue for subtraction. But remember, it tells us that one comes first in our expression. So, we write this as 1 - 4. Can you think of other situations where 'from' might indicate subtraction?"
