Recording Transcript:
Me: Do we want to include the number 2? Class: No. Me: How do we show that we want values greater than 2? Class: Arrow to the right Student (raises hand to ask this question): Wouldn’t you start at 3? Me: So we don’t want to include 2, but we want to include numbers that are greater than 2. If we think of decimals, a decimal between 2 and 3 is like 2.5, right? Is that greater than 2? This is a really good question. We don’t want to include 2 but we want to include values between 2 and 3. The notation in math is that we circle the 2 and we want to include everything after the 2, so we use the arrow to show that. Student: So, start the line at 2? Me: Yeah, so start the line at the 2. |
