A scan of a printed warmup with the instructions to “pick three different numbers for x and then evaluate them for both expressions in the table. One expression is 2x - 3 and the other is 2x - 4 + 1. The student gets the same value for both because they are equivalent.
A prompt to “Count by 2’s” and shade in the squares on a 10 by 10 grid from 1 to 100. My kid has shaded in squares individually from 2,4, … 16, and then at 18 he starts shading the entire columns of numbers with 8 in the units digit.

Sarah Robertson, a former seventh-grade English teacher who's now a product manager for Khan Academy, walks Cooper through the process remarking that, when she was teaching, she had 100 students; if she spent 10 minutes on each of her students' first drafts, that was 17 hours of labor. "The burden that we place on teachers to give that specific, timely, actionable feedback is just so great that it's just not possible," she says. But perhaps the solution here isn't to have students write their paper for robots; perhaps teachers should not have 100 students.

Hey there! Let's wrap up today's lesson on percent increase and decrease. Imagine you found a $20 bill, and you decide to buy a video game that's on sale for a 20% discount. How would you calculate the final price you'd pay? Let's chat about it!
When I see a student staring at this problem with no work started, my first move would be to approach them gently and ask an open-ended question like: "Hey, what do you think about this problem? What’s the first thing that comes to mind when you read it?" This approach helps me gauge where they are in their understanding and gives them a chance to articulate their thoughts. If they seem stuck, I’d break it down further: "Can we start by figuring out what 10% of 15 is? Do you know how to find that?" This gives them a smaller, more approachable step to work on, while also keeping the conversation supportive and nonjudgmental.
