English: Step 1: Just LinesBefore you play the video, ask students to quietly think about what they are going to see as they watch.“What do you notice, what do you wonder?”Play it again before they share. Play a third time! Ask them – “Share with your partner/group what you notice and wonder.”After they’ve discussed with partner/group, have them share with the whole class.Accept all their notice/wonder comments.Make a chart on the board with three columns, labeled “Too Low”/”Just right”/”Too High”“In your pair/group, decide how many lines there are? What’s an answer that’s too low? Too high?Record answers suggested by each pair/group.“What’s a ‘just right’ estimate based on these too low/too high boundaries?” Record their estimates, allowing students to adjust their estimate boundaries or estimate as they entertain the input from other groups.
