This 30-minute coordinate lesson pairs a complete 0–4 grid with voice, approved text, and delayed paper routes. The group model starts at (1,1), moves right two and up one, and ends at (3,2). The individual task starts at (2,1), moves left one and up two, and ends at (1,3). The HTML activity checks the individual coordinates and keeps the selected participation route separate from the answer.
Supply the grid before the session
Declare that x increases rightward and y increases upward. Give learners the grid and both written prompts in advance, whether on paper or through an approved channel. No required video or pre-class assessment is part of this example.
For the group model, right two changes x from 1 to 3 while y stays 1. Up one then changes y from 1 to 2. Write the intermediate point (3,1) as well as the endpoint (3,2). That intermediate point makes the two operations available for discussion.
Cornell's online active-learning guidance emphasizes clear written instructions and expected outputs. Apply that principle to the task sheet: a learner should know what to return even if the spoken explanation was interrupted.
Plan the live minutes separately
Use five minutes for access and instructions, five for modeling, eight for paired tracing, six for comparison, four for individual transfer, and two for checking response routes. The sum is 5 + 5 + 8 + 6 + 4 + 2 = 30 minutes.
Within the pair, the tracer follows the operations and the reporter states or writes the route and reason. Their shared answer is group work. It should not replace the independent response collected during the transfer phase.
The proposed delayed response window is 24 hours. Confirm its actual start, end, time zone, recipient, and return channel before communicating a deadline. That window is separate from the live session; it does not turn the teaching allocation into 24 hours and 30 minutes.
Ask for the route as well as the endpoint
For the independent task, begin at (2,1). Moving left one gives (1,1). Moving up two then gives (1,3). Learners enter the intermediate and final coordinates and write what changed on each axis.
An endpoint of (1,0) invites a question about which direction increases y. A correct endpoint with an empty explanation invites the learner to describe the two operations. The local checker compares coordinates; the teacher reads the explanation and decides the next instructional step.
The HTML view includes the complete coordinate grid and the group model, while leaving the individual answer fields blank. It can therefore serve as a practice sheet without presenting the teacher's transfer answer as an actual learner response.
Keep route status out of correctness
Choose Live voice, Approved text, or Delayed paper to see the same evidence requirement: intermediate point, endpoint, operations, and explanation. The delayed route uses the already supplied prompt. It does not ask learners to reconstruct a lost video.
A missing response is a follow-up question. After a connection failure, record the route and access note separately from any answer review. The local route selector does not create a receipt or submit an assignment, and its temporary entries disappear on reload.
Copy this prompt
Create a complete offline US-English HTML coordinate lesson and participation plan. Use a calm teaching-sheet layout with a readable original 0..4 coordinate grid, x increasing right and y increasing upward. All text must be at least 16px; fit 360px with generous controls and no remote dependencies.
The group model starts at (1,1), moves two columns right to (3,1), then one row up to (3,2). Show those operations as a worked reference. Roles are tracer and reporter; the pair produces one shared answer.
Live session phases are 5 minutes access/instructions, 5 model, 8 paired trace, 6 compare, 4 individual transfer, 2 route check, totaling 30. Display the full sequence.
Individual transfer starts at (2,1), moves left one, then up two. Provide blank labeled intermediate x/y and endpoint x/y inputs plus an explanation field. On a type=button Check click, distinguish blank, invalid coordinates outside integer 0..4, incorrect intermediate point, incorrect endpoint, and matching coordinates. Correct trace is (1,1) then (1,3). Explanations require teacher discussion rather than automatic grading. Edits clear stale feedback.
Provide Live voice, Approved text, and Delayed paper buttons. Each route requires the same individual evidence and does not create a submission receipt. Delayed paper uses the existing sheet; its proposed 24-hour response window has unconfirmed actual dates, time zone, recipient, and return channel. Keep this separate from live minutes.
Include Reset. No student collection, saved responses, platform integration, invented deadlines, absence diagnosis, or sending. Keep native classroom records authoritative. Return complete self-contained HTML with explicit selectors and keyboard-accessible controls.
Before class, choose the approved return channel and prepare the paper sheet. Preview the grid and route instructions together in NOS if an HTML teaching copy helps your preparation. Keep actual learner work, receipts, and feedback in the classroom's required records, then use the same coordinate explanation regardless of how each learner returns it.
