Plan with Radar

Ask Radar to plan your next lesson

Type “Plan the next Science 8 lesson.” Radar checks what the class did last and when it meets next, then shows you a full draft. Ask for changes in plain words. Nothing is saved until you say yes.

  1. 1 · It checks your plansLast lesson, unit, curriculum gaps and the next class dates — rotating days included.
  2. 2 · It asks only what it needsUsually just the focus, with a suggestion.
  3. 3 · You see the whole draftObjectives, timed activities, materials and homework.
  4. 4 · Change it by asking“Shorter warm-up.” “Move it to Monday.” Approve a week at once, and undo any change.

Radar can plan a lesson or a week on any plan. Planning whole units, and talking to Radar out loud, need Pro.
