How this resource helps
Students compare two fictional robot-cart trials, plot distance-time graphs, interpret pauses and changing interval speeds, and justify which cart meets a delivery deadline and required pause. Includes three analysis stations, an independent exit ticket, complete teacher guidance, and a 12-point claim-evidence-reasoning rubric. Teaching sequence: two 55-minute lessons. Print core student pages 5-15; use optional support and extension pages 16-17 as needed. Keep teacher answer pages 18-22 separate from student copies. The optional extension adds 10-15 minutes. Pacing is an estimate; the resource has not been classroom-piloted. Differentiation: multilingual vocabulary and sentence frames, EC chunking and calculation supports, accommodations for teachers to apply according to individual 504 plans, and an advanced route-design challenge. Selectable text; labeled graph axes; data available as tables/coordinate text; line styles and marker shapes supplement color. Not a fully tagged or accessibility-certified PDF. Focused practice for PS.7.1.4, not a complete curriculum, official assessment, mastery guarantee or EOG endorsement. All data fictional. PDF only; no editable slides or physical lab materials. The free sample has 6 pages: a sample introduction, mission/warm-up, graph toolkit, guided practice, complete starter answers, and license. Original excerpt page numbers are retained.
