Explain and Compare Linear Relationships

Library package prepared 2 November 2026. Revised guides are marked with that date; unchanged teacher and student/core editions retain their file labels. Use the matching current guide supplied beside each task.

Keep this package with the teacher. Choose one stage at a time. Distribute only its student files and required sources. Teacher keys and reserved independent/follow-up/later tasks have separate folders. A teaching model may intentionally contain an answer; keep checks for later use aside during teaching.

PDF and available native editable files are included. Open the linked preparation page for accessible browser versions, current printing directions and any additional equipment. Online links need an internet connection. Timings are planning estimates; these materials do not establish classroom effectiveness or test equivalence.

Explain and Compare Linear Relationships

Find change per input unit from unequal intervals, recover an initial value from nonzero observations, and compare linear models. Supplied teaching, targeted responses, different later checks and transfer include complete keys.

Prerequisites: Students can interpret paired quantities and per-one meaning, coordinates and nonzero starting amounts. Use the linked Grade 6 ratio/per-one and selected Grade 7 lessons when these need teaching.

Prepare: Read the Start Here selections; preparation time depends on the selected route. Timing: Use the teacher guide to plan the selected route
