Grade 7 math · 40 minutesWhich ticket table is proportional?
Content: Table A shows 2, 4, 6 tickets costing $6, $12, $18. Table B shows 2, 4, 6 tickets costing $8, $14, $20. Students decide which table is proportional and justify with unit rates. (A is $3 per ticket throughout; B is $4, $3.50, then about $3.33.)
Language: Compare rates and justify with two values.
- Launch 5: Display both tables; notice and mark numbers.
- Model 7: Find the cost per ticket in A; teach per, constant, proportional in context.
- Partner 10: Each student explains one table, partner asks for evidence.
- Apply 13: Decide independently and write a two-sentence proof.
- Close 5: Revise one explanation using a second row.
“In table ___, ___ tickets cost ___. The unit rate is ___. It is/is not proportional because ___.”
Science · 40 minutesWhat does the investigation show?
Content: Students compare two plants grown with different light directions. Use actual class photos or a reliable set of observations; distinguish what is visible from a possible explanation.
Language: Describe an observation, then explain a claim using evidence.
- Launch 5: Show both images with the question visible.
- Model 7: Label one observation; teach observe, evidence, direction.
- Partner 10: Partners sort observations from explanations and defend a choice.
- Apply 13: Draw, label, and write a claim with two observations.
- Close 5: Revise an unsupported claim to cite visible evidence.
“I observed ___ in plant ___. This supports ___ because ___.”
