Cross-Reference Matrix
Where the four subjects meet
Every week of Grade 6 has at least one explicit cross-curricular connection — a single lesson that lives in two subjects at once. Use this as your planning matrix, not as extra work to add on.

Eratosthenes measures the Earth
Re-create the shadow experiment that gave us a value for Earth's circumference — using sun-angle data the Greeks could measure.
Do this: Cross-discipline lab: students use two sticks, sun-angle data, and proportional reasoning to calculate Earth's circumference (also a 6.RP.A.3 connection).
MS-ESS1-16.RP.A.3D2.Geo.1.6-8 - MathScienceWk 15, 16

Empires & Encounter Across Continents
Big question: What holds an empire together — and what makes it fall apart?
- MathWk 19, 20
Solving for unknown legion strength
Roman army problems become one-variable equation practice.

Surface area & volume of a Roman aqueduct
Measure flow rate using cross-sectional area and slope.
Do this: Build a paper-and-foil aqueduct, calculate cross-sectional area (6.G.A.1) and volume per minute; relate to MS-ESS2 water cycle.
6.G.A.16.G.A.2MS-ESS2-4 - ELAWk 23, 24
Silk Road trade-route research project
Each student takes one stop on the Silk Road and writes an informative report grounded in 2+ primary sources.
Do this: Research process (W.6.7) + informative writing (W.6.2) with a one-page route map deliverable.
W.6.2W.6.7D2.Eco.6.6-8 - ScienceWk 25
Geoscience of the Silk Road
Why does the route bend where it bends? Mountains, deserts, and rivers explain it.
Do this: Overlay a physical-features map on a Silk Road map; annotate geo-causes for each route segment.
MS-ESS2-2D2.Geo.4.6-8 - ELAWk 26, 27
Comparative-religions information essay
Compare the spread of Buddhism and early Christianity along trade routes.
Do this: 5-paragraph compare/contrast essay (W.6.2) with one primary source from each tradition.
W.6.2RI.6.2D2.His.14.6-8

Medieval Worlds & Cultural Synthesis
Big question: How did the medieval world build the science, math, and institutions we use today?
- MathWk 28, 29
Mansa Musa's hajj as a statistics problem
Use historic gold-flow data to study mean, median, range, and shape.
