Students analyze real data on education access and quality to understand how shortages in teachers, doctors, and nurses affect societies.
Using ratios and proportions, they explore why education quality is essential for skilled professions and sustainable development.

Students analyze real data on cocoa production and yields to calculate land use over time. Using ratios and percentages, they estimate export levels, explore how chocolate demand impacts forests and farmers, and propose sustainable solutions and responsible consumer choices.

Students explore how exponential and linear models can describe population and food production trends using FAO–World Bank data. They compare growth rates and discuss whether global food supply can sustainably meet population needs.

Learners compute and compare water footprints per serving using real data.
They rank food options under a daily water-use constraint and justify trade-offs between nutrition, sustainability, environmental impact, and long-term resource management.

Students explore how phone notifications impact attention and sleep. 

Using real data, they build a linear model to estimate time lost during study, compare habits across students, and discuss how healthy digital choices support learning and well-being.

Students use real fishery data to estimate parameters for a logistic model, identify equilibrium and collapse thresholds, and explore how mathematics can support sustainable fishing policies.
