Design a lesson that still works with little or no data

WHAT YOU ARE MAKING A low-data or offline version of one real lesson for secondary-school learners. It may use SMS, WhatsApp, downloadable audio, a lightweight web page, print or a combination. START HERE Choose one lesson and one learner group. Ask a teacher and at least three learners what devices, data and electricity they can reliably use. Design for the weakest realistic connection, not the best one. YOUR SUBMISSION Share the lesson prototype, a data-size estimate, instructions for the teacher and learner, an offline fallback and notes from testing it on a low-end phone or constrained connection. KEEP IT SAFE AND HONEST Do not collect children's contact details for testing. Use material you created or have permission to adapt. Do not require a new paid device or subscription. GOOD WORK LOOKS LIKE The lesson loads or can be received under the stated conditions, the learner can complete a meaningful activity, and the teacher can see or discuss the result.
