Show MG-9 Trade Networks Anchor with Trans-Saharan caravan routes highlighted. Walk through salt-and-gold trade: SALT mined in the central Sahara (Taghaza) and traded south; GOLD mined in West African fields (Bambuk, Bure) and traded north. Camel caravans crossed the Sahara. Timbuktu sat at the meeting point. Show Mansa Musa's reign c. 1312-1337 and tell the story of his hajj c. 1324. Read aloud Rumford's Traveling Man. Show contemporary Timbuktu manuscript conservator photograph.

Key examples
  • Notice: economic incentive (D2.Eco.2) is the historian's tool for understanding why people make long journeys.
    model Because salt and gold were valuable enough to make the journey worth the risk. Salt was needed for preserving food. Gold was needed for currency, ornament, and tribute. Both were scarce in different places - which made the trade profitable.
    prompt Why did caravans cross the Sahara even though it was dangerous?
Checks for understanding
  • Who was Mansa Musa? Why is Timbuktu famous?
Sourcework

Children examine MG-11 photo 6 (Timbuktu manuscript conservator) as a primary source representing living scholarly tradition. Apply LIVING-CULTURE-PHOTO routine. They examine Rumford's picture book (built from Ibn Battuta's 14th-century Rihla travel account) as a secondary-source bridge to own-voice primary sources.

Mounted on classroom wall at child-eye-height. The intentional FOUR-NETWORK framing teaches that trade networks operate at many scales (continental, intercontinental, oceanic) and on many cultural logics (state-built for Inca; merchant-caravan for Trans-Saharan; merchant-caravan + maritime for Silk Roads; wayfinder-voyaging for Polynesian). Children reference this anchor in lesson 15 and trace ONE innovation along ONE network as their cultural-diffusion exercise.

MG-11 photo 6 - high-resolution contemporary photograph of a Mande scholar at the Mamma Haidara Library or Ahmed Baba Institute in Timbuktu working with one of the thousands of preserved medieval manuscripts. 4-line caption: 'Mamma Haidara Library conservator, Timbuktu, Mali, 2017 (photo credit).' CRITICAL: the photo shows a SCHOLAR at work, not a tourist - centering own-voice.

Mounted on classroom wall as a grouped 4x4 grid. Used in lessons 7-14 as the LIVING-CULTURE PHOTO routine source set. The 4-per-culture standard is INTENTIONAL - equal weighting. Critical teacher protocol: source these photos with permission from the cultural organizations represented (CTTC for Andean; Polynesian Voyaging Society for Polynesian; Mande cultural organizations; Chinese cultural organizations). The 'photographer credit' and 'year' lines enforce that these are real contemporary images by named photographers in named years - not generic stock photography.

Teacher notes

Lesson 10 closes the Mande/Mali two-lesson arc. The 'Mansa Musa is the richest person in history' framing is reductive - reframe: Mansa Musa was ONE Mali leader; the Mali Empire had complex governance, scholarship, and material culture. The Timbuktu manuscript photograph refutes the colonial-era claim that 'West Africa had no written tradition.'
