Building the 5-Region Comparative Chronology Strip - 600 to 1500 CE

Objectives
  • Students engage with the lesson 2 content described in title and narrative.
  • Students apply unit-wide routines (Cultural Care Promise, present-tense protocol, OWN-VOICE CHECK) to the lesson 2 content.

Lesson plan

Warm-up

5 min

Calendar Circle + recite Cultural Care Promise + introduce Comparative Chronology Strip (MG-2)

Teacher moves
  • Lead routine standing
  • Affirm continuity with prior lessons

Direct instruction

15 min

Show the 5 bands of MG-2 vertically aligned. Read aloud one event from each band at the same century (e.g., 'In the 1300s, in the Andes, the Inca state was growing; in West Africa, Mansa Musa ruled the Mali Empire; in East Asia, the Song dynasty continued; in Polynesia, Aotearoa was being settled; in our local place, ___' [teacher-localized]). Pause and let children notice all of these happened at the SAME TIME.

Key examples
  • Notice how two very different cultures were both producing significant events at the same time. History is not one timeline - it is many timelines running together.
    model The 1200s. In West Africa, the Mali Empire was being founded by Sundiata Keita. In Polynesia, the Maori were settling Aotearoa.
    prompt What was happening in West Africa in the same century when Hokule'a's ancestors voyaged to Aotearoa?
Checks for understanding
  • Show me the 1300s on the strip. Name one event from each of the five bands.
Sourcework

Children examine the Comparative Chronology Strip (MG-2) as a chart-as-source. They identify the year markers (4-digit place-value cross-link to Math G3 Fall) and the same-century event pairings. The strip itself is a secondary-source synthesis of underlying primary-source archaeological and historical scholarship.

MG-2 96x24-inch laminated chart mounted along one full wall. Children physically place same-century event cards across the five bands. The intentional 5-band parallel structure is the unit's most distinctive chronological move - it shows the 600-1500 CE timeline synchronously across local place + Andes + West Africa + East Asia + Polynesia.

Mounted along one full classroom wall at child-eye-height. The INTENTIONAL 5-band parallel structure is the unit's most distinctive chronological move - it corrects the common 'rest of the world stopped while Europe did things' framing by showing 600-1500 CE synchronously across five regions. Children add localized events to the timeline lesson-by-lesson. Teacher Localization Note: Band 1 (local place) must be replaced with locality-specific events; the four other bands are universal. Date ranges are presented with circa-precision honoring the actual state of the scholarship.

Guided practice

15 min
Tasks
  • In pairs, pick TWO bands. Find one event from each band that happened in the same century. Write the synchronous pair on a card.
    scaffold Sentence frame: 'In the ___ century, in [band 1] ___, and at the same time in [band 2] ___'
  • Post your synchronous pair under the correct century marker on MG-2
    scaffold Teacher checks each pair before posting

40 standardized 3x5-inch laminated event cards with year, region, one-line event description, and a source citation badge. Band 1 (local place) cards are teacher-localized via consultation with the local tribal education office. Each card has a colored border matching its band on MG-2. Children handle and place these physically on the wall strip.

Teacher notes

Lesson 2 is the unit's structural anchor. The teacher must localize Band 1 (local place) BEFORE lesson 2 - consult local tribal education office for Indigenous-nation pre-1500 history. Cross-link to Math G3 Spring fractions-on-a-number-line via 'halfway between 600 and 1500 CE' work.
