About This Activity

Leo brushed dirt off a golden artifact buried deep underground.

Teacher Tip

After the matching activity, have students pretend each vocabulary word is an artifact in a dig box — ask them to arrange TOPIC and DETAIL side by side to show how a main idea is always supported by smaller facts, just like a dig site is understood through individual artifacts.

EVIDENCEOld bones or tools that prove something really happened.

SUMMARYA short retelling of what the whole excavation report said.

DETAILOne small fact that supports the bigger discovery.
