Sort items into then, now, or both across categories such as school, toys, transportation, and communication, explaining the reasoning for at least one.
This week you pull together everything you have learned about "long ago" versus "now." Things change over time in categories like school, toys, transportation, clothing, and how people talk to each other far away.
Some things belong ONLY in the past, some belong ONLY to today, and some things belong to BOTH -- they have not changed at all.
Mastery looks like: They can sort multiple items correctly into then, now, or both, and explain their reasoning for at least one.
Common stumbles: Sorting by a quick guess rather than real reasoning, or forgetting that some things belong in the "both" category.
