Trade with a villager in Minecraft

What can we use if emeralds, villagers, or a paper notebook are hard to find for this activity?

If you don't have emeralds, use the /give command to add emeralds to your inventory before Step 6, if there are no villagers create job-site blocks to attract them, and use an in-game book or a phone Notes app instead of a paper notebook to record trades.

What should we do if a villager won't trade or shows no profession when we try to open their trade screen?

If a villager has no profession in Step 3, place the correct workstation (for example a Lectern for a Librarian) next to them so they claim it, and if trades are grayed out wait for the trade cooldown to expire before trying to put emeralds into the trade slot in Step 11.

How can I adapt the steps for younger or older children?

For ages 5–7 simplify Steps 6–9 by helping them count emeralds and pick one best item while writing a single line in the notebook, and for ages 10+ have them compare multiple villagers' emerald costs, log results over several trades, and build a short trading plan to post on DIY.org.

How can we extend or personalize the trading activity after completing the basic steps?

Extend the activity by building a labeled trading hall near the village, assigning villagers to specific workstations, recording emerald cost changes over repeated trades in your notebook or a spreadsheet, and then sharing that trading plan and findings on DIY.org.
