These are 17 flashcard printables of natural materials and their sources- for example: we get dairy from cow and honey from a bee. I use them for the science unit on natural and man made resources. They're up on the word wall for an entire unit.
There are times when children don't know that we get milk from a cow and not from a shop. This is especially true in an urban scenario. These cards are my savior to teach vocabulary words and spellings.
Download them, print them and put it up in your classrooms. Let me know how your children react to these!
