This product contains both a whole class and small group version of the same I have/Who activity. As I teach 6th grade, I have found that having the kids work in small groups to create a chain with the cards is much more interactive and engaging. The chain for the small groups has a few less cards to make it a bit more managable--it is in blue and contains a start and finished card.
The whole class set contains 24 cards and is in red.
It is set up for landscape mode, so you will need to select that when printing. I prefer the cards to be a bit smaller for the chains, so I print it in portrait mode with 2 pages per page (multiple pages option.)
