Last year, I used this as one of the "first week back" activities. It is a useful thing to do on the first or second day back at school. It's very easy to prepare and it's a nice paired activity to allow the children to work with another child and to get to know the classroom at the same time.
You simply take photos of different things in the classroom like glue sticks, tissues, paint brushes, exercise books, a calendar, scissors, etc. Put these pictures on a sheet with a box underneath for ticking! Add a space for the name and date et voilá!
The children then walk around the room in their pairs looking for the items and ticking what they have found.
Here's a terrible quality picture of mine from last year! I don't have a copy of the original file unfortunately!
