My Grade 4s did a little research on the Canadian Shield region of Alberta. After, they were asked to make a list of 15 items that represented things in this region. For example, a plastic Lego tree represents the forests in the region.
I asked the students to bring items from home or to make them in class. The items were placed in a baggie and filled with rice or noodles. I borrowed the rice from the sensory tables in the Kindergarten and Grade 1 rooms.
Students typed their list of items and attached it to the bag. Then students switched bags and searched for the items on the list.
