After reading lots of informational books about fish and doing a guided drawing lesson, the children each made 3 fish. They could be any size and color.
Once they were done, they had to place them on a large and very long piece of black paper that took up most of our room. We laid them out according to size, smallest to largest. They had to first estimate where they thought it should go. Then, when some got too close to tell, they measured with cubes.
We realized that some appeared longer because they were wider but they ended up being shorter after we measured them. The children had to make adjustments and then we all glued them down in order. The end result is awesome! It's in our hallway and the kids were so excited!
