This was the children's first experience with the tally graph. We had graphed several times before doing a picture graph and a bar graph. But this was the first time they'd used tally graphs. The children spent at least 10 or 15 minutes graphing the parts of the fire truck that they had asked about on their web. I made a graph for them with a picture of a tire and a column for them to make their tally marks, and a picture of the windows, etc. They took the clipboards and just walked around the fire truck, placed a mark for each object they saw, then counted their marks. They, for the most part, were very successful. They really enjoyed the counting as the numbers got higher and higher. "There are eight windows on this fire truck!" They were amazed! They started to count the hoses. The firefighter said, "Oh, I'm going to have to bring them down. There are a lot of hoses on this fire truck!" As their counting grew, they just got more and more excited about putting those tally marks on the paper the right way.
