Block tower graphing

This morning Uheina and George were building a tower, it got so tall that it couldn't support itself. 

The tower caught Avens attention and she decided to try and build a tower as well using the building blocks.

Then came the comparisons and estimations "My tower is taller than your one" "there are not enough blocks to make it that tall" "What if we use the yellow ones?" "I think green will be the tallest because there are lots of green blocks" 

Soon we had 4 different towers being built. At the beginning Aven's towers kept falling over once they got to a certain height. George saw that Aven was struggling so he showed Aven how to make the strongest and tallest tower.

 I asked the children how we could compare them once all the towers were built. Uheina thought if we use string we could measure them. 

Then after seeing Uheina lay her tower down, George thought we could lay them all down beside each other. So Miss Stella went and got a large white roll of paper. First Miss Stella said that the big purple tower would fit on the paper but George told me to put it long ways rather than across the paper. 

Then came the other towers. George was really good at teaching us that all the towers needed to start at the same point to make sure it is a fair comparison. 

Aven laid down the red tower on top of the blue. This triggered a discussion around how a comparison works and that we want to be able to see how tall each colour separately. Aven then moved the red tower next to the blue one.

The children then decided as a group that is was not fair that the tall purple tower was apart of our pictograph because it was using different blocks. They said that it won but had to come off.

Here is a proud graphing team!!!

This is the children's analysis of their information gathered.
