Reflection: Checks for Understanding The Power of Triangles - Section 4: Wrap-Up


For a quick check of their understanding, I had the children draw a diagram and then write their observations.  I was looking for the children to write that adding the longer piece made the shape more stable.  It was interesting to see how different children worded the answer in different ways.  I was pleased that every child was able to write an idea that showed that they understood the concept.  I also expected them to draw and label a simple diagram.
